JET Select Component

Description: JET Select enhances a html select and option elements into a Select that supports single-select, multi-select and search filtering. User can filter down the results by typing a search term into the select box or the search box. This search box is displayed in the dropdown container only when the results size is greater than the value specified in the minimumResultsForSearch option or the user starts typing while the select box has the focus.

A JET Select can be created with the following markup. By default, it creates a single-select Select.


<select data-bind="ojComponent: {component: 'ojSelect'}">
    <option value="option 1">option 1</option>
    <option value="option 2">option 2</option>
    <option value="option 3">option 3</option>
    <option value="option 4">option 4</option>
</select>

Select Tab In Set focus to the select. If hints, title or messages exist in a notewindow, pop up the notewindow.
Label's help icon Enter Go the Help Source URL.
Tab In Show help definition text.

Disabled option items receive no highlight and are not selectable.

Reading direction

As with any JET component, in the unusual case that the directionality (LTR or RTL) changes post-init, the Select must be refresh()ed.

Pseudo-selectors

The :oj-select pseudo-selector can be used in jQuery expressions to select JET Select. For example:

$( ":oj-select" ) // selects all JET Select on the page
$myEventTarget.closest( ":oj-select" ) // selects the closest ancestor that is a JET Select

Accessibility

It is up to the application developer to associate the label to the select component. For select, you should put an id on the select, and then set the for attribute on the label to be the select's id.

Label and Select

For accessibility, you should associate a label element with the select by putting an id on the select, and then setting the for attribute on the label to be the select's id.

The component will decorate its associated label with required and help information, if the required and help options are set.

JET for jQuery UI developers

Event names for all JET components are prefixed with "oj", instead of component-specific prefixes like "Select".

Initializer

.ojSelect()

Creates a JET Select.
Source:
Examples

Initialize the Select with no options specified:

$( ".selector" ).ojSelect();

Initialize the Select with some options:

$( ".selector" ).ojSelect( { "placeholder": "Select a value." } );

Initialize the Select via the JET ojComponent binding:

<div id="select" data-bind="ojComponent: { component: 'ojSelect' }">

Options

contextMenu :Element|Array.<Element>|string|jQuery|NodeList

Identifies the JET Menu that the component should launch as a context menu on right-click, Shift-F10, Press & Hold, or component-specific gesture. If specified, the browser's native context menu will be replaced by the specified JET Menu.

The value can be an HTML element, JQ selector, JQ object, NodeList, or array of elements. In all cases, the first indicated element is used.

To specify a JET context menu on a DOM element that is not a JET component, see the ojContextMenu binding.

To make the page semantically accurate from the outset, applications are encouraged to specify the context menu via the standard HTML5 syntax shown in the below example. When the component is initialized, the context menu thus specified will be set on the component.

There is no restriction on the order in which the JET Menu and the referencing component are initialized. However, when specifying the Menu via the HTML attribute, the referenced DOM element must be in the document at the time that the referencing component is initialized.

After create time, the contextMenu option should be set via this API, not by setting the DOM attribute.

The application can register a listener for the Menu's beforeOpen event. The listener can cancel the launch via event.preventDefault(), or it can customize the menu contents by editing the menu DOM directly, and then calling refresh() on the Menu.

To help determine whether it's appropriate to cancel the launch or customize the menu, the beforeOpen listener can use component API's to determine which table cell, chart item, etc., is the target of the context menu. See the JSDoc and demos of the individual components for details. Keep in mind that any such logic must work whether the context menu was launched via right-click, Shift-F10, Press & Hold, or component-specific touch gesture.

Default Value:
  • null
Inherited From:
Source:
Examples

Initialize a JET component with a context menu:

// via recommended HTML5 syntax:
<div id="myComponent" contextmenu="myMenu" data-bind="ojComponent: { ... }>

// via JET initializer (less preferred) :
// Foo is the component, e.g., InputText, InputNumber, Select, etc.
$( ".selector" ).ojFoo({ "contextMenu": "#myMenu" });

Get or set the contextMenu option, after initialization:

// getter
// Foo is the component, e.g., InputText, InputNumber, Select, etc.
var menu = $( ".selector" ).ojFoo( "option", "contextMenu" );

// setter
// Foo is the component, e.g., InputText, InputNumber, Select, etc.
$( ".selector" ).ojFoo( "option", "contextMenu", ".my-marker-class" );

Set a JET context menu on an ordinary HTML element:

<a href="#" id="myAnchor" contextmenu="myMenu" data-bind="ojContextMenu: {}">Some text

disabled :boolean

Whether the component is disabled. The element's disabled property is used as its initial value if it exists, when the option is not explicitly set. When neither is set, disabled defaults to false.

The 2-way disabled binding offered by the ojComponent binding should be used instead of Knockout's built-in disable and enable bindings, as the former sets the API, while the latter sets the underlying DOM attribute.

When the disabled option changes due to programmatic intervention, the component may clear messages and run validation in some cases.

  • when a required component is initialized as disabled {value: null, required:true, disabled: true}, deferred validation is skipped.
  • when a disabled component is enabled,
    • if component is invalid and showing messages then all component messages are cleared, and full validation run using the display value.
      • if there are validation errors, they are pushed to messagesShown option.
      • if no errors result from the validation, the value option is updated. Page authors can listen to the optionChange event on the value option to clear custom errors.
    • if component is valid and has no errors then deferred validation is run.
      • if there is a deferred validation error, then messagesHidden option is updated.
    • if component is invalid and deferred errors then component messages are cleared and deferred validation re-run.
      • if there is a deferred validation error, then messagesHidden option is updated.
  • when enabled component is disabled then no validation is run and the component appears disabled.

Default Value:
  • false
Inherited From:
Source:
Example

Initialize component with disabled option:

$(".selector").ojFoo({"disabled": true}); // Foo is InputText, InputNumber, Select, etc.

displayOptions :Object|undefined

Display options for auxilliary content that determines where it should be displayed in relation to the component.

The types of messaging content for which display options can be configured include messages, converterHint, validatorHint and title.
The display options for each type is specified either as an array of strings or a string. When an array is specified the first display option takes precedence over the second and so on.

