Class ViewTransition

Namespace

CSharpToJavaScript.APIs.JS

Assembly

CSharpToJavaScript.dll

The ViewTransition interface of the {{domxref("View Transition API", "View Transition API", "", "nocode")}} represents an active view transition, and provides functionality to react to the transition reaching different states (e.g., ready to run the animation, or animation finished) or skip the transition altogether.

Remarks

This object type is made available in the following ways:

When a view transition is triggered by a startViewTransition() call (or a page navigation in the case of MPA transitions), a sequence of steps is followed as explained in The view transition process. This also explains when the different promises fulfill.

Properties

Finished

The finished read-only property of the
ViewTransition interface is a {{jsxref("Promise")}} that fulfills once the transition animation is finished, and the new page view is visible and interactive to the user.

[Value("finished")]
public Task<GlobalObject.Undefined> Finished { get; }

Property Value

Task<GlobalObject.Undefined>

A Promise.

Remarks

finished will only reject in the case of a same-document (SPA) transition, if the callback passed to StartViewTransition(Union20) throws or returns a promise that rejects. This would indicate that the new state of the page wasn't created.

If a transition animation fails to start or is skipped during the transition using SkipTransition(), the end state is still reached therefore finished will still fulfill.

Ready

The ready read-only property of the
ViewTransition interface is a {{jsxref("Promise")}} that fulfills once the pseudo-element tree is created and the transition animation is about to start.

[Value("ready")]
public Task<GlobalObject.Undefined> Ready { get; }

Property Value

Task<GlobalObject.Undefined>

A Promise.

Remarks

ready will reject if the transition cannot begin. This can be due to misconfiguration, for example, duplicate {{cssxref("view-transition-name")}}s, or if the callback passed to StartViewTransition(Union20) throws or returns a promise that rejects.

Types

[Value("types")]
public ViewTransitionTypeSet Types { get; set; }

Property Value

ViewTransitionTypeSet

UpdateCallbackDone

The updateCallbackDone read-only property of the
ViewTransition interface is a {{jsxref("Promise")}} that fulfills when the promise returned by the StartViewTransition(Union20) method's callback fulfills, or rejects when it rejects.

[Value("updateCallbackDone")]
public Task<GlobalObject.Undefined> UpdateCallbackDone { get; }

Property Value

Task<GlobalObject.Undefined>

A Promise.

Remarks

updateCallbackDone is useful when you don&apos;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.

Methods

SkipTransition()

The skipTransition() method of the
ViewTransition interface skips the animation part of the view transition, but doesn't skip running the associated view update.

[Value("skipTransition")]
public GlobalObject.Undefined SkipTransition()

Returns

GlobalObject.Undefined

undefined.
