Element: ariaLevel 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.
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"
