Element: ariaLevel property

Baseline 2023
Newly available

Since October 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The ariaLevel property of the Element interface reflects the value of the aria-level attribute, which defines the hierarchical level of an element within a structure.

Note: Where possible use an HTML h1 or other correct heading level as these have built in semantics and do not require ARIA attributes.

Value

A string containing an integer.

Examples

In this example the aria-level attribute on the element with an ID of main-heading is set to "1". Using ariaLevel we update the value to "2".

html
<div role="heading" id="main-heading" aria-level="1">
  This is a main page heading
</div>
js
let el = document.getElementById("main-heading");
console.log(el.ariaLevel); // "1"
el.ariaLevel = "2";
console.log(el.ariaLevel); // "2"
