DedicatedWorkerGlobalScope extension type

The DedicatedWorkerGlobalScope object (the Worker global scope) is accessible through the WorkerGlobalScope.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.

Methods

addEventListener(String type, EventListener? callback, [JSAny options]) → void

The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.

inherited

atob(String data) → String

inherited

btoa(String data) → String

inherited

cancelAnimationFrame(int handle) → void

The cancelAnimationFrame() method of the DedicatedWorkerGlobalScope interface cancels an animation frame request previously scheduled through a call to DedicatedWorkerGlobalScope.requestAnimationFrame.

clearInterval([int id]) → void

inherited

clearTimeout([int id]) → void

inherited

close() → void

The close() method of the DedicatedWorkerGlobalScope interface discards any tasks queued in the DedicatedWorkerGlobalScope's event loop, effectively closing this particular scope.

createImageBitmap(ImageBitmapSource image, [JSAny optionsOrSx, int sy, int sw, int sh, ImageBitmapOptions options]) → JSPromise<ImageBitmap>

inherited

dispatchEvent(Event event) → bool

The dispatchEvent() method of the EventTarget sends an Event to the object, (synchronously) invoking the affected event listeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) also apply to events dispatched manually with dispatchEvent().

inherited

fetch(RequestInfo input, [RequestInit init]) → JSPromise<Response>

inherited

importScripts(String urls) → void

The importScripts() method of the WorkerGlobalScope interface synchronously imports one or more scripts into the worker's scope.

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

postMessage(JSAny? message, [JSObject optionsOrTransfer]) → void

The postMessage() method of the DedicatedWorkerGlobalScope interface sends a message to the main thread that spawned it.

queueMicrotask(VoidFunction callback) → void

inherited

removeEventListener(String type, EventListener? callback, [JSAny options]) → void

The removeEventListener() method of the EventTarget interface removes an event listener previously registered with EventTarget.addEventListener from the target. The event listener to be removed is identified using a combination of the event type, the event listener function itself, and various optional options that may affect the matching process; see Matching event listeners for removal.

inherited

reportError(JSAny? e) → void

inherited

requestAnimationFrame(FrameRequestCallback callback) → int

The requestAnimationFrame() method of the DedicatedWorkerGlobalScope interface tells the browser you wish to perform an animation frame request and call a user-supplied callback function before the next repaint.

setInterval(TimerHandler handler, JSAny? arguments, [int timeout]) → int

inherited

setTimeout(TimerHandler handler, JSAny? arguments, [int timeout]) → int

inherited

structuredClone(JSAny? value, [StructuredSerializeOptions options]) → JSAny?

inherited

toString() → String

A string representation of this object.

inherited

Operators

operator ==(Object other) → bool

The equality operator.
