class SharedWorkerGlobalScope

package js.html

extends WorkerGlobalScope › EventTarget

Available on HTML5

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.

Variables

read onlyname:String

The name that the SharedWorker was (optionally) given when it was created. This is the name that the SharedWorker.SharedWorker constructor can pass to get a reference to the SharedWorkerGlobalScope.

onconnect:Function

Is an EventHandler representing the code to be called when the connect event is raised — that is, when a MessagePort connection is opened between the associated SharedWorker and the main thread.

Inherited Variables

Defined by WorkerGlobalScope

read onlyconsole:Console

Returns the Console associated with the worker.

read onlyindexedDB:Factory

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

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.

onclose:Function

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

onerror:EitherType<Event, String> ‑> String ‑> Int ‑> Int ‑> Dynamic ‑> Bool

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 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.
