ServiceWorkerMessageEvent.ServiceWorkerMessageEvent()

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 ServiceWorkerMessageEvent() constructor creates a new ServiceWorkerMessageEvent object instance.

Parameters

  • data: The event's data — this can be any type.
  • origin: A DOMString that defines the origin of the corresponding service worker's environment settings object.
  • lastEventId: A DOMString that defines the last event ID of the event source.
  • source: The ServiceWorker or MessagePort that sent the message.
  • ports: An array containing the MessagePort objects connected to the channel sending the message.

var init = {
             data : 'hello message',
             source : MessagePortReference,
             ports : MessagePortListReference
           }