JET editable components set defaults that apply to the entire app/page. It is possible to override the defaults on a per instance basis as explained in the examples below or change defaults for the entire application using oj.Components#setDefaultOptions method. It is much easier to change the defaults using setDefaultOptions once rather than putting the displayOptions option on every component instance.

When displayOptions changes due to programmatic intervention, the component updates its display to reflect the updated choices. For example, if 'title' property goes from 'notewindow' to 'none' then it no longer shows in the notewindow.

A side note: title and message detail text can include formatted HTML text, whereas hints and message summary text cannot. If you use formatted text, it should be accessible and make sense to the user if formatting wasn't there. To format the title, you could do this:

<html>Enter <b>at least</b> 6 characters</html>

Properties:
Name Type Argument Description
converterHint Array | string <optional>
supported values are 'placeholder', 'notewindow', 'none'. The default value is ['placeholder', 'notewindow']. When there is already a placeholder set on the component, the converter hint falls back to display type of 'notewindow'. To change the default value you can do this -
E.g. {'displayOptions: {'converterHint': ['none']}}
validatorHint Array | string <optional>
supported values are 'notewindow', 'none'. To change the default value you can do this -
{'displayOptions: {'validatorHint': ['none']}}
messages Array | string <optional>
supported values are 'notewindow', 'inline', 'none'. The default is 'inline'. To change the default value you can do this -
E.g. {'displayOptions: {'messages': 'none'}}
title Array | string <optional>
supported values are 'notewindow', 'none'. To change the default value you can do this -
E.g. {'displayOptions: {'title': 'none'}}
Default Value:
  • {
      'messages': ['inline'],
      'converterHint': ['placeholder', 'notewindow'],
      'validatorHint': ['notewindow'],
      'title': ['notewindow']
    }
Since:
  • 0.7
Inherited From:
Source:
Examples

Override default values for displayOptions for messages for the entire application:

// messages will be shown in the notewindow for the application.
oj.Components.setDefaultOptions({
   'editableValue':
   {
     'displayOptions': 
     {
       'messages': ['notewindow']
     }
   }
});

Override default values for displayOptions for one component instance:

// In this example, the instance of ojFoo changes its displayOptions from the defaults.
// The 'converterHint' is none, the 'validatorHint' is none and the 'title' is none,
// so only the 'messages' will display in its default state.
// For most apps, you will want to change the displayOptions app-wide
// for all EditableValue components, so you should use the
// oj.Components#setDefaultOptions function instead (see previous example).
//
// Foo is InputText, InputNumber, Select, etc.
$(".selector").ojFoo("option", "displayOptions", {
  'converterHint': 'none',
  'validatorHint': 'none',
  'title' : 'none'
});

help :Object.<string, string>

Help information that goes on the label. When help is set on the input component, then help information is added to the input's label.

The properties supported on the help option are:

Properties:
Name Type Argument Description
definition string <optional>
this is the help definition text. It is what shows up when the user hovers over the help icon, or tabs into the help icon, or press and holds the help icon on a mobile device. No formatted text is available for the help definition attribute. The default value is null.
source string <optional>
this is the help source url. If present, the help icon's anchor's target is this source. For security reasons we only support urls with protocol http: or https:. If the url doesn't comply we ignore it and throw an error. The default value is null. Pass in an encoded URL since we do not encode the URL.
Default Value:
  • {help : {definition :null, source: null}}
Inherited From:
Source:
Examples

Initialize the input with the help definition and external url information:

// Foo is InputText, InputNumber, Select, etc.
$( ".selector" ).ojFoo({ "help": {"definition":"some help definition, "source":"some external url" } });

Set the help option, after initialization:

// setter
// Foo is InputText, InputNumber, Select, etc.
$( ".selector" ).ojFoo( "option", "help", {"definition":"fill out the name", "source":"http:\\www.oracle.com" } );

help.definition :string

list :string|null|undefined

The id of the html list for the select.
Source:
Examples

Initialize the select with the list option specified:

$( ".selector" ).ojSelect( { "list": "list" } );

The list points to a html ul element. The value for the list item should be specified with oj-data-value field. By default, we use the first text node for search filtering. An optional oj-data-label field can be added to the list item, in which case it will take precedence over the text node.

<ul id="list">
<li oj-data-value="li1">Item 1</li>
<li oj-data-value="li2">Item 2</li>
</ul>

messagesCustom :Array|undefined

List of messages an app would add to the component when it has business/custom validation errors that it wants the component to show. When this option is set the messagesShown option is also updated and the message shows to the user right away. To clear the custom message, set code class="prettyprint">messagesCustom back to an empty array.
Each message in the array is either an instance of oj.Message or an object that duck types it. See oj.Message for details.

An optionChange event is triggered every time this option value changes.

Default Value:
  • empty array when no option is set.
Since:
  • 0.7
Inherited From:
Source:
See:
Examples

Get the current list of app messages using messagesCustom option:

// Foo is InputText, InputNumber, Select, etc.
var customMsgs = $(".selector").ojFoo("option", "messagesCustom"); 

Clear all app messages set on the component:

// Foo is InputText, InputNumber, Select, etc.
$(".selector").ojFoo("option", "messagesCustom", []); 

Set app messages using the messagesCustom option:

var msgs = [];
msgs.push({'summary': 'Error Summary', 'detail': 'Error Detail'}); 
// Foo is InputText, InputNumber, Select, etc.
$(".selector").ojFoo("option", "messagesCustom", msgs);

<readonly> messagesHidden :Array|undefined

List of messages currently hidden on component, these are added by component when it runs deferred validation. Each message in the array is either an instance of oj.Message or an object that duck types it. See oj.Message for details.

This is a read-only option so page authors cannot set or change it directly.

An optionChange event is triggered every time this option value changes.

These messages are not shown to the end-user by default, but page author can show hidden messages using the showMessages method.

Default Value:
  • empty array when no option is set.

<readonly> messagesShown :Array|undefined

List of messages currently shown on component, these include messages generated both by the component and ones provided by app using messagesCustom. Each message in the array is either an instance of oj.Message or an object that duck types it. See oj.Message for details.

This is a read-only option so page authors cannot set or change it directly.

An optionChange event is triggered every time its value changes.

