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.
Note: Where possible use an HTML <input> element with type="text" or a <textarea> as these have built in semantics and do not require ARIA attributes.
A string 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"
