Element: ariaReadOnly property
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.
Value
A string with one of the following values:
Examples
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".
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-readonly="true"></div>
js
let el = document.getElementById("txtBoxInput");
console.log(el.ariaReadOnly); // "true"
el.ariaReadOnly = "false";
console.log(el.ariaReadOnly); // "false"
