Attributes

JET Custom Elements

JET components are implemented as custom HTML elements. In addition to the component attributes documented in this page, JET components also support standard HTML global attributes like id and aria-label.

The JET data binding syntax can be used to define both component and global attributes through the use of dynamically evaluated expressions. All attributes (component and global) support attribute-level binding by prefixing the attribute name with ":" (e.g. :id="[...]"). When using attribute-level binding, all expression values are treated as strings. Additionally, component attributes support property-level binding by using the attribute name directly with no ":" prefix. When using property-level binding, the expressions should evaluate to the types documented by the corresponding attributes. Property-level binding is strongly recommended over attribute-level binding for component attributes.

A detailed description of working with custom HTML elements can be found in: JET Custom Element Usage.


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

Version:
  • 5.0.0
Since:
  • 0.7
Module:
  • ojswitch

the oj-switch component enhances input element and manages the selection of Boolean values.

Touch End User Information

Target Gesture Action
Switch Thumb Tap Toggle switch value

Keyboard End User Information

Target Key Action
Switch Thumb Enter or Space Toggle switch value
Switch Thumb Tab In Set focus to the thumb. If hints, title or messages exist in a notewindow, pop up the notewindow.

Disabled items can not receive keyboard focus.

Accessibility

The component is accessible; it sets and maintains the appropriate aria- attributes, like aria-checked and aria-disabled.

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

See also the oj-focus-highlight discussion.

Styling

The following CSS classes can be applied by the page author as needed.

Class Description
oj-switch Top level switch class.
oj-focus-highlight Under normal circumstances this class is applied automatically. It is documented here for the rare cases that an app developer needs per-instance control.

The oj-focus-highlight class applies focus styling that may not be desirable when the focus results from pointer interaction (touch or mouse), but which is needed for accessibility when the focus occurs by a non-pointer mechanism, for example keyboard or initial page load.

The application-level behavior for this component is controlled in the theme by the $focusHighlightPolicy SASS variable; however, note that this same variable controls the focus highlight policy of many components and patterns. The values for the variable are:

  • nonPointer: oj-focus-highlight is applied only when focus is not the result of pointer interaction. Most themes default to this value.
  • all: oj-focus-highlight is applied regardless of the focus mechanism.
  • none: oj-focus-highlight is never applied. This behavior is not accessible, and is intended for use when the application wishes to use its own event listener to precisely control when the class is applied (see below). The application must ensure the accessibility of the result.

To change the behavior on a per-instance basis, the application can set the SASS variable as desired and then use event listeners to toggle this class as needed.

Label and Switch

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

Setting the Value Attribute

The value attribute should be Boolean. If the value attribute is undefined, then it is false.

Note: Application logic should not interact with the component's properties or invoke its methods until the BusyContext indicates that the component is ready for interaction.

Examples

Initialize the switch with no attributes specified:

<oj-switch></oj-switch>

Initialize the switch with some attributes specified:

<oj-switch value=true disabled=false></oj-switch>

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.

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.

Get or set the describedBy property after initialization:

// getter
var descById = myComp.describedBy;

// setter
myComp.describedBy = "someId";

disabled :boolean

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

Default Value:
  • false

Examples

Initialize the switch with disabled attribute:

<oj-switch disabled="true"></oj-switch>

Get or set the disabled property after initialization:

// Getter
var disabled = myComponent.disabled;

// Setter
myComponent.disabled = true;

display-options :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 helpInstruction.
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 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>

Properties:
Name Type Argument Description
converterHint Array.<('placeholder'|'notewindow'|'none')> | 'placeholder' | 'notewindow' | 'none' <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.<('notewindow'|'none')> | 'notewindow' | 'none' <optional>
supported values are 'notewindow', 'none'. To change the default value you can do this -
{'displayOptions: {'validatorHint': ['none']}}
messages Array.<('inline'|'notewindow'|'none')> | 'inline' | 'notewindow' | 'none' <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'}}
helpInstruction Array.<('notewindow'|'none')> | 'notewindow' | 'none' <optional>
supported values are 'notewindow', 'none'. To change the default value you can do this -
E.g. displayOptions='{"helpInstruction": "none"}'

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 display-options for one component:

// In this example, the display-options are changed from the defaults.
// The 'converterHint' is none, the 'validatorHint' is none and the 'helpInstruction' 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).
//
<oj-some-element display-options='{"converterHint": "none",
                                    "validatorHint": "none",
                                    "helpInstruction": "none"}'></oj-some-element>

Get or set the displayOptions property after initialization:

// Get one subproperty
var hint = myComp.displayOptions.converterHint;

// Set one, leaving the others intact. Use the setProperty API for 
// subproperties so that a property change event is fired.
myComp.setProperty("displayOptions.converterHint", "none");

// get all
var options = myComp.displayOptions;

// set all.  Must list every resource key, as those not listed are lost.
myComp.displayOptions = {converterHint: "none", validatorHint: "none", helpInstruction: "none"};

help :Object.<string, string>

Form component help information.

