Element: <oj-select-one>

Slots

JET elements can have up to two types of child content:

• Any child element with a slot attribute will be moved into that named slot, e.g. <span slot='startIcon'>...</span>. All supported named slots are documented below. Child elements with unsupported named slots will be removed from the DOM.
• Any child element lacking a slot attribute will be moved to the default slot, also known as a regular child. This is documented under the "Default" heading below.

Default

The <oj-select-one> element accepts oj-options as children. See the oj-option doc for details about accepted children and slots.

Example

Initialize the select with child content specified:

<oj-select-one>
  <oj-option value="option1">Option1</oj-option>
</oj-select-one>

contextMenu

The contextMenu slot is set on the oj-menu within this element. This is used to designate the JET Menu that this 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 JET Menu specified in this slot.

The application can register a listener for the Menu's ojBeforeOpen 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 ojBeforeOpen 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.

Example

Initialize the component with a context menu:

<oj-some-element>
    <-- use the contextMenu slot to designate this as the context menu for this component -->
    <oj-menu slot="contextMenu" style="display:none" aria-label="Some element's context menu">
...
    </oj-menu>
</oj-some-element>

Attributes

(nullable) described-by :string

It is used to establish a relationship between this component and another element. Typically this is not used by the application developer, but by the oj-label custom element's code. One use case is where the oj-label custom element code writes described-by on its form component for accessibility reasons. To facilitate correct screen reader behavior, the described-by attribute is copied to the aria-describedby attribute on the component's dom element.

myComp.describedBy = "someId";

disabled :boolean

Whether the component is disabled. The default is false.

When the disabled property 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="{{currentValue}}" required disabled, 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 shown.
    • if no errors result from the validation, the value property is updated. Page authors can listen to the onValueChanged event 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 the valid property 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 the valid property is updated.
• when enabled component is disabled then no validation is run and the component appears disabled.

display-options :Object

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 converterHint, helpInstruction, messages, and validatorHint.
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.

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

A side note: help.instruction 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 help.instruction, you could do this:

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

help.instruction :string

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

When help.instruction is present it is by default displayed in the notewindow, or as determined by the 'helpInstruction' property set on the displayOptions attribute. When the help.instruction property changes the component refreshes to display the updated information.

JET takes the help instruction text and creates a notewindow with the text. The help instruction only shows up as a tooltip on mouse over, not on keyboard and not in a mobile device. So help instruction 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 help.instruction, format the string using html tags. For example the help.instruction might look like:

<oj-some-element help.instruction="<html>Enter <b>at least</b> 6 characters</html>"></oj-some-element>

If you use formatted text, it should be accessible and make sense to the user if formatting wasn't there.

messages-custom :Array.<Object>

List of messages an app would add to the component when it has business/custom validation errors that it wants the component to show. This allows the app to perform further validation before sending data to the server. When this option is set the message shows to the user right away. To clear the custom message, set messagesCustom back to an empty array.

Each message in the array is an object that duck types oj.Message. See oj.Message for details.

option-renderer :(function(Object)|null)

The renderer function that renders the content of each option. The function should return one of the following:

• An Object with the following property:
  • insert: HTMLElement - A DOM element representing the content of the option.
• undefined: If the developer chooses to manipulate the option content directly, the function should return undefined.

The option-renderer decides only how the options' content has to be rendered in the drop down. Once an option is selected from the drop down, what value has to be displayed in the in input field is decided by the label field in the data object. See options and options-keys for configuring option label and value.

The context parameter passed to the renderer contains the following keys:

Key	Description
component	A reference to the Select element.
parent	The parent of the data item. The parent is null for root node.
index	The index of the option, where 0 is the index of the first option. In the hierarchical case the index is relative to its parent.
depth	The depth of the option. The depth of the first level children under the invisible root is 0.
leaf	Whether the option is a leaf or a group.
data	The data object for the option.
parentElement	The option label element. The renderer can use this to directly append content.

