ariaModal property of the
ElementInternals interface reflects the value of the
aria-modal attribute, which indicates whether an element is modal when displayed.
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 ariaModal = ElementInternals.ariaModal; ElementInternals.ariaModal = ariaModal;
DOMString with one of the following values:
- The element is modal.
- The element is not modal.
In this example the value of
ariaModal is set to "true".
this.internals_.ariaModal = "true";