Messages retrieved using the messagesShown option are by default shown in the notewindow, but this can be controlled using the 'messages' property of the displayOptions option.

minimumResultsForSearch :number

The threshold for showing the search box in the dropdown when it's expanded. The search box is always displayed when the results size is greater than the threshold, otherwise the search box is initially turned off. However, the search box is displayed as soon as the user starts typing.
Default Value:
  • 15

multiple :boolean

If multi-select is enabled for the select.
Default Value:
  • false
Source:
Example

Initialize the Select with the multiple option specified:

$( ".selector" ).ojSelect( { "multiple": true } );

options :Array

The option items for the Select. Instead of providing a list of option items, they can be specified as an array of objects containing value and label. The value is used as the value of the option item and label as the label.
Source:
Examples

Initialize the Select with the options option specified:

$( ".selector" ).ojSelect( { "options": [{value: 'option1', label: 'option1'}, {value: 'option2', label: 'option2'}, {value: 'option3', label: 'option3'},] } );

Initialize the Select with group data:

$( ".selector" ).ojSelect( { "options": [{label : 'group1', children: [{value: 'option1', label: 'option1'}, {value: 'option2', label: 'option2'}]}, {label: 'group2', children: [{value: 'option3', label: 'option3'}]} ] } );

optionsKeys :Object

Specify the key names to use in the options array.
Source:
Examples

Initialize the Select with optionsKeys specified. This allows the key names to be redefined in the options array.

$( ".selector" ).ojSelect( { "optionsKeys": {value : "state_abbr", label : "state_name"} } );

Redefine keys for data with subgroups.

$( ".selector" ).ojSelect( { "optionsKeys": {label : "regions", children : "states", childKeys : {value : "state_abbr", label : "state_name"}} } );

pickerAttributes :Object

Attributes specified here will be set on the picker DOM element when it's launched.

The supported attributes are class and style, which are appended to the picker's class and style, if any. Note: 1) pickerAttributes is not applied in the native renderMode. 2) setting this option after component creation has no effect.

Default Value:
  • null
Source:
Examples

Initialize the select specifying a set of attributes to be set on the picker DOM element:

$( ".selector" ).ojSelect({ "pickerAttributes": {
  "style": "color:blue;",
  "class": "my-class"
}});

Get the pickerAttributes option, after initialization:

// getter
var select = $( ".selector" ).ojSelect( "option", "pickerAttributes" );

placeholder :string|null|undefined

The placeholder text to set on the element.

If the placeholder option is specified to a string, ojselect will adds a placeholder item at the beginning of the dropdown list with

  • displayValue: placeholder text
  • value: an empty string
The placeholder item in the dropdown is selectable. However, it's not a valid choice, i.e. validation will fail if the select component is a required field.

The placeholder item doesn't participate in the filtering, so it will not appear in the result list with a filter specified.

Placeholder text can be an empty string, please see the select placeholder cookbook demo.

Default Value:
  • undefined
Source:
Example

Initialize the select with the placeholder option specified:

$( ".selector" ).ojSelect( { "placeholder": "Please select ..." } );

renderMode :string

The renderMode option allows applications to specify whether to render ojSelect in JET or as a HTML Select tag. Valid Values: jet, native
  • jet - Applications get full JET functionality.
  • native - Applications get the HTML Select tag functionality and additional JET features below:
    • validation
    • placeholder
    • options (ko.observableArray)
    • list
    • optionKeys
    With native renderMode, the functionality that is sacrificed compared to jet rendermode is:
    • no search box (no filtering)
    • for multiple select, only number of selected items is displayed in the selectbox, not the selected values
    • beforeExpand event isn't fired when the popup picker opens.
    • only one level nesting optgroups in the popup picker due to the HTML optgroup limitation
    • no image support in the option list
    • All Sub-IDs are not available in the native renderMode.
    • pickerAttributes is not applied in the native renderMode.
Default Value:
  • value depends on the theme. In alta-android, alta-ios and alta-windows themes, the default is "native" and it's "jet" for all other themes.
Source:
Example

Get or set the renderMode option for an ojSelect after initialization:

// getter
var renderMode = $( ".selector" ).ojSelect( "option", "renderMode" );

// setter
$( ".selector" ).ojSelect( "option", "renderMode", "native" );

required :boolean

Whether the component is required or optional. When required is set to true, an implicit required validator is created using the validator factory - oj.Validation.validatorFactory(oj.ValidatorFactory.VALIDATOR_TYPE_REQUIRED).createValidator(). Translations specified using the translations.required option and the label associated with the component, are passed through to the options parameter of the createValidator method.

When required option changes due to programmatic intervention, the component may clear messages and run validation, based on the current state it's in.

Running Validation

  • if component is valid when required is set to true, then it runs deferred validation on the option value. This is to ensure errors are not flagged unnecessarily.
    • if there is a deferred validation error, then messagesHidden option is updated.
  • if component is invalid and has deferred messages when required is set to false, then component messages are cleared but no deferred validation is run.
  • if component is invalid and currently showing invalid messages when required is set, then component messages are cleared and normal validation is run using the current display value.
    • if there are validation errors, then value option is not updated and the error pushed to messagesShown option.
    • if no errors result from the validation, the value option is updated; page author can listen to the optionChange event on the value option to clear custom errors.

Clearing Messages

  • Only messages created by the component are cleared. These include ones in messagesHidden and messagesShown options.
  • messagesCustom option is not cleared.

Supported Values:
Name Type Description
false boolean implies a value is not required to be provided by the user. This is the default.
true boolean implies a value is required to be provided by user and the input's label will render a required icon. Additionally a required validator - oj.RequiredValidator - is implicitly used if no explicit required validator is set. An explicit required validator can be set by page authors using the validators option.
Default Value:
  • false
Since:
  • 0.7
Source:
See:
Examples

Initialize the component with the required option:

$(".selector").ojSelect({required: true}); 

Initialize required option from html attribute 'required':

<select required/>
// retreiving the required option returns true $(".selector").ojSelect("option", "required");

Customize messages and hints used by implicit required validator when required option is set:

<select type="text" value="foobar" required data-bind="ojComponent: {
  component: 'ojSelect', 
  value:  'Chrome', 
  required: true,
  translations: {'required': {
                hint: 'custom: you must enter something',
                messageSummary: 'custom: \'{label}\' is Required', 
                messageDetail: 'custom: please enter a valid value for \'{label}\''}}}"/>

rootAttributes :Object

Attributes specified here will be set on the component's root DOM element at creation time. This is particularly useful for components like Dialog that wrap themselves in a new root element at creation time.

