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.

UserActivation.hasBeenActive Read only

Indicates whether the current window has sticky user activation.

UserActivation.isActive Read only

Indicates whether the current window has transient user activation.

Use UserActivation.isActive to check whether the user is currently interacting with the page (Transient activation).

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

Use UserActivation.hasBeenActive to check whether the user has ever interacted with the page (Sticky activation).

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