The ServiceWorkerGlobalScope.onpush
event of the ServiceWorkerGlobalScope
interface is fired whenever a push message is received by a service worker via a push server.
Syntax
ServiceWorkerGlobalScope.onpush = function(PushEvent) { ... } self.addEventListener('push', function(PushEvent) { ... })
Example
The following example takes data from a PushEvent
and displays it on all of the service worker's clients. The data payload of the push message is available in the event object's data
property (PushEvent.data
, which contains a PushMessageData
object.)
self.addEventListener('push', function(event) { if (!(self.Notification && self.Notification.permission === 'granted')) { return; } var data = {}; if (event.data) { data = event.data.json(); } var title = data.title || "Something Has Happened"; var message = data.message || "Here's something you might want to check out."; var icon = "images/new-notification.png"; var notification = new Notification(title, { body: message, tag: 'simple-push-demo-notification', icon: icon }); notification.addEventListener('click', function() { if (clients.openWindow) { clients.openWindow('https://example.blog.com/2015/03/04/something-new.html'); } }); });