The supported attributes are id, which overwrites any existing value, and class and style, which are appended to the current class and style, if any.

Setting this option after component creation has no effect. At that time, the root element already exists, and can be accessed directly via the widget method, per the second example below.

Default Value:
  • null
Inherited From:
Source:
Examples

Initialize a JET component, specifying a set of attributes to be set on the component's root DOM element:

// Foo is the component, e.g., Menu, Button, InputText, InputNumber, Select, etc.
$( ".selector" ).ojFoo({ "rootAttributes": {
  "id": "myId",
  "style": "max-width:100%; color:blue;",
  "class": "my-class"
}});

After initialization, rootAttributes should not be used. It is not needed at that time, as attributes of the root DOM element can simply be set directly, using widget:

// Foo is the component, e.g., Menu, Button, InputText, InputNumber, Select, etc.
$( ".selector" ).ojFoo( "widget" ).css( "height", "100px" );
$( ".selector" ).ojFoo( "widget" ).addClass( "my-class" );

title :string|undefined

Represents advisory information for the component, such as would be appropriate for a tooltip.

When a title is present it is by default displayed in the notewindow, or as determined by the 'title' property set on the displayOptions option. When the title option changes the component refreshes to display the new title.

JET takes the title attribute off the input and creates a notewindow with the title text. The HTML title attribute only shows up on mouse blur, not on keyboard and not in a mobile device. So title would only be for text that is not important enough to show all users, or for text that you show the users in another way as well, like in the label. Also you cannot theme the native browser's title window like you can the JET notewindow, so low vision users may have a hard time seeing it. For these reasons, the JET EditableValue components do not use the HTML's title attribute.

To include formatted text in the title, format the string using html tags. For example the title might look like:

<html>Enter <b>at least</b> 6 characters</html>
If you use formatted text, it should be accessible and make sense to the user if formatting wasn't there.
Default Value:
  • when the option is not set, the element's title attribute is used as its initial value if it exists.
Inherited From:
Source:
Examples

Initialize the component with the title option:

<!-- Foo is InputText, InputNumber, Select, etc. -->
<input id="username" type="text" data-bind="
   ojComponent: {component: 'ojFoo', title : 'enter at least 3 alphanumeric characters', 
                 pattern: '[a-zA-Z0-9]{3,}', value: ''}"/>

Initialize title option from html attribute 'title':

<!-- Foo is InputText, InputNumber, Select, etc. -->
<input id="username" type="text" value= "foobar" title="enter at least 3 alphanumeric characters" 
          pattern="[a-zA-Z0-9]{3,}"/>
$("#username").ojFoo({}); // Foo is InputText, InputNumber, Select, etc. // reading the title option will return "enter at least 3 alphanumeric characters" $("#username").ojFoo("option", "title"); // Foo is InputText, InputNumber, Select, etc.

translations :Object

A collection of translated resources from the translation bundle, or null if this component has no resources. Resources may be accessed and overridden individually or collectively, as seen in the examples.

If this component has (or inherits) translations, their documentation immediately follows this doc entry.

Default Value:
  • an object containing all resources relevant to the component and all its superclasses, or null if none
Inherited From:

Examples

Initialize the component, overriding some translated resources. This syntax leaves the other translations intact at create time, but not if called after create time:

// Foo is InputDate, InputNumber, etc.

                                           someOtherKey: "someOtherValue" } });

Get or set the translations option, after initialization:

// Get one.  (Foo is InputDate, InputNumber, etc.)
var value = $( ".selector" ).ojFoo( "option", "translations.someResourceKey" );

// Get all.  (Foo is InputDate, InputNumber, etc.)
var values = $( ".selector" ).ojFoo( "option", "translations" );

// Set one, leaving the others intact.  (Foo is InputDate, InputNumber, etc.)
$( ".selector" ).ojFoo( "option", "translations.someResourceKey", "someValue" );

// Set many.  Any existing resource keys not listed are lost.  (Foo is InputDate, InputNumber, etc.)
$( ".selector" ).ojFoo( "option", "translations", { someKey: "someValue",
                                                    someOtherKey: "someOtherValue" } );

value :Array

The value of the select component. The data type of value is array. For a single select, only the first element of the array is used.
Default Value:
  • When the value option is not set, the first option is used as its initial value if it exists.
Source:
Examples

Initialize the select with the value option specified:

$(".selector").ojSelect({"value": ["option1"]});

Get or set the value option, after initialization:

// Getter: returns value
$(".selector").ojSelect("option", "value");
// Setter: sets value with array containing "option1"
$(".selector").ojSelect("option", "value", ["option1"]);

Non-public Fields

Note: Extending JET components is not currently supported. Thus, non-public fields are for internal use only.

<protected> _AfterSetOptionRequired

Performs post processing after required option is set by taking the following steps. - if component is invalid and has messgesShown -> required: false/true -> clear component errors; run full validation with UI value (we don't know if the UI error is from a required validator or something else);
  - if there are validation errors, then value not pushed to model; messagesShown is updated
  - if no errors result from the validation, push value to model; author needs to listen to optionChange(value) to clear custom errors.
- if component is invalid and has messagesHidden -> required: false -> clear component errors; no deferred validation is run.
- if component has no error -> required: true -> run deferred validation (we don't want to flag errors unnecessarily)
- messagesCustom is never cleared

Binding Attributes

Binding attributes are similar to component options, but are exposed only via the ojComponent binding.

invalidComponentTracker :oj.InvalidComponentTracker

When this attribute is bound to an observable, the framework pushes an object of type oj.InvalidComponentTracker onto the observable. The object itself tracks the validity of a group of editable components.

When this attribute is present, the binding registers a listener for the optionChange event. This event is fired by JET editable components whenever its validity changes (i.e. when messagesShown or messagesHidden options change). When the event is fired, the listener determines the current validity of the component and updates the tracker.

The observable bound to this attribute is often used with multiple component binding declarations as shown in the example below.

This attribute is only exposed via the ojComponent binding, and is not a component option.

