它可以在Google Chrome中完美运行。当我试图在Firefox中运行它时，它只能运行20次。 Firefox网络工作者是否有限制？我在mozilla.org上找不到关于它的信息。如果没有限制，那有什么问题？任何想法？

解决方案

刚做了一些我自己的测试。为此，我改变了一下代码：

循环：

  for（var i = 0; i <200; i ++）{
 this.createWorker（）; 
 this.workers [this.workersPointer] .postMessage（{task：'someTask'，number：i}）; 
}; 
  

createWorker函数：

  this.workers = []; 
 this.workersPointer = 0; 
 storage = []; 
 
 
 var createWorker = function（）{
 workersPointer ++; 
 var myPointer = workersPointer; 
 var worker = this.workers [this.workersPointer] = new Worker（'Worker.js'）; 
 
 worker.onmessage = function（event）{
 if（event.data.error）{
 alert（event.data.error）; 
} 
 else {
 document.cookie = event.data.task +[+ myPointer +] =+ event.data.number; 
} 
}; 
 worker.onerror = function（event）{
 alert（Error：+ event.error）; 
}; 
 
 $ / code> 

工人：



 onmessage = function（event）{
 postMessage（{number：event.data.number * 2，task：event.data.task}）; 
}; 
  

在我运行这个之后，在chrome中我得到了66个cookie（包括一个漂亮的蓝色崩溃窗口） firefox我得到了20.所以这两个浏览器似乎有工人的限制。

$ b $在Opera中我得到一个控制台消息：

此窗口超出Web Worker实例（16）的最大数量。

Im trying to create web Workers and post messages to them in cycle:

array.forEach(function (data) {
        this.createWorker();
        this.workers[this.workersPointer].postMessage({task: 'someTask', data: string});
    }, this);

createWorker function:

createWorker: function () {
    this.workersPointer++;
    var worker = this.workers[this.workersPointer] = new Worker('Worker.js'),
        storage = this;
    worker.onmessage = function (event) {
        if (event.data.error) {
            storage[event.data.task + 'Errback'](event.data.error);
        }
        else {
            storage[event.data.task + 'Callback'](event.data.data);
        }
    };
    worker.onerror = function (error) {
        storage.workerErrback(error);
    };
}

Worker code:

self.addEventListener('message', function (event) {
self.postMessage({
    data: data,
    error: err,
    task: event.data.task
});

}, false);

It works perfectly in Google Chrome. When I'm trying to run it in Firefox, it works only 20 times. Do Firefox web workers have a limit? I can't find information about it on mozilla.org. If there is no limit, what's the problem? Any ideas?

解决方案

Just did some test of my own. For this, i changed the code a little bit:

Cycle:

for(var i=0;i<200;i++){
   this.createWorker();
   this.workers[this.workersPointer].postMessage({task: 'someTask', number:i});
};

createWorker function:

this.workers =[];
this.workersPointer = 0;
storage=[];


var createWorker= function () {
    workersPointer++;
    var myPointer = workersPointer;
    var worker = this.workers[this.workersPointer] = new Worker('Worker.js');

    worker.onmessage = function (event) {
        if (event.data.error) {
            alert(event.data.error);
        }
        else {
            document.cookie=event.data.task+"["+myPointer+"]="+event.data.number;
        }
    };
    worker.onerror = function (event) {
        alert("Error: " + event.error);
    };
}

Worker:

onmessage = function(event) {
    postMessage({number:event.data.number*2, task: event.data.task});
};

After i run this, in chrome i got 66 cookies (including a nice blue crash window), in firefox i got 20. So both browsers seem to have worker limitations.

EDIT:

In Opera i get a console message:

Maximum number of Web Worker instances(16) exceeded for this window.
