The ariaBusy property of the Element interface reflects the value of the aria-busy attribute, which indicates whether an element is being modified, as assistive technologies may want to wait until the modifications are complete before exposing them to the user.


A string with one of the following values:


The element is being updated.


There are no expected updates for the element.


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

<div id="clock" role="timer" aria-live="polite" aria-atomic="true" aria-busy="false"></div>
let el = document.getElementById('clock');
console.log(el.ariaBusy); // false
el.ariaBusy = "true"
console.log(el.ariaBusy); // true