         };

options :(Array.<(oj.Option|oj.Optgroup)>|oj.DataProvider.<oj.Option>)

The option items for the Select. This attribute can be used instead of providing a list of oj-option or oj-optgroup child elements of the Select element. This attribute accepts:

1. an array of oj.Options and/or oj.Optgroups.
   • Use oj.Option for a leaf option.
   • Use oj.Optgroup for a group option.
2. a data provider of oj.Options. This data provider must implement oj.DataProvider.
   • value in oj.Option must be the row key in the data provider.
   • A maximum of 15 rows will be displayed in the dropdown. If more than 15 results are available then users need to filter further. Please note that users can't filter further if render-mode is native.
   • If the data provider supports the filter criteria capability including the contains ($co) operator, JET Select will request the data provider to do filtering. Otherwise it will filter internally.

Examples

Initialize the Select with the options attribute specified:

The options array should contain objects with value and label properties:

var dataArray = [{value: 'option1', label: 'Option 1'}, 
                 {value: 'option2', label: 'Option 2', disabled: true}, 
                 {value: 'option3', label: 'Option 3'}];

Initialize the Select with a data provider and data mapping:

<oj-select-one options="[[dataProvider]]"></oj-select-one>

Data mapping can be used if data doesn't have value and label properties.

// actual field names are "id" and "name"
var dataArray = [
           {id: 'Id 1', name: 'Name 1'},
           {id: 'Id 2', name: 'Name 2'},
           {id: 'Id 3', name: 'Name 3'}];

// In mapfields, map "name" to "label" and "id" to "value"
var mapFields = function(item) {
  var data = item['data'];
  var mappedItem = {};
  mappedItem['data'] = {};
  mappedItem['data']['label'] = data['name'];
  mappedItem['data']['value'] = data['id'];
  mappedItem['metadata'] = {'key': data['id']};

}; 
var dataMapping = {'mapFields': mapFields};

var arrayDataProvider = new oj.ArrayDataProvider(dataArray, {keyAttributes: 'id'});
var dataProvider = new oj.ListDataProviderView(arrayDataProvider, {'dataMapping': dataMapping});

(nullable) options-keys :Object

Specify the key names to use in the options array.

Depending on options-keys means that the signature of the data does not match what is supported by the options attribute. When using Typescript, this would result in a compilation error.

Best practice is to use a oj.ListDataProviderView with data mapping as a replacement.

However, for the app that must fetch data from a REST endpoint where the data fields do not match those that are supported by the options attribute, you may use the options-keys with any dataProvider that implements oj.DataProvider interface.

render-mode :string

The render-mode attribute allows applications to specify whether to render select 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.
  • when using data provider a maximum of 15 rows will be displayed in the dropdown, users can't filter further.

The default 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.

required :boolean

Whether the element 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 attribute and the label associated with the element, are passed through to the options parameter of the createValidator method.

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

Running Validation

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

Clearing Messages

• Only messages created by the element are cleared.
• messages-custom property is not cleared.

This property set to false implies that a value is not required to be provided by the user. This is the default. This property set to true implies that 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 attribute.

Default Value:

• false

(readonly) valid :string

PREVIEW: This is a preview API. Preview APIs are production quality, but can be changed on a major version without a deprecation path.

The current valid state of the component. It is evaluated on initial render. It is re-evaluated

• after validation is run (full or deferred)
• when messagesCustom is updated, since messagesCustom can be added by the app developer any time.
• when showMessages() is called. Since showMessages() moves the hidden messages into messages shown, if the valid state was "invalidHidden" then it would become "invalidShown".
• when the required property has changed. If a component is empty and has required set, the valid state may be "invalidHidden" (if no invalid messages are being shown as well). If required property is removed, the valid state would change to "valid".

Note: New valid states may be added to the list of valid values in future releases. Any new values will start with "invalid" if it is an invalid state, "pending" if it is pending state, and "valid" if it is a valid state.

Supported Values:

Name	Type	Description
"invalidHidden"	string	The component has invalid messages hidden and no invalid messages showing. An invalid message is one with severity "error" or higher.
"invalidShown"	string	The component has invalid messages showing. An invalid message is one with severity "error" or higher.
"pending"	string	The component is waiting for the validation state to be determined. The "pending" state is set at the start of the convert/validate process.
"valid"	string	The component is valid

Supports writeback:

• true

Since:

• 4.2.0

Property	valid
Property change event	validChanged
Property change listener attribute (must be of type function)	on-valid-changed

Examples

Get valid attribute, after initialization:

// Getter:
var valid = myComp.valid;

Set the on-valid-changed listener so you can do work in the ViewModel based on the valid property:

