This is an experimental technologyCheck the Browser compatibility table carefully before using this in production.

The PushEvent() constructor creates a new PushEvent object. Note that the this constructor is exposed only to a service worker context.

Syntax

Parameters

type: A DOMString defining the type of PushEvent. This can be push or pushsubscriptionchange.
eventInitDict Optional: An options object containing any initialization data you want to populate the PushEvent object with. The options are:

data

The data you want the PushEvent to contain, if any. When the constructor is invoked, the PushEvent.data property of the resulting object will be set to a new PushMessageData object containing bytes extracted from the eventInitDict data member.

Example

var dataInit = {
  data : 'Some sample text'
}

var myPushEvent = new PushEvent('push', dataInit);

myPushEvent.data.text(); // should return 'Some sample text'