  • null

Examples

Track validity of multiple components using a single observable bound to the invalidComponentTracker attribute:

<input id="username" type="text" name="username" required 
  data-bind="ojComponent: {component: 'ojInputText', value: userName, 
                           invalidComponentTracker: tracker}">

<input id="password" type="password" name="password" required 
  data-bind="ojComponent: {component: 'ojInputPassword', value: password, 
                           invalidComponentTracker: tracker}"/>
  
// ViewModel that defines the tracker observable
<script>
function MemberViewModel() 
{ 
  var self = this;
  
  self.tracker = ko.observable();
  
  self.userName = ko.observable();   
  self.password = ko.observable();
  
  self.focusOnFirstInvalid = function() 
  {
     var trackerObj = ko.utils.unwrapObservable(self.tracker);
     if (trackerObj !== undefined)
     {
       // make sure the trackerObj is an oj.InvalidComponentTracker 
       // before calling methods on it.
       if (trackerObj instanceof oj.InvalidComponentTracker)
       {
          // showMessages first
          // (this will show any hidden messages, if any)
          trackerObj.showMessages();
          // focusOnFirstInvalid will focus on the first component
          // that is invalid, if any.      
          trackerObj.focusOnFirstInvalid();
        }
      }
    }
}
</script>

Use tracker property invalid to disable button:

// button is disabled if there are components currently showing errors
<button type="button" data-bind="ojComponent: {component: 'ojButton', label: 'Submit',
                                               disabled: tracker()['invalidShown']}">

Sub-ID's

Each subId locator object contains, at minimum, a subId property, whose value is a string that identifies a particular DOM node in this component. It can have additional properties to further specify the desired node. See getNodeBySubId and getSubIdByNode methods for more details.

Properties:
Name Type Description

              Methods

              getNodeBySubId(locator) → {Element|null}

              Returns the component DOM node indicated by the locator parameter.

              If the locator or its subId is null, then this method returns the element on which this component was initialized.

              If a non-null subId is provided but no corresponding node can be located, then this method returns null.

              This method is intended for use in test automation only, and should not be used in a production environment.

              Parameters:
              Name Type Description
              locator Object An Object containing, at minimum, a subId property, whose value is a string that identifies a particular DOM node in this component.

              If this component has (or inherits) any subIds, then they are documented in the Sub-ID's section of this document.

              Some components may support additional fields of the locator Object, to further specify the desired node.

              option(optionName, value) → {Object|undefined}

              This method has several overloads, which get and set component options and their fields. The functionality is unchanged from that provided by JQUI. See the examples for details on each overload.

              Parameters:
              Name Type Argument Description
              optionName string | Object <optional>
              the option name (string, first two overloads), or the map (Object, last overload). Omitted in the third overload.
              value Object <optional>
              a value to set for the option. Second overload only.

              Returns:
              The getter overloads return the retrieved value(s). When called via the public jQuery syntax, the setter overloads return the object on which they were called, to facilitate method chaining.
              Type
              Object | undefined
              Examples

              First overload: get one option:

              This overload accepts a (possibly dot-separated) optionName param as a string, and returns the current value of that option.

              var isDisabled = $( ".selector" ).ojFoo( "option", "disabled" ); // Foo is Button, Menu, etc.
              
              // For object-valued options, dot notation can be used to get the value of a field or nested field.
              var startIcon = $( ".selector" ).ojButton( "option", "icons.start" ); // icons is object with "start" field

              Second overload: set one option:

              This overload accepts two params: a (possibly dot-separated) optionName string, and a new value to which that option will be set.

              $( ".selector" ).ojFoo( "option", "disabled", true ); // Foo is Button, Menu, etc.
              
              // For object-valued options, dot notation can be used to set the value
              // of a field or nested field, without altering the rest of the object.
              $( ".selector" ).ojButton( "option", "icons.start", myStartIcon ); // icons is object with "start" field

              Third overload: get all options:

              This overload accepts no params, and returns a map of key/value pairs representing all the component options and their values.

              var options = $( ".selector" ).ojFoo( "option" ); // Foo is Button, Menu, etc.

              Fourth overload: set one or more options:

              This overload accepts a single map of option-value pairs to set on the component. Unlike the first two overloads, dot notation cannot be used.

              $( ".selector" ).ojFoo( "option", { disabled: true, bar: 42 } ); // Foo is Button, Menu, etc.

              #refresh()

              Refreshes the visual state of the select. JET components require a refresh() or re-init after the DOM is programmatically changed underneath the component.

              This method does not accept any arguments.

              reset()

              Resets the component by clearing all messages options - messagesCustom, messagesHidden and messagesShown, and updates the component's display value using the option value. User entered values will be erased when this method is called.

              Takes all hidden messages that are in the messagesHidden option and moves them to messagesShown option. If there were no messages in messagesHidden then this method simply returns.

              To view messages user has to set focus on the component.

              An optionChange event is triggered on both messagesHidden and messagesShown options.

              <protected, static> _GetContentElement() → {jQuery}

              Returns the jquery element that represents the content part of the component. This is usually the component that user sets focus on (tabindex is set 0) and where aria attributes like aria-required, aria-labeledby etc. are set. This is also the element where the new value is updated. Usually this is the same as the _GetMessagingLauncherElement.

              <protected, static> _GetDefaultStyleClass() → {string}

              Returns the default styleclass for the component. Currently this is used to pass to the _ojLabel component, which will append -label and add the style class onto the label. This way we can style the label specific to the input component. For example, for inline labels, the radioset/checkboxset components need to have margin-top:0, whereas all the other inputs need it to be .5em. So we'll have a special margin-top style for .oj-label-inline.oj-radioset-label All input components must override

              <protected, static> _GetMessagingLauncherElement() → {Object}

              Returns the messaging launcher element i.e., where user sets focus that triggers the popup. Usually this is the element input or select that will receive focus and on which the popup for messaging is initialized.

              <protected> _AfterCreate()

              The value option alone is initialized here since it requires the component to be fully created. Calling this.options.value before this method does not guarantee the correct value to be returned.

              <protected> _AfterCreateEvent()

              This method is called after the create event is fired. Components usually should not override this method, as it is rarely correct to wait until after the create event to perform a create-time task.

              An example of a correct usage of this method is Dialog's auto-open behavior, which needs to happen after the create event.

