ServiceWorkerGlobalScope.onnotificationclick

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('/');
  }));
};
