ElementInternals: ariaHasPopup property
Baseline 2023Newly available
Since October 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
TheariaHasPopup property of theElementInternals interface reflects the value of thearia-haspopup attribute, which indicates the availability and type of interactive popup element, such as menu or dialog, that can be triggered by an element.
Note:Setting aria attributes onElementInternals 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 theAccessibility Object Model explainer.
