WindowOrWorkerGlobalScope
O mixin WindowOrWorkerGlobalScope descreve vários recursos comuns às interfaces Window e WorkerGlobalScope. Cada uma dessas interfaces pode, obviamente, adicionar mais recursos além dos listados abaixo.
Nota: WindowOrWorkerGlobalScope é um mixin e não uma interface; você não pode atualmente criar um objeto do tipo WindowOrWorkerGlobalScope.
Properties
These properties are defined on the WindowOrWorkerGlobalScope mixin, and implemented by Window and WorkerGlobalScope (en-US).
WindowOrWorkerGlobalScope.caches(en-US) Somente leitura-
Returns the
CacheStorage(en-US) object associated with the current context. This object enables functionality such as storing assets for offline use, and generating custom responses to requests. WindowOrWorkerGlobalScope.indexedDB(en-US) Somente leitura-
Provides a mechanism for applications to asynchronously access capabilities of indexed databases; returns an
IDBFactoryobject. WindowOrWorkerGlobalScope.isSecureContext(en-US) Somente leitura-
Returns a boolean indicating whether the current context is secure (
true) or not (false). WindowOrWorkerGlobalScope.origin(en-US) Somente leitura-
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 (en-US).
WindowOrWorkerGlobalScope.atob()-
Decodes a string of data which has been encoded using base-64 encoding.
WindowOrWorkerGlobalScope.btoa()(en-US)-
Creates a base-64 encoded ASCII string from a string of binary data.
WindowOrWorkerGlobalScope.clearInterval()(en-US)-
Cancels the repeated execution set using
WindowOrWorkerGlobalScope.setInterval(). WindowOrWorkerGlobalScope.clearTimeout()-
Cancels the delayed execution set using
WindowOrWorkerGlobalScope.setTimeout()(en-US). WindowOrWorkerGlobalScope.createImageBitmap()(en-US)-
Accepts a variety of different image sources, and returns a
Promise(en-US) which resolves to anImageBitmap(en-US). 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.
WindowOrWorkerGlobalScope.setInterval()-
