oj. ojSwitch extends oj.editableValue

Version:
  • 1.2.0

Component JET Switch (ojSwitch) 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

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 component. For Switch, you should put an id on the input, and then set the for attribute on the label to be the input's id.

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 Option

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

Initializer

.ojSwitch(options)

Creates or re-initializes a JET Switch.
Parameters:
Name Type Argument Description
options Object <optional>
a map of option-value pairs to set on the component
Source:
Examples

Initialize the switch with no options specified:

$(".selector").ojSwitch();

Initialize the switch with some options specified:

$(".selector").ojSwitch({"value": true, "disabled": false});

Options

contextMenu :Object

JQ selector identifying 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.

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.

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

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., Menu, Button, 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

Disabled true disables the component and disables all the inputs/labels. Disabled false enables the component, and leaves the inputs disabled state as it is in the DOM.

Default Value:
  • false
Source:
Example

Initialize component with disabled option:

$(".selector").ojSwitch({"disabled": true});

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.

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 label or 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 because the help definition renders on title 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. The default value is null.
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

help definition text. See the top-level help option for details.

Default Value:

Example

Get or set the help.definition sub-option, after initialization:

// getter
var definitionText = $( ".selector" ).ojFoo( "option", "help.definition" );

// setter:

help.source :string

help source url. See the top-level help option for details.

Default Value:
  • null
Inherited From:

Example

Get or set the help.source sub-option, after initialization:

// getter
var helpSource = $( ".selector" ).ojFoo( "option", "help.source" );

// setter:
$( ".selector" ).ojFoo( "option", "help.source", "www.abc.com" );

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.
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.
Since:
  • 0.7
Inherited From:
Source:
See:
Example

Get messagesShown for the component:

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

<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.

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

Get messagesShown for the component:

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

readOnly :boolean

Whether the component is readOnly. The element's readOnly property is used as its initial value if it exists, when the option is not explicitly set. When neither is set, readOnly defaults to false.
Default Value:
  • false
Source:
Example

Initialize component with readOnly option:

$(".selector").ojSwitch({"readOnly": true});

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.

Default Value:
  • when the option is not set, the element's title attribute is used as its initial value if it exists.
Source:
Example

Initialize component with title option:

$(".selector").ojSwitch({"title": "My Switch"});

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:
Source:
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.
$( ".selector" ).ojFoo({ "translations": { someKey: "someValue",
                                           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" } );

validators :Array|undefined

List of validators used by component when performing validation. Each item is either an instance that duck types oj.Validator, or is an Object literal containing the properties listed below. Implicit validators created by a component when certain options are present (e.g. required option), are separate from validators specified through this option. At runtime when the component runs validation, it combines the implicit validators with the list specified through this option.

Hints exposed by validators are shown in the notewindow by default, or as determined by the 'validatorHint' property set on the displayOptions option.

When validators option changes due to programmatic intervention, the component may decide to clear messages and run validation, based on the current state it is in.

Steps Performed Always

  • The cached list of validator instances are cleared and new validator hints is pushed to messaging. E.g., notewindow displays the new hint(s).

Running Validation

  • if component is valid when validators changes, component does nothing other than the steps it always performs.
  • if component is invalid and is showing messages - messagesShown option is non-empty, when validators changes then all component messages are cleared and full validation run using the display value on the component.
    • 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.
  • if component is invalid and has deferred messages when validators changes, it does nothing other than the steps it performs always.

Clearing Messages

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

Properties:
Name Type Argument Description
type string the validator type that has a oj.ValidatorFactory that can be retrieved using the oj.Validation module. For a list of supported validators refer to oj.ValidatorFactory.
E.g., {validators: [{type: 'regExp'}]}
options Object <optional>
optional Object literal of options that the validator expects.
E.g., {validators: [{type: 'regExp', options: {pattern: '[a-zA-Z0-9]{3,}'}}]}
Inherited From:
Source:
Examples

Initialize the component with validator object literal:

// Foo is InputText, InputNumber, Select, etc.
$(".selector").ojFoo({
  validators: [{
    type: 'numberRange', 
    options : {
      hint: {min: 'Enter a value greater than {min}'}, 
      min: 100
    }
  }],
});

NOTE: oj.Validation.validatorFactory('numberRange') returns the validator factory that is used 
to instantiate a range validator for numbers.

Initialize the component with multiple validator instances:

var validator1 = new MyCustomValidator({'foo': 'A'}); 
var validator2 = new MyCustomValidator({'foo': 'B'});
// Foo is InputText, InputNumber, Select, etc.
$(".selector").ojFoo({
  value: 10, 
  validators: [validator1, validator2]
});

value :boolean

The state of the switch component (true/false).
Default Value:
  • false
Source:
Example

Initialize component (switch is ON) with value option:

$(".selector").ojSwitch({"value": true});

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.

Default Value:
  • null
Since:
  • 0.7
Inherited From:
Source:
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();
}
</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']}">

Events

destroy

Triggered before the component is destroyed. This event cannot be canceled; the component will always be destroyed regardless.