              Only behaviors (like Dialog auto-open behavior) should occur in this method. Component initialization must occur earlier, before the create event is fired, so that create listeners see a fully inited component.

              Overrides of this method should call this._super first.

              Do not confuse this method with the _AfterCreate method, which is more commonly used.

              <protected> _focusable(options)

              Sets JET's "focus" CSS classes when the element is focused and removes them when focus is lost.

              The oj-focus class is set on all focuses.

              Some components additionally have an oj-focus-highlight class, which applies a focus indicator that is appropriate on a subset of the occasions that oj-focus is appropriate. Those components should pass true for the applyHighlight param, in which case the oj-focus-highlight class is set if appropriate given the current focus highlight policy.

              Focus highlight policy

              The focus highlight policy supports the 3 values listed below. By default, it is retrieved from the $focusHighlightPolicy SASS variable, shared by many components and patterns. Components with different needs, including those exposing a component-specific SASS variable or other API for this, should see the getFocusHighlightPolicy parameter below. Valid focus highlight policies:

              Policy Description
              "nonPointer" Indicates that the component should apply the oj-focus-highlight class only for focuses not resulting from pointer (touch or mouse) interaction. (In the built-in themes, the SASS variable defaults to this value.)
              "all" Indicates that the component should apply the class for all focuses.
              "none" Indicates that the component should never apply the class, because the application has taken responsibility for applying the class when needed for accessibility.
              Toggling the classes

              Components that toggle these focus classes outside of this API must maintain the invariant that oj-focus-highlight is applied to a given element in a (not necessarily strict) subset of cases that oj-focus is applied to that element.

              Typically the specified element should be within the component subtree, in which case the classes will automatically be removed from the element when the component is destroyed, when its disabled option is set to true, and when _NotifyDetached() is called.

              As a minor exception, for components that wrap themselves in a new root node at create time, if the specified element is within the root node's subtree but not within the init node's subtree, then at destroy time only, the classes will not be removed, since destroy() is expected to remove such nodes.

              If the element is NOT in the component subtree, then the caller is responsible for removing the classes at the times listed above.

              Listeners

              If setupHandlers is not passed, or if setupHandlers is passed and uses _on to register its listeners as seen in the example, then the listeners are not invoked when the component is disabled, and the listeners are automatically cleaned up when the component is destroyed. Otherwise, the caller is responsible for ensuring that the disabled state is handled correctly, and removing the listeners at destroy time.

              Related API's

              Non-component internal callers should see oj.DomUtils.makeFocusable(). Per its JSDoc (unpublished; see the source), it has a couple of additional usage considerations.

              Parameters:
              Name Type Description
              options !Object | !jQuery This param can either be the element (convenience syntax for callers needing to specify only the element(s) that would otherwise have been passed as options.element) or an object supporting the following fields:
              Properties
              Name Type Argument Description
              element jQuery The element(s) to receive the oj-focus classes on focus. Required if setupHandlers not passed; ignored otherwise.
              applyHighlight boolean true if the oj-focus-highlight class should be applied when appropriate. false or omitted if that class should never be applied.
              afterToggle function(string) <nullable>
              Optional callback function called each time the focus classes have been toggled, after the toggle. The string "focusin" or "focusout" is passed, indicating whether the classes were added or removed. Components with consistency requirements, such as "oj-default must be applied iff no state classes such as oj-focus are applied," can enforce those rules in this callback.
              getFocusHighlightPolicy function() <nullable>
              Optional if applyHighlight is true; ignored otherwise. Components with a component-specific focus policy mechanism should pass a function that always returns one of the three valid values listed above, keeping in mind that this method can be called on every focus. See the example.
              recentPointer function() <nullable>
              Relevant iff applyHighlight is true and the focus highlight policy is "nonPointer"; ignored otherwise. Recent pointer activity is considered to have occurred if (a) a mouse button or finger has recently been down or up, or (b) this optional callback function returns true. Components wishing to additionally take into account (say) recent pointer movements can supply a function returning true if those movements have been detected, keeping in mind that this method can be called on every focus. See the example.
              setupHandlers function(function(!jQuery),function(!jQuery)) <nullable>
              Can be omitted by components whose focus classes need to be added and removed on focusin and focusout, respectively. Components needing to add/remove those classes in response to other events should specify this parameter, which is called once, immediately. See the examples.

              Examples

              Opt into the highlight behavior, and specify a function to be called every time the classes are toggled:

              var self = this;
              this._focusable({
                  'element': this.element, 
                  'applyHighlight': true, 
                  'afterToggle' : function() {
                      self._toggleDefaultClasses();
                  }
              });

              Arrange for mouse movement to be considered in addition to mouse/finger up/down. Also supply a component-specific focusHighlightPolicy:

              var self = this;
              this._focusable({
                  'element': someElement, 
                  'applyHighlight': true, 
                  'recentPointer' : function() {
                      // A timestamp-based approach avoids the risk of getting stuck in an inaccessible 
                      // state if (say) mouseenter is not followed by mouseleave for some reason.
                      var millisSincePointerMove = Date.now() - _myPointerMoveTimestamp;
                      var isRecent = millisSincePointerMove < myThreshold;
                      return isRecent;
                  },
                  'getFocusHighlightPolicy' : function() {
                      // Return the value of a component-specific SASS $variable, component option, or other 
                      // component-specific mechanism, either "all", "none", or "nonPointer".  SASS variables
                      // should be pulled into JS once statically on load, not per-instance or per-focus.
                  }
              });

              Add/remove the focus classes in response to events other than focusin/focusout:

              var self = this;
              this._focusable({
                  'applyHighlight': myBooleanValue, 
                  'setupHandlers': function( focusInHandler, focusOutHandler) {
                      self._on( self.element, {
                          // This example uses focus/blur listeners, which don't bubble, rather than the 
                          // default focusin/focusout (which bubble).  This is useful when one focusable  
                          // element is a descendant of another.
                          focus: function( event ) {
                              focusInHandler($( event.currentTarget ));
                          },
                          blur: function( event ) {
                              focusOutHandler($( event.currentTarget ));
                          }
                      });
                  }
              });

              Alternate usage of setupHandlers, which simply stashes the handlers so they can be called from the component's existing handlers:

              var self = this;
              this._focusable({
                  'applyHighlight': myBooleanValue, 
                  'setupHandlers': function( focusInHandler, focusOutHandler) {
                      self._focusInHandler = focusInHandler;
                      self._focusOutHandler = focusOutHandler;

              });

              <protected> _GetReadingDirection() → {string}

              Determines whether the component is LTR or RTL.

