{{APIRef("Web Components")}}

The ariaPressed property of the {{domxref("ElementInternals")}} interface reflects the value of the aria-pressed attribute, which indicates the current "pressed" state of toggle buttons.

[!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 pressed.
  • "false"
    • : The element supports being pressed but is not currently pressed.
  • "mixed"
    • : Indicates a mixed mode value for a tri-state toggle button.
  • "undefined"
    • : The element does not support being pressed.

Examples

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

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