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 ServiceWorkerGlobalScope.onnotificationclick property is an event handler called whenever the notificationclick event is dispatched on the ServiceWorkerGlobalScope object, that is when a user clicks on a displayed notification spawned by ServiceWorkerRegistration.showNotification().

Notifications created on the main thread or in workers which aren't service workers using the Notification() constructor will instead receive a click event on the Notification object itself.

Note: Trying to create a notification inside the ServiceWorkerGlobalScope using the Notification() constructor will throw an error.

Syntax

ServiceWorkerGlobalScope.onnotificationclick = function(NotificationEvent) { ... };

Example

self.onnotificationclick = function(event) {
  console.log('On notification click: ', event.notification.tag);
  event.notification.close();

  // This looks to see if the current is already open and
  // focuses if it is
  event.waitUntil(clients.matchAll({
    type: "window"
  }).then(function(clientList) {
    for (var i = 0; i < clientList.length; i++) {
      var client = clientList[i];
      if (client.url == '/' && 'focus' in client)
        return client.focus();
    }
    if (clients.openWindow)
      return clients.openWindow('/');
  }));
};
