javascript – 是否存在Firefox Worker限制？

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

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);
    };
}

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

刚做了一些我自己的测试.为此,我改变了一点代码：

周期：

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);
    };
}

工人：

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

在我运行之后,在chrome中我有66个cookie(包括一个漂亮的蓝色崩溃窗口),在firefox中我得到了20个.所以这两个浏览器似乎都有工作者限制.

编辑：

在Opera中我得到一个控制台消息：

此窗口超出了最大Web Worker实例数(16).