Inherited From:
Source:
Examples

Initialize component with the destroy callback

// Foo is Button, InputText, etc.
$(".selector").ojFoo({
  'destroy': function (event, data) {}
});

Bind an event listener to the destroy event

$(".selector").on({
  'ojdestroy': function (event, data) {
      window.console.log("The DOM node id for the destroyed component is : %s", event.target.id);
  };
});

optionChange

Triggered when any option changes. The event payload has the following properties:

Properties:
Name Type Description
event Event jQuery event object
data Object event payload
Properties
Name Type Description
option string the name of the option that changed.
previousValue Object an Object holding the previous value of the option. When previousValue is not a primitive type, i.e., is an Object, it may hold the same value as the value property.
value Object an Object holding the current value of the option.
optionMetadata Object information about the option that changed
Properties
Name Type Description
writeback string "shouldWrite" or "shouldNotWrite". For use by the JET writeback mechanism; 'shouldWrite' indicates that the value should be written to the observable.
Inherited From:
Source:
Examples

Initialize component with the optionChange callback

// Foo is Button, InputText, etc.
$(".selector").ojFoo({
  'optionChange': function (event, data) {}
});

Bind an event listener to the ojoptionchange event

$(".selector").on({
  'ojoptionchange': function (event, data) {
      window.console.log("option that changed is: " + data['option']);
  };
});

Methods

getNodeBySubId(locator) → {Element|null}

Return the subcomponent node represented by the documented locator attribute values.

If the locator is null or no subId string is provided then this method returns the element that this component was initalized with.

If a subId was provided but a subcomponent node cannot be located this method returns null.

Test authors should target switch sub elements using the following names:

  • oj-switch-track: span represents dom for switch track
  • oj-switch-thumb: span represents dom for switch thumb
Parameters:
Name Type Description
locator Object An Object containing at minimum a subId property whose value is a string, documented by the component, that allows the component to look up the subcomponent associated with that string. It contains:
  • component: optional - in the future there may be more than one component contained within a page element
  • subId: the string, documented by the component, that the component expects in getNodeBySubId to locate a particular subcomponent
Source:
Returns:
the subcomponent located by the subId string passed in locator, if found.
Type
Element | null

getSubIdByNode(node) → {Object|null}

Returns the subId locator for the given child DOM node.

If DOM node is null then method returns null.

If DOM node is not a child of the current component then method returns null.

Parameters:
Name Type Description
node Element child DOM node
Source:
Returns:
The subId for the DOM node, or null when none is found.
Type
Object | null

isValid() → {boolean}

Example

Check whether the component is valid:

var value = $(".selector").ojInputText("isValid");

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.
Inherited From:
Source:
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 switch

A refresh() or re-init is required when a switch is programatically changed.

Source:
Returns:
When called via the public jQuery syntax, this method returns the object on which it was called, to facilitate method chaining.
Example

Invoke the refresh method:

$( ".selector" ).ojSwitch( "refresh" );

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.
Since:
  • 0.7
Inherited From:
Source:
Returns:
When called via the public jQuery syntax, this method returns the object on which it was called, to facilitate method chaining.
Example

Reset component

$(selector).ojInputText("reset"); 

showMessages()

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.

Since:
  • 0.7
Inherited From:
Source:
Returns:
When called via the public jQuery syntax, this method returns the object on which it was called, to facilitate method chaining.
Example

Display all messages including deferred ones.

$(selector).ojInputText("showMessages");

validate() → {boolean}

Validates the component's display value using the converter and all validators registered on the component and updates the value option by performing the following steps.

  1. All messages are cleared, including custom messages added by the app.
  2. If no converter is present then processing continues to next step. If a converter is present, the UI value is first converted (i.e., parsed). If there is a parse error then the messagesShown option is updated and method returns false.
  3. If there are no validators setup for the component the value option is updated using the display value and the method returns true. Otherwise all validators are run in sequence using the parsed value from the previous step. The implicit required validator is run first if the component is marked required. When a validation error is encountered it is remembered and the next validator in the sequence is run.
  4. At the end of validation if there are errors, the messagesShown option is updated and method returns false. If there were no errors, then the value option is updated and method returns true.

    <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 checkboxset/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-checkboxset-label All input components must override

    <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.
    Inherited From:
    Source:

    <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.

    if disabled component is enabled then,
    - if there are no errors, run deferred validation. component could have been initialized with empty value and disabled.
    - if component is invalid and showing messages clear component error, grab UI value and run full validation.

    <protected> _AfterSetOptionRequired(option)

    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)

    <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> _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.
    Inherited From:
    Source:

    <protected> _InitOptions()

    <protected> _NotifyAttached()

    Notifies the component that its subtree has been connected to the document programmatically after the component has been created.

    Inherited From:
    Source:

    <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.
    eventType string "mouse", "touch", or "keyboard". Never null.

    Source:

    <protected> _NotifyDetached()

    Inherited From:

    Inherited From:
    Source:

    <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.)

    Throws:
    if unsupported attributes are supplied.

    <protected> _setupEvents()

    Binding events to the switch component
    Source:

    <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.

    Source:
    Returns:
    false if value was not set due to validation error.
    Type
    boolean
    Example

    Widget subclasses can use this convention to run full validation

    this._SetValue(value, event);

    <protected> _UnregisterChildNode()

    Remove all listener references that were attached to the element which includes _activeable, _focusable and hoverable.
    Inherited From:
    Source:

    <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.
    Properties
    Name Type Argument Description
    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.
    validationContext number <optional>
    the context this method was called. When not set it defaults to _VALIDATION_CONTEXT.USER_ACTION.
    validationMode number <optional>
    accepted values defined in _VALIDATION_MODE

    Returns:
    the parsed value or undefined if validation failed
    Type
    Object | string | undefined

    <protected> Focus() → {*}

    Sets focus on the element that naturally gets focus. For example, this would be the input element for input type components.
