PushEvent.PushEvent()

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

Syntax

JavaScript
var myPushEvent = new PushEvent(type, <span id="idl-def-PushEvent" class="idlInterface">eventInitDict</span>);

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

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

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

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