, denied

this.onpush = function(event) { console.log(event.data); // From here we can write the data to IndexedDB, send it to any open // windows, display a notification, etc. } navigator.serviceWorker.register('serviceworker.js').then( function(serviceWorkerRegistration) { serviceWorkerRegistration.pushManager.subscribe().then( function(pushSubscription) { console.log(pushSubscription.endpoint); // The push subscription details needed by the application // server are now available, and can be sent to it using, // for example, an XMLHttpRequest. }, function(error) { // During development it often helps to log errors to the // console. In a production environment it might make sense to // also report information about errors back to the // application server. console.log(error); } ); });
