UserActivation

The UserActivation interface allows querying information about a window's user activation state.

A user activation either implies that the user is currently interacting with the page, or has completed an interaction since page load. Typically, this is a click on a button or some other user interaction with the UI.

There are two kinds of window user activation states:

• Transient activation (user is currently interacting with the page) and
• Sticky activation (user has interacted at least once since page load).

See Features gated by user activation for more information and a list of APIs that require either sticky or transient user activation.

This API is only available in the window context and not exposed to workers.

if (navigator.userActivation.isActive) {
  // proceed to request playing media, for example
}

if (navigator.userActivation.hasBeenActive) {
  // proceed with auto-playing an animation, for example
}
