This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The data
read-only property of the PushEvent
interface returns a reference to a PushMessageData
object containing data sent to the PushSubscription
.
Syntax
var myPushData = PushEvent.data;
Value
A PushMessageData
object.
Examples
The following example takes data from a PushEvent and displays it on all of the service workers' clients.
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'); } }; });
