The activeViewTransition read-only property of the Element interface returns a ViewTransition instance representing the view transition currently active on an element. It provides a consistent way to access an active element-scoped view transition without needing to save a reference to it for later.

An element-scoped ViewTransition can also be accessed via the return value of Element.startViewTransition().

Value

A ViewTransition or null if the element has no active view transition.

Examples

Basic usage

This snippet shows how to use activeViewTransition to retrieve a reference to an ongoing view transition.

const myElement = document.querySelector(".my-element");

// ...

function handleVT() {
  const vt = myElement.startViewTransition(() => {
    updateDOMSomehow();
  });
}

// Returns a reference to vt if the transition is still ongoing
myElement.activeViewTransition;