The properties supported on the help option are:

Properties:
Name Type Argument Description
instruction string <optional>
this represents advisory information for the component The default value is null.
Default Value:
  • {'help' : {'instruction': null}}
Since:
  • 0.7
Names
Item Name
Property help
Property change event helpChanged
Property change listener attribute (must be of type function) on-help-changed

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.

// Get one subproperty
var instr = myComp.help.instruction;

// Set one subproperty, leaving the others intact. Use the setProperty API for 
// subproperties so that a property change event is fired.
myComponent.setProperty('help.instruction', 'some new value');

// Get all
var values = myComponent.help;

// Set all.  Must list every resource key, as those not listed are lost.
myComponent.help = {
  instruction: 'some new value'
};

help-hints :Object.<string, string>

Represents hints for oj-form-layout element to render help information on the label of the editable component.

This is used only if the editable component is added as a direct child to an oj-form-layout element, and the labelHint property is also specified.

The helpHints object contains a definition property and a source property.

  • definition - hint for help definition text.
  • source - hint for help source URL.

Get or set the helpHints property after initialization:

// Get one
var value = myComponent.helpHints.definition;

// Set one, leaving the others intact. Always use the setProperty API for 
// subproperties rather than setting a subproperty directly.
myComponent.setProperty('helpHints.definition', 'some new value');

// Set all.  Must list every subproperty, as those not listed are lost.
myComponent.helpHints = {
    definition: 'some new value',
    source: 'some-new-url'
};

help-hints.definition :string

Hint for help definition text associated with the label.

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 help definition attribute.

See the help-hints attribute for usage examples.

help-hints.source :string

Hint for help source URL associated with the label.

If present, a help icon will render next to the label. 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. Pass in an encoded URL since we do not encode the URL.

See the help-hints attribute for usage examples.

label-hint :string

Represents a hint for oj-form-layout element to render a label on the editable component.

This is used only if the editable component is added as a direct child to an oj-form-layout element.

When labelHint is present it gives a hint to the oj-form-layout element to create an oj-label element for the editable component. When the labelHint property changes oj-form-layout element refreshes to display the updated label information.

Get or set the labelHint property after initialization:

// getter
var value = myComponent.labelHint;

// setter
myComponent.labelHint = 'some new value'

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.

See the Validation and Messages section for details on when the component clears messagesCustom; for example, when full validation is run.

Default Value:
  • []

// setter
myComp.messagesCustom = [{summary:"hello", detail:"detail", severity:oj.Message.SEVERITY_LEVEL.INFO}];

Set messagesCustom when there are cross-validation errors:

--- HTML ---
<oj-some-element messages-custom='{{messagesCustom}}'></oj-some-element> 

--- ViewModel code ---
self.messagesCustom = ko.observableArray([]);

// the app's function that gets called when the user presses the submit button
if (!myValidateCrossValidationFields())
{
  // the app adds a custom messages to the component and it is displayed right away
  var msgs = [];
  msgs.push({'summary':'Cross field error', 'detail':'Field 1 needs to be less than Field 2'});
  self.messagesCustom(msgs);
}
else
{
  // submit data to the server
}

readonly :boolean

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

translations :Object|null

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 the component does not contain any translatable resource, the default value of this attribute will be null. If not, an object containing all resources relevant to the component.

If this component has translations, their documentation immediately follows this doc entry.

};

(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 never set in this release of JET. It will be set in a future release.
"valid" string The component is valid

  // 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

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

Specify an ojAnimateEnd listener via the JavaScript property:

mySwitch.onOjAnimateEnd = listener;

Add an ojAnimateEnd listener via the addEventListener API:

mySwitch.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-switch on-oj-animate-start='[[listener]]'></oj-switch>

Specify an ojAnimateStart listener via the JavaScript property:

mySwitch.onOjAnimateStart = listener;

Add an ojAnimateStart listener via the addEventListener API:

mySwitch.addEventListener('ojAnimateStart', listener);

Methods

getProperty(property) → {*}

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
*
Example

Get a single subproperty of a complex property:

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

refresh() → {void}

Called when the DOM underneath the component changes requiring a re-render of the component. An example is when the id for the input changes.

Another time when refresh might be called is when the locale for the page changes. When it changes, attributes used by its converter and validator that are locale specific, its hints, messages and translations will be updated.

When refresh method is called, the component may take various steps such as clearing messages, running validation etc., based on the state it is in.

Steps Performed Always

  • The converter and validators used by the component are reset, and new converter and validator hints is pushed to messaging. E.g., notewindow displays the new hint(s).

Running Validation

  • if component is valid when refresh() is called, the display value is refreshed if component has a converter set.
  • if component is invalid and is showing messages when refresh() is called, then all component messages are cleared and full validation run using the display value on the component.
    • if there are validation errors, then value attribute is not updated and the error is shown.
    • if no errors result from the validation, the value attribute is updated; page author can listen to the onValueChanged event to clear custom errors.
  • if component is invalid and has deferred messages when refresh() is called, then all component messages are cleared and deferred validation is run.

Clearing Messages

  • If clearing messages only those created by the component are cleared.
  • messagesCustom attribute is not cleared.

Since:
  • 0.7
Returns:
Type
void
Example

Redraw the component element.
