ArrayBuffer 对象可以在不同的执行上下文之间传输,就像 Web Worker 或Service Worker 那样,使用结构化克隆算法。这可以通过在 Worker.postMessage() 或ServiceWorker.postMessage() 的调用中传入 ArrayBuffer 对象作为可转移对象来完成。在纯 JavaScript 中,也可以使用 transfer() 或transferToFixedLength() 方法来转移内存...

The ArrayBuffer object is used to represent a generic, fixed-length raw binary data buffer. You cannot directly manipulate the contents of an ArrayBuffer ; instead, you create one of the typed array objects or a DataView object which represents the buffe
ArrayBuffer.prototype.slice() Returns a newArrayBufferwhose contents are a copy of thisArrayBuffer's bytes frombegin, inclusive, up toend, exclusive. If eitherbeginorendis negative, it refers to an index from the end of the array, as opposed to from the beginning. ...
DataView 视图是一个可以从二进制 ArrayBuffer 对象中读写多种数值类型的底层接口,使用它时,不用考虑不同平台的字节序问题。 描述 字节序 多字节的数字格式在内存中的表示方式因机器架构而异——相关的解释请参阅字节序。DataView 访问器(accessor)提供了对如何访问数据的明确控制,而不管执行代码的计算机的字节序...
Blob.arrayBuffer() Returns a promise that resolves with an ArrayBuffer containing the entire contents of the Blob as binary data. Blob.bytes() Returns a promise that resolves with an Uint8Array containing the contents of the Blob. Blob.slice() Returns a new Blob object containing the data in...
