ElementInternals: ariaPressed property

Baseline 2023

Newly available

Since October 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The ariaPressed property of the 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
this.internals_.ariaPressed = "true";
