This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The parameter passed into the onnotificationclick
handler, the NotificationEvent
interface represents a notification click event that is dispatched on the ServiceWorkerGlobalScope
of a ServiceWorker
.
This interface inherits from the ExtendableEvent
interface.

- Creates a new
NotificationEvent
object.

.
NotificationEvent.notification
Read only- Returns a
Notification
object representing the notification that was clicked to fire the event. NotificationEvent.action
