SharedWorkerGlobalScope
The SharedWorkerGlobalScope
object (the SharedWorker
global scope) is accessible through the self
(en-US) 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 the complete list of functions available to workers.
Properties
This interface inherits properties from the WorkerGlobalScope
interface, and its parent EventTarget
, and therefore implements properties from WindowTimers
(en-US), WindowBase64
, and WindowEventHandlers
.
SharedWorkerGlobalScope.name
(en-US) Lecture seule- The name that the
SharedWorker
was (optionally) given when it was created using theSharedWorker()
constructor. This is mainly useful for debugging purposes. SharedWorkerGlobalScope.applicationCache
Lecture seule- This property returns the
ApplicationCache
object for the worker (see Using the application cache).
Properties inherited from WorkerGlobalScope
WorkerGlobalScope.self
- Returns an object reference to the
DedicatedWorkerGlobalScope
object itself. WorkerGlobalScope.console
Lecture seule- Returns the
Console
associated with the worker. WorkerGlobalScope.location
Lecture seule- Returns the
WorkerLocation
associated with the worker.WorkerLocation
is a specific location object, mostly a subset of theLocation
for browsing scopes, but adapted to workers. WorkerGlobalScope.navigator
Lecture seule- Returns the
WorkerNavigator
(en-US) associated with the worker.WorkerNavigator
is a specific navigator object, mostly a subset of theNavigator
for browsing scopes, but adapted to workers. WorkerGlobalScope.performance
(en-US) Lecture seule- Returns the
Performance
object associated with the worker, which is a regular performance object, but with a subset of its properties and methods available.
Event handlers
This interface inherits event handlers from the WorkerGlobalScope
interface, and its parent EventTarget
, and therefore implements event handlers from WindowTimers
(en-US), WindowBase64
, and WindowEventHandlers
.
SharedWorkerGlobalScope.onconnect
- Is an
EventHandler
(en-US) representing the code to be called when theconnect
event is raised — that is, when aMessagePort
(en-US) connection is opened between the associatedSharedWorker
and the main thread.
Methods
This interface inherits methods from the WorkerGlobalScope
interface, and its parent EventTarget
, and therefore implements methods from WindowTimers
(en-US), WindowBase64
, and WindowEventHandlers
.
SharedWorkerGlobalScope.close()
(en-US)- Discards any tasks queued in the
SharedWorkerGlobalScope
's event loop, effectively closing this particular scope.
Inherited from WorkerGlobalScope
WorkerGlobalScope.close()
- Discards any tasks queued in the
WorkerGlobalScope
's event loop, effectively closing this particular scope. WorkerGlobalScope.dump()
- Allows you to write a message to stdout — i.e. in your terminal. This is the same as Firefox's
window.dump
, but for workers. WorkerGlobalScope.importScripts()
- Imports one or more scripts into the worker's scope. You can specify as many as you'd like, separated by commas. For example:
importScripts('foo.js', 'bar.js');
Implemented from other places
WindowBase64.atob()
- Decodes a string of data which has been encoded using base-64 encoding.
WindowBase64.btoa()
- Creates a base-64 encoded ASCII string from a string of binary data.
WindowTimers.clearInterval()
- Cancels the repeated execution set using
WindowTimers.setInterval()
(en-US). WindowTimers.clearTimeout()
(en-US)- Cancels the repeated execution set using
WindowTimers.setTimeout()
. WindowTimers.setInterval()
(en-US)- Schedules the execution of a function every X milliseconds.
WindowTimers.setTimeout()
- Sets a delay for executing a function.
Events
Listen to this event using addEventListener()
or by assigning an event listener to the oneventname
property of this interface.
