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.


var ariaLevel = element.ariaLevel;
element.ariaLevel = ariaLevel


A DOMString containing an integer.


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".

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