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.
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.
let ariaOrientation = ElementInternals.ariaOrientation; ElementInternals.ariaOrientation = ariaOrientation;
DOMString with one of the following values:
- The element is horizontal.
- The element is vertical.
- The element's orientation is unknown.
In this example the value of
ariaOrientation is set to "vertical".
this.internals_.ariaOrientation = "vertical";
