Element: ariaRequired property

{{APIRef("DOM")}} 

The ariaRequired property of the {{domxref("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 {{htmlelement("input")}}  element with type="text" or a {{htmlelement("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”.

<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"
