Element: ariaRelevant property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since October 2023.

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

The ariaRelevant property of the Element interface reflects the value of the aria-relevant attribute, which indicates what notifications the user agent will trigger when the accessibility tree within a live region is modified. This is used to describe what changes in an aria-live region are relevant and should be announced.

Value

A string containing one or more of the following values, space separated:

"additions"

Additions of Element Nodes within the live region should be considered relevant.

"removals"

Deletion of Nodes from the live region should be considered relevant.

"text"

Changes to the textual content of existing nodes should be considered relevant.

"all"

Equivalent to "additions removals text".

Examples

In this example the aria-relevant attribute on the element with an ID of text is set to "all". Using ariaRelevant we update the value to "text".

html
<div
  id="clock"
  role="timer"
  aria-live="polite"
  aria-atomic="true"
  aria-relevant="all"></div>
js
let el = document.getElementById("clock");
console.log(el.ariaRelevant); // all
el.ariaRelevant = "text";
console.log(el.ariaRelevant); // text
