extends WorkerGlobalScope › EventTarget

@:native("DedicatedWorkerGlobalScope")

Available on js

The DedicatedWorkerGlobalScope object (the Worker global scope) is accessible through the self keyword. Some additional global functions, namespaces objects, and constructors, not typically associated with the worker global scope, but available on it, are listed in the JavaScript Reference. See also: Functions available to workers.

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.

`onmessage:Function`

Is an EventHandler representing the code to be called when the message event is raised. These events are of type MessageEvent and will be called when the worker receives a message from the document that started it (i.e. from the Worker.postMessage method.)

`onmessageerror:Function`

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

Methods

`close():Void`

Discards any tasks queued in the WorkerGlobalScope's event loop, effectively closing this particular scope.

`postMessage(message:Dynamic, ?transfer:Array<Dynamic>):Void`

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

Throws:

`null`	DOMError

Inherited Variables

`read onlycaches:CacheStorage`

`read onlycrypto:Crypto`

`read onlyindexedDB:Factory`

`read onlyisSecureContext:Bool`

`read onlylocation:WorkerLocation`

Returns the WorkerLocation associated with the worker. It is a specific location object, mostly a subset of the Location for browsing scopes, but adapted to workers.

`read onlynavigator:WorkerNavigator`

`onerror:(EitherType<Event, String>, String, Int, Int, Dynamic) ‑> Dynamic`

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

`onoffline:Function`

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

`ononline:Function`

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

`read onlyorigin:String`

`read onlyperformance:Performance`

Returns the Performance associated with the worker. It is a regular performance object, except that only a subset of its property and methods are available to workers.

`read onlyself:WorkerGlobalScope`

Returns a reference to the WorkerGlobalScope itself. Most of the time it is a specific scope like DedicatedWorkerGlobalScope, SharedWorkerGlobalScope or ServiceWorkerGlobalScope.
