Element.ariaRequired

The ariaRequired property of the Element interface reflects the value of the aria-required attribute, which indicates that user input is required on the element before a form may be submitted.

A DOMString with one of the following values:

"true"

Users need to provide input on an element before a form is submitted.

"false"

User input is not necessary to submit the form.

In this example the aria-required attribute on the element with an ID of txtBoxInput is set to "true" indicating that this input must be completed. Using ariaRequired we update the value to "false".

<div id="txtboxMultilineLabel">Enter the tags for the article</div>
<div role="textbox" id="txtBoxInput" contenteditable="true" aria-multiline="true"
  aria-labelledby="txtboxMultilineLabel" aria-required="true"></div>

let el = document.getElementById('txtBoxInput');
console.log(el.ariaRequired); // "true"
el.ariaRequired = "false"
console.log(el.ariaRequired); // "false"
