Element.ariaSetSize
The ariaSetSize
property of the Element
interface reflects the value of the aria-setsize
attribute, which defines the number of items in the current set of listitems or treeitems.
Value
A DOMString
containing an integer.
Examples
In this example the aria-setsize
attribute on the element with an ID of tab-id
is set to "3", to inform a device that there are currently 3 tabs in the group. Using ariaSetSize
we update the value to "4".
<button role="tab" aria-selected="true" aria-setsize="3" aria-controls="tabpanel-id" id="tab-id">Tab label</button>
let el = document.getElementById('tab-id');
console.log(el.ariaSetSize); // 3
el.ariaSetSize = "4";
console.log(el.ariaSetSize); // 4