<oj-some-element id='username' on-valid-changed='[[validChangedListener]]'>
</oj-some-element>
<oj-some-element id='password' on-valid-changed='[[validChangedListener]]'>
</oj-some-element>
<oj-button disabled='[[componentDisabled]]' on-click='[[submit]]'>Submit</oj-button>
-- ViewModel --
self.validChangedListener = function (event) {
  var enableButton;
  var usernameValidState;
  var passwordValidState;
  
  // update the button's disabled state.
  usernameValidState = document.getElementById("username").valid;
  passwordValidState = document.getElementById("password").valid;
  
  // this updates the Submit button's disabled property's observable based
  // on the valid state of two components, username and password.
  // It is up to the application how it wants to handle the �pending� state 
  // but we think that in general buttons don�t need to be 
  // enabled / disabled based on the "pending" state.
  enableButton = 
   (usernameValidState !== "invalidShown") &&
   (passwordValidState !== "invalidShown");
  self.componentDisabled(!enableButton);;
};

value :any

The value of the element. It supports any type. Select only accepts a value that's in the drop down list. Trying to set a new value that's not in the drop down list fails validation and the new value is not set.

If a value is specified before the data for the drop down list is available, then that value is set initially. When the data for the drop down list is available, the initially set value is validated. If it fails validation, the first option will be set as the value instead.

Default Value:

• When the value attribute is not set, the first option is used as its initial value if it exists.

Supports writeback:

• true

Property	value
Property change event	valueChanged
Property change listener attribute (must be of type function)	on-value-changed

Examples

Initialize the select with the value attribute specified:

<oj-select-one value="option1"></oj-select-one>

Get or set the value property after initialization:

// getter
var value = mySelect.value;

// setter
mySelect.value = "option1";

value-option :null|Object

The valueOption is similar to the value, but is an Object which contains both a value and display label. The value and valueOption are kept in sync. If initially both are set, the selected value in the value attribute has precedence.

Note: There may be a performance gain if the options attribute is a data provider and the valueOption is initially set then its label is used before the real data is fetched. If valueOption is not specified or the selected value is missing, then the label will be fetched from the data provider.

Properties:

Name	Type	Argument	Description
value	any		current value of JET Select
label	string	<optional>	display label of value above. If missing, String(value) is used.

Default Value:

• null

Supports writeback:

• true

Events

ojAnimateEnd

Triggered when a default animation has ended.

Properties:

All of the event payloads listed below can be found under event.detail.

Name	Type	Description
action	string	The action that triggers the animation. Supported values are: "inline-open" - when an inline message container opens or increases in size "inline-close" - when an inline message container closes or decreases in size "notewindow-open" - when a note window opens "notewindow-close" - when a note window closes
element	Element	The element being animated.

Since:

• 4.0.0

Examples

Define an event listener for the ojAnimateEnd event to add any processing after the end of "inline-open" animation:

var listener = function( event )
{
  // Check if this is the end of "inline-open" animation for inline message
  if (event.detail.action == "inline-open") {
    // Add any processing here
  }
};

Specify an ojAnimateEnd listener via the DOM attribute:

<oj-select-one on-oj-animate-end='[[listener]]'></oj-select-one>

Specify an ojAnimateEnd listener via the JavaScript property:

mySelectOne.onOjAnimateEnd = listener;

Add an ojAnimateEnd listener via the addEventListener API:

mySelectOne.addEventListener('ojAnimateEnd', listener);

ojAnimateStart

Triggered when a default animation is about to start on an element owned by the component.

The default animation can be cancelled by calling event.preventDefault, followed by a call to event.detail.endCallback. event.detail.endCallback should be called immediately after event.preventDefault if the application merely wants to cancel animation, or it should be called when the custom animation ends if the application is invoking another animation function. Failure to call event.detail.endCallback may prevent the component from working properly.

For more information on customizing animations, see the documentation of oj.AnimationUtils.

The default animations are controlled via the theme (SCSS) :

// default animations for "notewindow" display option
$noteWindowOpenAnimation: (effect: "zoomIn", transformOrigin: "#myPosition") !default;
$noteWindowCloseAnimation: (effect: "none") !default;

// default animations for "inline" display option
$messageComponentInlineOpenAnimation: (effect: "expand", startMaxHeight: "#oldHeight") !default;
$messageComponentInlineCloseAnimation: (effect: "collapse", endMaxHeight: "#newHeight") !default;

Properties:

All of the event payloads listed below can be found under event.detail.

