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.

JET Popup Component

Description: Themeable, WAI-ARIA-compliant popup that can display arbitrary content.

A JET popup can be created from custom element <oj-popup> syntax. This element will become the root - outer chrome of the popup. The content of the popup will be relocated under an element marked with the .oj-popup-content selector. Dynamic content can be inserted under the element identified by the .oj-popup-content selector. However, page developers are encouraged to create their own content element to anchor dynamic content changes versus using .oj-popup-content as the marker selector.

<oj-popup id="popup">
  <span class="mycontent">
    Hello World!
  </span class="mycontent">
</oj-popup>

The following is an example of dynamically changing the content of the popup defined above. 

var content = popup.querySelector( ".mycontent" );
content.textContent = "Hello Universe!";

Touch End User Information

Target Gesture Action
Outside popup or launcher Tap Close the popup.

Disabled items do not allow any touch interaction.

Keyboard End User Information

Target Key Action
Focus within Popup Tab or Shift + Tab Navigate the content of the popup. Close the open popup if there are no tab stops in the popup.
F6 Move focus to the launcher for a popup with modeless modality. Close the open popup if the modality is modal.
Esc Close the open popup.
Popup Launcher F6 Move focus to the first tab stop within the open popup. If there is not a tab stop within the content, focus is established on the popup.


Accessibility

For WAI-ARIA compliance, JET automatically adds role="tooltip" to the root popup dom element if not already specificed. This is not a component property but rather the standard html role attribute. Depending on how the popup is used in the page, the page developer should choose from the following:

  • "tooltip" defines contextual popup that displays a description for an element.
  • "dialog" defines an application window that is designed to interrupt the current processing of an application in order to prompt the user to enter information or require a response.
  • "alertdialog" defines type of dialog that contains an alert message, where initial focus goes to an element within the dialog.
The popup also adds the aria-describedby="popup-id" attribute to the assocaited launcher while the popup is open.

On platforms that support voice over mode (VO), the popup injects anchor tags "skip links" into the document for navigation. Skip links are not visible but read in VO mode. Two skip links are injected into the document when a popup is disclosed:
  • A close link, oj.ojPopup#translations.ariaCloseSkipLink, is injected as a sibling to the popup's content. Activation of this link will close the popup.
  • For cases where the popup doesn't steal focus when it's open, a content navigation skip link, oj.ojPopup#translations.ariaFocusSkipLink, is injected as a sibling to the launcher (first required argument of the open method). If the launcher selector targets a sub-element of the launcher, the skip link could be injected under the launcher, which can be problematic for oj-button as skip link activation will also activate the associated launcher.

One point often overlooked is making the gestures that launch a popup accessible. There are no constraints to what events a page developer might choose to trigger opening a popup. The choice should be accessible for screen reader users. Page developers should take care when using mouse events to trigger opening of a popup. This is especially important if the content of the popup can't be derived from other visible areas on the page. In cases that mouseover, mouseout, mouseenter, mouseleave and hover events are used to launch popups, there needs to be a keyboard functional equivalency.

See also the oj-focus-highlight discussion.

Reparenting

When popups are open, they will be reparented in the document and reparented back when closed. When open, the location of the popup within the document will be in context of how it's used. Popups open from other popups will be relocated in the document into the nearest parent popup's layer. The popups layer defines its z-index weight "stacking context". The ojPopup's layer is marked with the "oj-popup-layer" style. The context of opening is defined by the launcher argument passed to the open method. If not open from another popup, the popup will be reparented to a container in the document body. Popups of the same type are assigned the same z-index values. The layering between peer popups reflect the opening order. The popup that has active focus will be assigned a greater z-index value. This is applied to the popup's layer by way of the "oj-focus-within" pseudo selector applied with "oj-popup-layer" selector. The page author has control over z-index weights by way of the "oj-popup-layer" selector.

There are known caveats with this design. However, these scenarios are considered "bad use" based on our JET popup strategy.

  1. Events raised within the popup will not bubble up to the popup's original ancestors. Instead, listeners for popup events should be applied to either the popup's root element, or the document.
  2. Likewise, developers should not use CSS descendant selectors, or similar logic, that assumes that the popup will remain a child of its original parent.
  3. Popups containing iframes are problematic. The iframe elements "may" fire a HTTP GET request for its src attribute each time the iframe is reparented in the document.
  4. If an iframe is added to the popup's content, it must not be the first or last tab stop within the popup or keyboard and VoiceOver navigation will not remain within the popup.
  5. In some browsers, reparenting a popup that contains elements having overflow, will cause these overflow elements to reset their scrollTop.

Styling

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

Class Description Example
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.

 
<oj-popup class="oj-focus-highlight">
 <input id="blueopt" type="checkbox" value="blue">
 <label for="blueopt">Blue</label>
</oj-popup>

Event Handling

  • ojBeforeClose(event) - Triggered before a popup closes. Event can prevent closing the popup; However, there are cases the framework must veto, such as when the popup is destroyed.
  • ojBeforeOpen(event) - Triggered before a popup opens. Event can prevent opening the popup.
  • ojClose(event) - Triggered after the popup has closed.
  • ojFocus(event) - Triggered when initial focus is established on opening, depending on the value of the initalFocus property, or F6 focus toggle from the associated launcher.
  • ojOpen(event) - Triggered after the popup has been made visible.

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.

Slots

JET components that allow child content support slots. Please see the slots section of the JET component overview doc for more information on allowed slot content and slot types.

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 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.
