Element: ariaPosInSet 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 ariaPosInSet property of the Element interface reflects the value of the aria-posinset attribute, which defines an element's number or position in the current set of listitems or treeitems.
Value
A string containing an integer.
Examples
In this example the aria-posinset attribute on the element with an ID of article2 is set to "2". Using ariaPosInSet we update the value to "3".
html
<article id="article1" aria-posinset="1">…</article>
<article id="article2" aria-posinset="2">…</article>
js
let el = document.getElementById("article2");
console.log(el.ariaPosInSet); // "2"
el.ariaPosInSet = "3";
console.log(el.ariaPosInSet); // "3"