Name	Type	Description
action	string	The action that triggers the animation. Supported values are: "inline-open" - when an inline message container opens or increases in size "inline-close" - when an inline message container closes or decreases in size "notewindow-open" - when a note window opens "notewindow-close" - when a note window closes
element	Element	The element being animated.
endCallback	function():void	If the event listener calls event.preventDefault to cancel the default animation, it must call the endCallback function when it finishes its own animation handling and any custom animation has ended.

Since:

• 4.0.0

Examples

Define an event listener for the ojAnimateStart event to override the default "inline-open" animation:

var listener = function( event )
  {
    // Change the "inline-open" animation for inline message
    if (event.detail.action == "inline-open") {
      // Cancel default animation
      event.preventDefault();
      // Invoke new animation and call endCallback when the animation ends
      oj.AnimationUtils.fadeIn(event.detail.element).then(event.detail.endCallback);
    }
  };

Define an event listener for the ojAnimateStart event to cancel the default "notewindow-close" animation:

var listener = function( event )
  {
    // Change the "notewindow-close" animation for note window
    if (ui.action == "notewindow-close") {
      // Cancel default animation
      event.preventDefault();
      // Call endCallback immediately to indicate no more animation
      event.detail.endCallback();
  };

Specify an ojAnimateStart listener via the DOM attribute:

<oj-select-one on-oj-animate-start='[[listener]]'></oj-select-one>

Specify an ojAnimateStart listener via the JavaScript property:

mySelectOne.onOjAnimateStart = listener;

Add an ojAnimateStart listener via the addEventListener API:

mySelectOne.addEventListener('ojAnimateStart', listener);

Methods

getProperty(property) → {any}

Retrieves a value for a property or a single subproperty for complex properties.

Parameters:

Name	Type	Description
property	string	The property name to get. Supports dot notation for subproperty access.

Since:

• 4.0.0

Returns:

Type

any

Example

Get a single subproperty of a complex property:

var subpropValue = myComponent.getProperty('complexProperty.subProperty1.subProperty2');

refresh()

Refreshes the visual state of the select. JET elements require a refresh() after the DOM is programmatically changed.

This method does not accept any arguments.

reset() → {void}

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

Since:

• 0.7

Returns:

Type

void

Example

Reset component

myComp.reset(); 

setProperties(properties) → {void}

Performs a batch set of properties.

Parameters:

Name	Type	Description
properties	Object	An object containing the property and value pairs to set.

Since:

• 4.0.0

Returns:

Type

void

Example

Set a batch of properties:

myComponent.setProperties({"prop1": "value1", "prop2.subprop": "value2", "prop3": "value3"});

setProperty(property, value) → {void}

Sets a property or a single subproperty for complex properties and notifies the component of the change, triggering a [property]Changed event.

Parameters:

Name	Type	Description
property	string	The property name to set. Supports dot notation for subproperty access.
value	any	The new value to set the property to.

Since:

• 4.0.0

Returns:

Type

void

Example

Set a single subproperty of a complex property:

myComponent.setProperty('complexProperty.subProperty1.subProperty2', "someValue");

showMessages() → {void}

Takes all deferred messages and shows them. It then updates the valid property; e.g., if the valid state was "invalidHidden" before showMessages(), the valid state will become "invalidShown" after showMessages().

If there were no deferred messages this method simply returns.

Since:

• 0.7

Returns:

Type

void

Example

Display all messages including deferred ones.

myComp.showMessages();

validate() → {Promise}

PREVIEW: This is a preview API. Preview APIs are production quality, but can be changed on a major version without a deprecation path.

1. All messages are cleared, including custom messages added by the app.
2. The implicit required validator is run first if the component is marked required.
3. At the end of validation if there are errors, the messages are shown. If there were no errors, then the value option is updated.

Returns:

Promise resolves to "valid" if the component passed validation. The Promise resolves to "invalid" if there were validation errors.

Type

Promise

Examples

Validate component using its current value.

myComp.validate();

Validate component and use the Promise's resolved state.

myComp.validate().then(
 function(result) {
   if(result === "valid")
   {
     submitForm();
   }
 });
