The ariaDisabled property of the Element interface reflects the value of the aria-disabled attribute, which indicates that the element is perceivable but disabled, so it is not editable or otherwise operable.

A string with one of the following values:

"true"

The element and all focusable descendants are disabled, but perceivable, and their values cannot be changed by the user.

"false"

The element is enabled.

In this example the aria-disabled attribute on the element with an ID of saveChanges is set to "true" indicating that this input is currently disabled. Using ariaDisabled we update the value to "false".

<div id="saveChanges" tabindex="0" role="button" aria-disabled="true">Save</div>

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