Element.ariaPlaceholder

The ariaPlaceholder property of the Element interface reflects the value of the aria-placeholder attribute, which defines a short hint intended to aid the user with data entry when the control has no value.

A DOMString.

In this example the aria-placeholder attribute on the element with an ID of txtBoxInput has been set to a string. Using ariaPlaceholder we update the string to another value.

<div id="txtboxLabel">Enter your five-digit zipcode</div>
<div role="textbox" id="txtBoxInput" contenteditable="true" aria-placeholder="5-digit zipcode" aria-labelledby="txtboxLabel"></div>

let el = document.getElementById('txtBoxInput');
console.log(el.ariaPlaceholder); // "5-digit zipcode"
el.ariaPlaceholder = "12345"
console.log(el.ariaPlaceholder); // "12345"
