SharedWorkerGlobalScope
The SharedWorkerGlobalScope
object (the SharedWorker
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 the complete list of functions available to workers.
Instance properties
This interface inherits properties from the WorkerGlobalScope
interface, and its parent EventTarget
.
-
The name that the
SharedWorker
was (optionally) given when it was created using theSharedWorker()
constructor. This is mainly useful for debugging purposes.
Instance properties inherited from WorkerGlobalScope
-
Returns the
CacheStorage
object associated with the current context. This object enables functionality such as storing assets for offline use, and generating custom responses to requests. -
Returns the
console
associated with the worker. -
Returns the
FontFaceSet
associated with the worker. -
Provides a mechanism for applications to asynchronously access capabilities of indexed databases; returns an
IDBFactory
object. -
Returns a boolean indicating whether the current context is secure (
true
) or not (false
). -
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. -
Returns the
WorkerNavigator
associated with the worker.WorkerNavigator
is a specific navigator object, mostly a subset of theNavigator
for browsing scopes, but adapted to workers. -
Returns the global object's origin, serialized as a string.
-
Returns the
Performance
object associated with the worker, which is a regular performance object, but with a subset of its properties and methods available. -
Returns the
Scheduler
object associated with the current context. This is the entry point for using the Prioritized Task Scheduling API. -
Returns an object reference to the
SharedWorkerGlobalScope
object itself.
Instance methods
This interface inherits methods from the WorkerGlobalScope
interface, and its parent EventTarget
.
-
Discards any tasks queued in the
SharedWorkerGlobalScope
's event loop, effectively closing this particular scope.
Inherited from WorkerGlobalScope
-
Decodes a string of data which has been encoded using base-64 encoding.
-
Creates a base-64 encoded ASCII string from a string of binary data.
-
Cancels the repeated execution set using
setInterval
. -
Cancels the repeated execution set using
setTimeout
. -
Writes a message to the console.
-
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');
-
Schedules the execution of a function every X milliseconds.
-
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.
connect
-
Fired on shared workers when a new client connects.
