This value returns an empty string if the user clicked the notification somewhere other than an action button, or the notification does not have a button. The notification id is set during the creation of the Notification via the actions array attribute and can't be modified unless the notification is replaced.

Returns

A DOMString object.

Example

self.registration.showNotification("New articles available", {
  actions: [{action: "get", title: "Get now."}]
});

self.addEventListener('notificationclick', function(event) {
  event.notification.close();
  if (event.action === 'get') {
    synchronizeReader();
  } else {
    clients.openWindow("/reader");
  }
}, false);
