ElementInternals: ariaBusy property

{{APIRef("Web Components")}}

The ariaBusy property of the {{domxref("ElementInternals")}} interface reflects the value of the aria-busy attribute, which indicates whether an element is being modified, as assistive technologies may want to wait until the modifications are complete before exposing them to the user.

[!NOTE] Setting aria attributes on ElementInternals allows default semantics to be defined on a custom element. These may be overwritten by author-defined attributes, but ensure that default semantics are retained should the author delete those attributes, or fail to add them at all. For more information see the Accessibility Object Model explainer.

Value

A string with one of the following values:

• "true"
  • : The element is being updated.
• "false"
  • : There are no expected updates for the element.

Examples

In this example the value of ariaBusy is set to "true".

class CustomControl extends HTMLElement {
  constructor() {
    super();
    this.internals_ = this.attachInternals();
    this.internals_.ariaBusy = "true";
  }
  // …
}
