浅谈js解决多线程 webWorker介绍（图文教程）

index.js
    worker =  new Worker("/static/js/worker.js");    //最好先判断浏览器是否支持worker,我的项目用的是谷歌，所以就不判断了！
    //最好不要反复创建worker 因为worker是开辟了一个新空间
    worker.postMessage({
        type:"all",
        id:id
    });    //发送消息到worker.js中
    worker.addEventListener("message",function(e){
        console.log("接收消息",e.data.content);
})//监听worker发回来的消息！1234567891011121314
worker.js
onmessage = function (event){//监听消息
    console.log("worker.event.data:",event.data);    var postStr ="par_ser="+event.data.id;    var url ="";    if(event.data.type == "all"){
        url = "/api/getwxinfo/getCustomer";
    }else if(event.data.type == "char"){
        url = "/api/getwxinfo/getchating";
        postStr = postStr+"&num="+event.data.num;
    }    var xmlhttp=new XMLHttpRequest();    var content = "";
         xmlhttp.open('POST',url,true);
         xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
         xmlhttp.send(postStr);
         xmlhttp.onreadystatechange = function(){            if(xmlhttp.readyState==4 && xmlhttp.status==200){
                content = xmlhttp.responseText;                self.postMessage({                type:event.data.type,
                content : content
                });
            }
         }
}

Gears.jsvar worker = google.gears.factory.create('beta.workerpool');//创建worker Pool，之后创建workerworker.onmessage = function(e){
    console.log(e.body);
}//创建workervar workerid = worker.createWorkerFromUrl("js/GearsWorker.js");//发送信息到worker中worker.sendMessage(getValueToDecrypt(),workerid);123456789
GearsWorker.jsvar workerpool = google.gears.workerPool;
workerpool.onmessage = function(e){
 //把值回传主进程    workerpool.sendMessage(decryptedValue,e,sender);}
