ElementInternals: ariaLabel property

The ariaLabel property of the ElementInternals interface reflects the value of the aria-label attribute, which defines a string value that labels the current Element.

[!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.

Examples

In this example the value of ariaLabel is set to “close”.

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