              Component responsibilities:

              • All components must determine directionality exclusively by calling this protected superclass method. (So that any future updates to the logic can be made in this one place.)
              • Components that need to know the directionality must call this method at create-time and from refresh(), and cache the value.
              • Components should not call this at other times, and should instead use the cached value. (This avoids constant DOM queries, and avoids any future issues with component reparenting (i.e. popups) if support for directional islands is added.)

              App responsibilities:

              • The app specifies directionality by setting the HTML "dir" attribute on the <html> node. When omitted, the default is "ltr". (Per-component directionality / directional islands are not currently supported due to inadequate CSS support.)
              • As with any DOM change, the app must refresh() the component if the directionality changes dynamically. (This provides a hook for component housekeeping, and allows caching.)
              Default Value:
              • "ltr"

              <protected> _GetSavedAttributes(element) → {Object|null}

              Gets the saved attributes for the provided element.

              If you don't override _SaveAttributes and _RestoreAttributes, then this will return null.

              If you override _SaveAttributes to call _SaveAllAttributes, then this will return all the attributes. If you override _SaveAttributes/_RestoreAttributes to do your own thing, then you may also have to override _GetSavedAttributes to return whatever you saved if you need access to the saved attributes.

              Parameters:

              <protected> _init()

              JET components should almost never implement this JQUI method. Please consult an architect if you believe you have an exception. Reasons:

              • This method is called at create time, after the create event is fired. It is rare for that to be the appropriate time to perform a create-time task. For those rare cases, we have the _AfterCreateEvent method, which is preferred over this method since it is called only at that time, not also at re-init time (see next).
              • This method is also called at "re-init" time, i.e. when the initializer is called after the component has already been created. JET has not yet identified any desired semantics for re-initing a component.

              <protected> _InitOptions(originalDefaults, constructorOptions)

              Called at component create time primarily to initialize options, often using DOM values. This method is called before _ComponentCreate is called, so components that override this method should be aware that the component has not been rendered yet. The element DOM is available and can be relied on to retrieve any default values.

              This method sets defaults for its options that have a DOM namesake. E.g., value, required, disabled etc. Subclasses can override this method to set their own defaults for these options. Example, the value option is often not set on this.element for components like radioset, which walk the sub-tree to determine the value.

              Parameters:
              Name Type Argument Description
              originalDefaults Object original default options defined on the widget and its ancestors

              <protected> _NotifyAttached()

              <protected> _NotifyContextMenuGesture(menu, event, eventType)

              When the contextMenu option is set, this method is called when the user invokes the context menu via the default gestures: right-click, Press & Hold, and Shift-F10. Components should not call this method directly.

              The default implementation simply calls this._OpenContextMenu(event, eventType). Overrides of this method should call that same method, perhaps with additional params, not menu.open().

              This method may be overridden by components needing to do things like the following:

              • Customize the launcher or position passed to _OpenContextMenu(). See that method for guidance on these customizations.
              • Customize the menu contents. E.g. some components need to enable/disable built-in commands like Cut and Paste, based on state at launch time.
              • Bail out in some cases. E.g. components with UX approval to use PressHoldRelease rather than Press & Hold can override this method to say if (eventType !== "touch") this._OpenContextMenu(event, eventType);. When those components detect the alternate context menu gesture (e.g. PressHoldRelease), that separate listener should call this._OpenContextMenu(), not this method (_NotifyContextMenuGesture()), and not menu.open().

              Components needing to do per-launch setup like the above tasks should do so in an override of this method, not in a beforeOpen listener or an _OpenContextMenu() override. This is discussed more fully here.

              Parameters:
              Name Type Description
              menu Object The JET Menu to open as a context menu. Always non-null.
              event Event What triggered the menu launch. Always non-null.

              <protected> _OpenContextMenu(event, eventType, openOptions, submenuOpenOptions, shallow)

              The only correct way for a component to open its context menu is by calling this method, not by calling Menu.open() or _NotifyContextMenuGesture(). This method should be called in two cases:

              • This method is called by _NotifyContextMenuGesture() and its overrides. That method is called when the baseComponent detects the default context menu gestures: right-click, Press & Hold, and Shift-F10.
              • Components with UX-approved support for alternate context menu gestures like PressHoldRelease should call this method directly when those gestures are detected.

              Components needing to customize how the context menu is launched, or do any per-launch setup, should do so in the caller of this method, (which is one of the two callers listed above), often by customizing the params passed to this method (_OpenContextMenu) per the guidance below. This setup should not be done in the following ways:

              • Components should not perform setup in a beforeOpen listener, as this can cause a race condition where behavior depends on who got their listener registered first: the component or the app. The only correct component use of a beforeOpen listener is when there's a need to detect whether something else launched the menu.
              • Components should not override this method (_OpenContextMenu), as this method is final. Instead, customize the params that are passed to it.

              Guidance on setting OpenOptions fields:

              Launcher:

              Depending on individual component needs, any focusable element within the component can be the appropriate launcher for this launch.

              Browser focus returns to the launcher on menu dismissal, so the launcher must at least be focusable. Typically a tabbable (not just focusable) element is safer, since it just focuses something the user could have focused on their own.

              By default (i.e. if openOptions is not passed, or if it lacks a launcher field), the component init node is used as the launcher for this launch. If that is not focusable or is suboptimal for a given component, that component should pass something else. E.g. components with a "roving tabstop" (like Toolbar) should typically choose the current tabstop as their launcher.

              The :focusable and :tabbable selectors may come in handy for choosing a launcher, e.g. something like this.widget().find(".my-class:tabbable").first().

              Position:

              By default, this method applies positioning that differs from Menu's default in the following ways: (The specific settings are subject to change.)

              • For mouse and touch events, the menu is positioned relative to the event, not the launcher.
              • For touch events, "my" is set to "start>40 center", to avoid having the context menu obscured by the user's finger.

