JET Rating Gauge Component

Rating gauge component for JET. Rating gauges are typically used to display or accept user feedback on a product or service.

This component should be bound to an HTML div element, and the SVG DOM that it generates should be treated as a black box, as it is subject to change. This component should not be extended.


<div data-bind="ojComponent: {component: 'ojRatingGauge', value: 4}"/>

Accessibility

The application is responsible for populating the shortDesc value in the component options object with meaningful descriptors when the component does not provide a default descriptor. Since component terminology for keyboard and touch shortcuts can conflict with those of the application, it is the application's responsibility to provide these shortcuts, possibly via a help popup.

Performance

Tracking Resize

By default, the component will track resizes and render at the new size. This functionality adds a small overhead to the initial render for simple components like gauges or spark charts, which become noticable when using large numbers of these simple components. To disable resize tracking, set trackResize to off. The application can manually request a re-render at any time by calling the refresh function.

Reading direction

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

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

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

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

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

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

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

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

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

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

      Examples

      Initialize a JET component with a context menu:

      // via recommended HTML5 syntax:
      <div id="myComponent" contextmenu="myMenu" data-bind="ojComponent: { ... }>
      
      // via JET initializer (less preferred) :
      // Foo is the component, e.g., InputText, InputNumber, Select, etc.
      $( ".selector" ).ojFoo({ "contextMenu": "#myMenu" });

      Get or set the contextMenu option, after initialization:

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

          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.

          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" );

                  Methods

                  getNodeBySubId(locator) → {Element|null}

                  Returns the component DOM node indicated by the locator parameter.

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

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

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

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

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

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

                  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 component.

                  Returns a promise that is resolved when the component is finished rendering. This can be used to determine when it is okay to call automation and other APIs on the component.

                  Add touch and mouse listeners to toggle oj-active class
                  Parameters:
                  Name Type Description
                  options !Object | !jQuery This parameter can either be the element (convenience syntax for callers needing to specify only the element(s) that would otherwise have been passed as options.element) or an object supporting the following fields:

                  Name Type Argument Description
                  element jQuery The element(s) to receive the oj-active class on active Required if afterToggle is specified.
                  afterToggle function(string) <nullable>
                  Optional callback function called each time the active classes have been toggled, after the toggle. The event.type string is passed and indicates whether the classes were added or removed. The active classes are added on "touchstart" or "mousedown" or "mouseenter" and the active classes are removed on "touchend" or "touchcancel" or "mouseup" or "mouseleave". Components with consistency requirements, such as "oj-default must be applied iff no state classes such as oj-active are applied," can enforce those rules in this callback.

                  <protected> _AfterCreate()

                  This method is called after _ComponentCreate, but before the create event is fired. The JET base component does tasks here that must happen after the component (subclass) has created itself in its override of _ComponentCreate. Notably, the base component handles the rootAttributes and contextMenu options here, since those options operate on the component root node, which for some components is created in their override of _ComponentCreate.

                  Subclasses should override this method only if they have tasks that must happen after a superclass's implementation of this method, e.g. tasks that must happen after the context menu is set on the component.

                  Overrides of this method should call this._super first.

                  <protected> _AfterCreateEvent()

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

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

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

                  Overrides of this method should call this._super first.

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

                  <protected> _ComponentCreate()

                  All component create-time initialization lives in this method, except the logic that specifically needs to live in _InitOptions, _AfterCreate, or _AfterCreateEvent, per the documentation for those methods. All DOM creation must happen here, since the intent of _AfterCreate, which is called next, is to contain superclass logic that must run after that DOM is created.

                  Overrides of this method should call this._super first.

                  Summary of create-time methods that components can override, in the order that they are called:

                  1. _InitOptions
                  2. _ComponentCreate (this method)
                  3. _AfterCreate
                  4. (The create event is fired here.)
                  5. _AfterCreateEvent

                  For all of these methods, the contract is that overrides must call this._super first, so e.g., the _ComponentCreate entry means baseComponent._ComponentCreate, then _ComponentCreate in any intermediate subclasses, then _ComponentCreate in the leaf subclass.

                  <protected> _focusable(options)

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

                  The oj-focus class is set on all focuses.

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

                  Focus highlight policy

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

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

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

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

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

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

                  Listeners

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

                  Related API's

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

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

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

                  this._focusable({
                      'element': this.element,

                  });

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

                  this._focusable({

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

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

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

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

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

                  Returns an object containing the top level options key and subkeys for deferred data options. 'root' is used for top level keys. For example, {'areaLayers': ['areaDataLayer/areas', 'areaDataLayer/markers'] indicates that we should check this.options['areaLayers'][i]['areaDataLayer']['areas'] and this.options['areaLayers'][i]['areaDataLayer']['markers']. To indicate a top level option, use the options key 'root', i.e. {'root': ['items']}.

                  Determines whether the component is LTR or RTL.

                  Component responsibilities:

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

                  App responsibilities:

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

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

                  Gets the saved attributes for the provided element.

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

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

                  <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.

                  Source:

                  <protected> _InitOptions(originalDefaults, constructorOptions)

                  This method is called before _ComponentCreate, at which point the component has not yet been rendered. Component options should be initialized in this method, so that their final values are in place when _ComponentCreate is called.

                  This includes getting option values from the DOM, where applicable, and coercing option values (however derived) to their appropriate data type if needed.

                  No work other than setting options should be done in this method. In particular, nothing should be set on the DOM until _ComponentCreate, e.g. setting the disabled DOM attribute from the disabled option.

                  A given option (like disabled) appears in the constructorOptions param iff the app set it in the constructor:

                  • If it appears in constructorOptions, it should win over what's in the DOM (e.g. disabled DOM attribute). If for some reason you need to tweak the value that the app set, then enable writeback when doing so: this.option('foo', bar, {'_context': {writeback: true, internalSet: true}}).
                  • If it doesn't appear in constructorOptions, then that option definitely is not bound, so writeback is not needed. So if you need to set the option (e.g. from a DOM attribute), use this.option('foo', bar, {'_context': {internalSet: true}}).

                  Overrides of this method should call this._super first.

                  <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.

                  <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.)
