Element: ariaRequired property

Baseline 2023
Newly available

Since October 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

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.

Value

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.

Examples

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".

html
<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>
js
let el = document.getElementById("txtBoxInput");
console.log(el.ariaRequired); // "true"
el.ariaRequired = "false";
console.log(el.ariaRequired); // "false"
