The ariaPressed property of the Element interface reflects the value of the aria-pressed attribute, which indicates the current "pressed" state of toggle buttons.

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.

In this example the aria-pressed attribute on the element with an ID of saveChanges is set to "false" indicating that this input is currently not pressed. Using ariaPressed we update the value to "true".

<div id="saveChanges" tabindex="0" role="button" aria-pressed="false">Save</div>

let el = document.getElementById("saveChanges");
console.log(el.ariaPressed); // "false"
el.ariaPressed = "true";
console.log(el.ariaPressed); // "true"
