ElementInternals: 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 ElementInternals
interface reflects the value of the aria-orientation
attribute, which indicates whether the element's orientation is horizontal, vertical, or unknown/ambiguous.
Note: Setting aria attributes on ElementInternals
allows default semantics to be defined on a custom element. These may be overwritten by author-defined attributes, but ensure that default semantics are retained should the author delete those attributes, or fail to add them at all. For more information see the Accessibility Object Model explainer.
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 value of ariaOrientation
is set to "vertical".
this.internals_.ariaOrientation = "vertical";
