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.
SyntaxEdit
var myPushEvent = new PushEvent(type, eventInitDict);
Parameters
- type
- A
DOMString
defining the type ofPushEvent
. This can bepush
orpushsubscriptionchange
. - 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 thePushEvent
to contain, if any. When the constructor is invoked, thePushEvent.data
property of the resulting object will be set to a newPushMessageData
object containing bytes extracted from theeventInitDict data
member.
ExampleEdit
var dataInit = {
data : 'Some sample text'
}
var myPushEvent = new PushEvent('push', dataInit);
myPushEvent.data.text(); // should return 'Some sample text'
