The ariaReadOnly property of the Element interface reflects the value of the aria-readonly attribute, which indicates that the element is not editable, but is otherwise operable.

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:


The user cannot change the value of the element.


The user can set the value of the element.


In this example the aria-readonly attribute on the element with an ID of txtBoxInput is set to "true" indicating that this input is currently read only. Using ariaReadOnly 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-readonly="true"></div>
let el = document.getElementById('txtBoxInput');
console.log(el.ariaReadOnly); // "true"
el.ariaReadOnly = "false"
console.log(el.ariaReadOnly); // "false"
