Element: ariaOrientation 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 ariaOrientation property of the Element interface reflects the value of the aria-orientation attribute, which indicates whether the element's orientation is horizontal, vertical, or unknown/ambiguous.

Value

A string with one of the following values:

"horizontal"

The element is horizontal.

"vertical"

The element is vertical.

"undefined"

The element's orientation is unknown.

Examples

In this example the aria-orientation attribute on the element with an ID of handle_zoomSlider is set to "vertical". Using ariaOrientation we update the value to "horizontal".

html
<div
  id="handle_zoomSlider"
  role="slider"
  aria-orientation="vertical"
  aria-valuemin="0"
  aria-valuemax="17"
  aria-valuenow="14"
  tabindex="0">
  <span>11</span>
</div>
js
let el = document.getElementById("handle_zoomSlider");
console.log(el.ariaOrientation); // "vertical"
el.ariaOrientation = "horizontal";
console.log(el.ariaOrientation); // "horizontal"
