ViewTransition: updateCallbackDone property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
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.
Value
A Promise.
Examples
// start new SPA view transition
const transition = document.startViewTransition(() => displayNewImage());
transition.updateCallbackDone.then(() => {
// Respond to the DOM being updated successfully
});
See Transitions as an enhancement for a useful example.