              Usually, if position needs to be customized at all, the only thing that needs changing is its "of" field, and only for keyboard launches (since mouse/touch launches should almost certainly keep the default "event" positioning). This situation arises anytime the element relative to which the menu should be positioned for keyboard launches is different than the launcher element (the element to which focus should be returned upon dismissal). For this case, { "position": {"of": eventType==="keyboard" ? someElement : "event"} } can be passed as the openOptions param.

              Be careful not to clobber useful defaults by specifying too much. E.g. if you only want to customize "of", don't pass other fields like "my", since your value will be used for all modalities (mouse, touch, keyboard), replacing the modality-specific defaults that are usually correct. Likewise, don't forget the eventType==="keyboard" check if you only want to customize "of" for keyboard launches.

              InitialFocus:

              This method forces initialFocus to "menu" for this launch, so the caller needn't specify it.

              Parameters:
              Name Type Argument Description
              event Event What triggered the context menu launch. Must be non-null.
              eventType string "mouse", "touch", or "keyboard". Must be non-null. Passed explicitly since caller knows what it's listening for, and since events like contextmenu and click can be generated by various input modalities, making it potentially error-prone for this method to determine how they were generated.
              openOptions Object <optional>
              Options to merge with this method's defaults, which are discussed above. The result will be passed to Menu.open(). May be null or omitted. See also the shallow param.
              submenuOpenOptions Object <optional>
              Options to be passed through to Menu.open(). May be null or omitted.
              shallow boolean <optional>
              Whether to perform a deep or shallow merge of openOptions with this method's default value. The default and most commonly correct / useful value is false.
              • If true, a shallow merge is performed, meaning that the caller's position object, if passed, will completely replace this method's default position object.
              • If false or omitted, a deep merge is performed. For example, if the caller wishes to tweak position.of while keeping this method's defaults for position.my, position.at, etc., it can pass {"of": anOfValue} as the position value.

              The shallow param is n/a for submenuOpenOptions, since this method doesn't apply any defaults to that. (It's a direct pass-through.)

              <protected> _SaveAllAttributes(element)

              Saves all the element's attributes within an internal variable. _RestoreAllAttributes will restore the attributes from this internal variable.

              This method is final in JET. Subclasses can override _RestoreAttributes and call _RestoreAllAttributes.

              The JSON variable will be held as:

              [
                {
                "element" : element[i],
                "attributes" :
                  {
                    attributes[m]["name"] : {"attr": attributes[m]["value"]
                  }
                }
              ]

              <protected> _SetDisabledDom(node)

              Sets the disabled option onto the dom. Component subclasses can override this method to not do this in cases where it is invalid, like on a div (e.g., radioset's root dom element is a div).
              Parameters:
              Name Type Description
              node Object dom node

              <protected> _SetDisplayValue(displayValue)

              Called when the display value on the element needs to be updated. This method updates the (content) element value. Widgets can override this method to update the element appropriately.
              Parameters:
              Name Type Description
              displayValue String of the new string to be displayed

              <protected> _setOption(name, value, flags)

              Called (by the widget factory) when the option changes, this method responds to the change by refreshing the component if needed. This method is not called for the options passed in during the creation of the widget.
              Parameters:
              Name Type Description
              name string of the option
              value Object | string
              flags Object? optional flags. The following flags are currently supported:
              • changed - true if the caller wants to indicate the value has changed, so no comparison is necessary

              <protected> _SetPlaceholder(value)

              Sets the placeholder text on the content element by default. It sets the placeholder attribute on the element. Component subclasses can override this method to control where placeholder text gets set.
              Parameters:
              Name Type Description
              value string

              <protected> _SetPlaceholderOption(value)

              Sets the placeholder option with the value.
              Parameters:
              Name Type Description

              <protected> _SetRawValue(val, event)

              Convenience function to set the rawValue option. Called by subclasses
              Parameters:
              Name Type Description
              val String value to set rawValue to

              <protected> _SetRootAttributes()

              Reads the rootAttributes option, and sets the root attributes on the component's root DOM element. See rootAttributes for the set of supported attributes and how they are handled.

              <protected> _SetupResources()

              Sets up needed resources for this component, for example, add listeners. This is called during _create. _ReleaseResources will release resources help by this component, and is called during destroy.

              This base class default implementation does nothing.

              Component subclasses can opt in by overriding _SetupResources and _ReleaseResources.

              <protected> _SetValue(newValue, event, options) → {boolean}

              Runs full validation on the newValue (usually the display value) and sets the parsed value on the component if value passes basic checks and there are no validation errors.
              If the newValue is undefined or if it differs from the last saved displayValue this method skips validation and does not set value (same as ADF).
              Parameters:
              Name Type Argument Description
              newValue string | Object the ui value that needs to be parsed before it's set.
              event Object <optional>
              an optional event if this was a result of ui interaction. For user initiated actions that trigger a DOM event, passing this event is required. E.g., if user action causes a 'blur' event.
              options Object <optional>
              an Object literal that callers pass in to determine how validation gets run.
              Properties
              Name Type Argument Description
              doValueChangeCheck boolean <optional>
              if set to true compare newValue with last displayValue before running validation; if false, always run validation. E.g., set to false when validate() is called.
              doNotClearMessages boolean <optional>
              if set method will not clear all messages. This is provided for callers that may want to clear only some of the messages. E.g., when required option changes, it clears only component messages, not custom.
              validationMode number <optional>
              accepted values (defined in _VALIDATION_MODE) are:
              • FULL - the default and runs both the converter and all validators.
              • VALIDATORS_ONLY - runs all validators including the required validator is run.
              • REQUIRED_VALIDATOR_ONLY - runs just the required validator.

              <protected> _Validate(newValue, event, options) → {Object|string|undefined}

              Runs full validation on the value. If value fails basic checks (see _CanSetValue, or if value failed validation, this method returns false. Otherwise it returns true.

              Components should call this method if they know UI value has changed and want to set the new component value.

              Parameters:
              Name Type Argument Description
              newValue string | Object the actual value to be set. Usually this is the string display value
              event Object <optional>
              an optional event if this was a result of ui interaction. For user initiated actions that trigger a DOM event, passing this event is required. E.g., if user action causes a 'blur' event.
              options {doNotClearMessages:boolean,validationContext:number,validationMode:number} <optional>
              an Object literal that callers pass in to determine how validation gets run.
