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!";

Migration

Read about current Core Pack limitations to decide when to migrate.
Please make note of the following:

To migrate from oj-popup to oj-c-popup, you need to revise the import statement and references to oj-c-popup in your app.

In addition, please note the changes between the two components below.

position

The position property and its subproperties are replaced with a collection of new top-level attributes.

position.at, position.my

These properties are replaced with the placement property. The placement value defines the relative position of the popup to its anchor. For example, the following position specification


    position.at.horizontal="end"
    position.at.vertical="top"
    position.my.horizontal="start"
    position.my.vertical="bottom"

can be specified as


    placement="end-top-corner"
position.of

This property is replaced with the anchor attribute in oj-c-popup.

position.offset, position.collision

These properties are moved to the top-level as the offset and collision attributes.

open method

The open method is no longer supported. Visibility of the popup is controlled using the opened property in oj-c-popup. The launcher parameter is replaced with the new launcher attribute.

close method

The close method is no longer supported. Use opened="false" to close the popup.

isOpen method

The isOpen method is no longer supported. Use the opened property to determine the state of the popup.

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 non-modal popup root dom element, or role="dialog" to the modal popup root 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 when overriding the default values:

  • "tooltip" defines contextual popup that displays a description for an element. Although this is the default role for non-modal popups, it should only be used for popups that include simple textual content and no interactive elements. The "tooltip" role should never be used with modal popups.
  • "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. It is the default role for modal popups, but can (and should) be used for non-modal windows too, if the popup includes interactive content.
  • "alertdialog" defines type of popup that contains an alert message, where initial focus goes to an element within the popup.

The non-modal (modeless) popup with the "tooltip" role automatically adds the aria-describedby="popup-id" attribute to the associated launcher while the popup is open.

For popups with the "dialog" and "alertdialog" the page developer should consider adding the aria-haspopup="dialog" to the launcher element.

Depending on the aria role and popup content, the page developer may also need to set the aria-labelledby and (optionally) aria-describedby attributes on the oj-popup element in order to make the popup and its content accessible.

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 non-modal 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. The focus skip link is not injected for modal popups.

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.

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.


Usage

Signature:

interface PopupElement

Typescript Import Format
//To typecheck the element APIs, import as below.
import { PopupElement } from "ojs/ojpopup";

//For the transpiled javascript to load the element's module, import as below
import "ojs/ojpopup";

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.


Styling Classes

.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.
Example
<oj-popup class="oj-focus-highlight">
  <!-- Content -->
</oj-popup>

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.

Default

The <oj-popup> accepts any DOM elements in its Default slot but only tracks the validity state of any JET custom element descendents that contain the valid property.

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.

Deprecated:
Since Description
13.0.0 This web component no longer supports launching a context menu.
