The SharedWorker interface represents a specific kind of worker that can be accessed from several browsing contexts, such as several windows, iframes or even workers. They implement an interface different than dedicated workers and have a different global scope, SharedWorkerGlobalScope.
- Value parameters:
- options
A DOMString specifying an identifying name for the SharedWorkerGlobalScope representing the scope of the worker, which is mainly useful for debugging purposes. Or, an object containing option properties that can set when creating the object instance.
- scriptURL
A DOMString representing the URL of the script the worker will execute. It must obey the same-origin policy.
- Constructor:
The SharedWorker constructor creates a SharedWorker object that executes the script at the specified URL.This script must obey the same-origin policy. If the URL has an invalid syntax or if the same-origin policy is violated, a DOMException of type SECURITY_ERR is thrown.
- Example:
var myWorker = new SharedWorker("aURL", name);- Companion:

Inherited methods
The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on. The event target may be an Element in a document, the Document itself, a Window, or any other object that supports events (such as XMLHttpRequest).
The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on. The event target may be an Element in a document, the Document itself, a Window, or any other object that supports events (such as XMLHttpRequest).
This implementation accepts a settings object of type EventListenerOptions.

Dispatches an Event at the specified EventTarget, invoking the affected EventListeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) apply to events dispatched manually with dispatchEvent().
