Variables

read onlyname:String

The name that the Worker was (optionally) given when it was created using the Worker.Worker constructor. This is mainly useful for debugging purposes.

onmessageerror:Function

Is an EventHandler representing the code to be called when the messageerror event is raised.

Methods

Sends a message — which can consist of any JavaScript object — to the parent document that first spawned the worker.

Throws:

null	DOMError
