Element.ariaModal

The ariaModal property of the Element interface reflects the value of the aria-modal attribute, which indicates whether an element is modal when displayed. Applying the aria-modal property to an element with role="dialog" replaces the technique of using aria-hidden on the background for informing assistive technologies that content outside a dialog is inert.

A DOMString with one of the following values:

"true"

The element is modal.

"false"

The element is not modal.

In this example the aria-modal attribute on the element with an ID of address-modal is set to "true" indicating that this is a modal dialog. Using ariaModal we update the value to "false".

<div role="dialog" id="address-modal" aria-labelledby="dialog1Title"
  aria-describedby="dialog1Desc" aria-modal="true"></div>

let el = document.getElementById('address-modal');
console.log(el.ariaModal); // "true"
el.ariaModal = "false"
console.log(el.ariaModal); // "false"
