## 多线程
如何开启线程
console.log(111);
var worker = new Worker('work.js');
线程与线程传值问题
worker.postMessage('ayf');
接收
console.log(self);
self.addEventListener('message', function (e) {
console.log('You said: ' + e.data);
}, false);
拿到返回的子线程返回数据
self.onmessage = function (e) {
var uInt8Array = e.data;
postMessage('Inside worker.js: uInt8Array.toString() = ' + uInt8Array.toString());
postMessage('Inside worker.js: uInt8Array.byteLength = ' + uInt8Array.byteLength);
};
得到几个关键词
主线程 Worker onmessage postMessage
子线程 self onmessage postMessage
经过案例，我发现能通过搜索的上面的关键词快速的定位
主线程不能直接调用子线程的方法
