The WindowOrWorkerGlobalScope mixin describes several features common to the Window and WorkerGlobalScope interfaces. Each of these interfaces can, of course, add more features in addition to the ones listed below.
Note: WindowOrWorkerGlobalScope is a mixin and not an interface; you can't actually create an object of type WindowOrWorkerGlobalScope.
Properties
These properties are defined on the WindowOrWorkerGlobalScope mixin, and implemented by Window and WorkerGlobalScope.
WindowOrWorkerGlobalScope.cachesLecture seule- Returns the
CacheStorageobject associated with the current context. This object enables functionality such as storing assets for offline use, and generating custom responses to requests. WindowOrWorkerGlobalScope.indexedDBLecture seule- Provides a mechanism for applications to asynchronously access capabilities of indexed databases; returns an
IDBFactoryobject. WindowOrWorkerGlobalScope.isSecureContextLecture seule- Returns a boolean indicating whether the current context is secure (
true) or not (false). WindowOrWorkerGlobalScope.originLecture seule- Returns the origin of the global scope, serialized as a string.
Methods
These properties are defined on the WindowOrWorkerGlobalScope mixin, and implemented by Window and WorkerGlobalScope.
WindowOrWorkerGlobalScope.atob()- Decodes a string of data which has been encoded using base-64 encoding.
WindowOrWorkerGlobalScope.btoa()- Creates a base-64 encoded ASCII string from a string of binary data.
WindowOrWorkerGlobalScope.clearInterval()- Cancels the repeated execution set using
WindowOrWorkerGlobalScope.setInterval(). WindowOrWorkerGlobalScope.clearTimeout()- Cancels the delayed execution set using
WindowOrWorkerGlobalScope.setTimeout(). WindowOrWorkerGlobalScope.createImageBitmap()- Accepts a variety of different image sources, and returns a
Promisewhich resolves to anImageBitmap. Optionally the source is cropped to the rectangle of pixels originating at (sx, sy) with width sw, and height sh. WindowOrWorkerGlobalScope.fetch()- Starts the process of fetching a resource from the network.
