The ariaHidden property of the Element interface reflects the value of the aria-hidden) attribute, which indicates whether the element is exposed to an accessibility API.

A string with one of the following values:

"true"

The element is hidden from the accessibility API.

"false"

The element is exposed to the accessibility API as if it were rendered.

undefined

The element's hidden state is determined by the user agent based on whether it is rendered.

In this example the aria-hidden attribute on the element with an ID of hidden is set to "true". Using ariaHidden we update the value to "false".

<div id="hidden" aria-hidden="true">Some things are better left unsaid.</div>

let el = document.getElementById("hidden");
console.log(el.ariaHidden); // true
el.ariaHidden = "false";
console.log(el.ariaHidden); // false
