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