updateCallbackDone property

JSPromise<JSAny?> get updateCallbackDone

The updateCallbackDone read-only property of the ViewTransition interface is a Promise that fulfills when the promise returned by the Document.startViewTransition method's callback fulfills, or rejects when it rejects.

updateCallbackDone is useful when you don't care about the success/failure of a same-document (SPA) view transition animation, and just want to know if and when the DOM is updated.

Note: In the case of a cross-document (MPA) view transition, the updateCallbackDone promise of the associated ViewTransition is automatically fulfilled.

Implementation

external JSPromise<JSAny?> get updateCallbackDone;
