javascript - Sending multiple array buffers to a Javascript web worker?

Question

yanni's answer shows how to send (transfer ownership) one buffer to a web worker: Using transferable objects from a Web Worker

How would I send multiple buffers (in an array) to a web worker (without copying)?

Answer 1

Worker#postMessage接受一组可转移对象，

var worker = new Worker("...");
var buffers = [new ArrayBuffer, new ArrayBuffer, new ArrayBuffer];
var message = {buffers: buffers};

worker.postMessage(message, buffers);

这是一个示例小提琴，http://jsfiddle.net/g247v/

Answer 2

这已经在其他地方得到了回答，但是在我最终在这里找到答案之前，谷歌首先把我带到了这里。

您可以将多个缓冲区传递给网络工作者，而无需使用Transferable 对象执行复制：

工人案例，第一个参数是数据，第二个是应该转移的项目列表。顺便说一下，第一个参数不一定是 ArrayBuffer。例如，它可以是 JSON 对象：

worker.postMessage(
  {data: int8View, moreData: anotherBuffer},
  [int8View.buffer, anotherBuffer]
);
