ServiceWorkerMessageEvent.ServiceWorkerMessageEvent()

Deprecated

This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Important: In modern browsers, this property has been deprecated. Service worker messages will now use the MessageEvent interface, for consistency with other web messaging features.

The ServiceWorkerMessageEvent() constructor creates a new ServiceWorkerMessageEvent object instance.

Syntax

var mySWME = new ServiceWorkerMessageEvent(type, init);

Parameters

type
A DOMString that defines the type of the message event being created.
init Optional
An initialisation object, which should contain the following 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.

Examples

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

var mySWME = new ServiceWorkerMessageEvent('message', init);
