Element: ariaDescription property

Baseline 2024
Newly available

Since ⁨March 2024⁩, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The ariaDescription property of the Element interface reflects the value of the aria-description attribute, which defines a string value that describes or annotates the current element.

Value

A string.

Examples

In this example the aria-description attribute on the element with an ID of close-button is set to the string "A longer description of the function of this element". Using ariaDescription we can update the value.

<button
  aria-label="Close"
  aria-description="A longer description of the function of this element"
  id="close-button">
  X
</button>
let el = document.getElementById("close-button");
console.log(el.ariaDescription); // "A longer description of the function of this element"
el.ariaDescription = "A different description";
console.log(el.ariaDescription); // "A different description"
