The notification
read-only property of the NotificationEvent
interface returns the instance of the Notification

and data
attributes that allow you to store information for deferred use in the notificationclick
event.
Returns
A Notification
object.
Example
self.addEventListener('notificationclick', function(event) {
console.log('On notification click');
// Data can be attached to the notification so that you
// can process it in the notificationclick handler.
console.log('Notification Tag:', event.notification.tag);
console.log('Notification Data:', event.notification.data);
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('/');
}));
});
