class WorkerGlobalScope

package js.html

extends EventTarget

extended by DedicatedWorkerGlobalScope, ServiceWorkerGlobalScope, SharedWorkerGlobalScope

Available on HTML5

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.

Variables

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.

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.

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

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