Class WorkerGlobalScope

Namespace

Assembly

CSharpToJavaScript.dll

The WorkerGlobalScope interface of the Web Workers API is an interface representing the scope of any worker. Workers have no browsing context; this scope contains the information usually conveyed by Window objects — in this case event handlers, the console or the associated WorkerNavigator object. Each WorkerGlobalScope has its own event loop.

Remarks

This interface is usually specialized by each worker type: DedicatedWorkerGlobalScope for dedicated workers, SharedWorkerGlobalScope for shared workers, and ServiceWorkerGlobalScope for ServiceWorker. The self property returns the specialized scope for each context.

Constructors

WorkerGlobalScope()

public WorkerGlobalScope()

Properties

Location

The read-only location property of the WorkerGlobalScope interface 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.

[Value("location")]
public WorkerLocation Location { get; }

Property Value

WorkerLocation

A WorkerLocation object.

Remarks

Navigator

The navigator read-only property of the WorkerGlobalScope interface returns the WorkerNavigator associated with the worker. It is a specific navigator object, mostly a subset of the Navigator for browsing scopes, but adapted to workers.

[Value("navigator")]
public WorkerNavigator Navigator { get; }

Property Value

WorkerNavigator

A WorkerNavigator object.

Remarks

WorkerNavigator

[Value("onoffline")]
public EventHandlerNonNull Onoffline { get; set; }

Property Value

Ononline

[Value("ononline")]
public EventHandlerNonNull Ononline { get; set; }

Property Value

Onrejectionhandled

[Value("onrejectionhandled")]
public EventHandlerNonNull Onrejectionhandled { get; set; }

Property Value

EventHandlerNonNull

Onunhandledrejection

[Value("onunhandledrejection")]
public EventHandlerNonNull Onunhandledrejection { get; set; }

Property Value

EventHandlerNonNull

Self

The self read-only property of the WorkerGlobalScope interface returns a reference to the WorkerGlobalScope itself. Most of the time it is a specific scope like DedicatedWorkerGlobalScope, SharedWorkerGlobalScope, or ServiceWorkerGlobalScope.

[Value("self")]
public WorkerGlobalScope Self { get; }

Property Value

WorkerGlobalScope

A global scope object (differs depending on the type of worker you are dealing with, as indicated above).

Methods

ImportScripts(params Union95[])

WARNING

The parameters passed to this method represent the URLs of classic scripts to be imported into a worker.
APIs like this are known as injection sinks, and are potentially a vector for cross-site scripting (XSS) attacks.

[Value("importScripts")]
public GlobalObject.Undefined ImportScripts(params Union95[] urls)

Parameters

urls Union95[]

Returns

GlobalObject.Undefined

None (GlobalObject.Undefined).

Remarks

You can mitigate this risk by having a Content Security Policy (CSP) that restricts the locations from which scripts can be loaded, and by always assigning TrustedScriptURL objects instead of strings and enforcing trusted types.
See Security considerations for more information.

The importScripts() method of the WorkerGlobalScope interface synchronously imports one or more scripts into the scope of a classic worker (a worker constructed from a classic script).

Note that the method cannot be used in module workers, which instead load dependencies using import statements.
