网络工作者未运行

我有以下代码：

var stressWorker = new Worker("./test/webworkers/worker.js");
stressWorker.onmessage = function(event){
    alert(event.data);
};
stressWorker.onerror = function(event){
    throw new Error(event.message + " (" + event.filename + ":" + event.lineno + ")");
};

worker.js：

onmessage = function(e){
   postMessage("test");
}

该脚本找到“worker.js”文件，但实际上并没有运行它。我做错了什么？

附言。我使用 wamp 托管这两个脚本，并且使用 chrome

I have the following code:

var stressWorker = new Worker("./test/webworkers/worker.js");
stressWorker.onmessage = function(event){
    alert(event.data);
};
stressWorker.onerror = function(event){
    throw new Error(event.message + " (" + event.filename + ":" + event.lineno + ")");
};

worker.js:

onmessage = function(e){
   postMessage("test");
}

The script finds the 'worker.js' file but it doesn't actually run it. What am I doing wrong?

PS. I'm hosting both scripts using wamp and I'm using chrome

在收到消息之前，worker.js 不会执行任何操作。我看不到你向哪里发送消息。你需要类似 stressWorker.postMessage(...) 的东西。

您确定您的浏览器支持这一特定的 HTML5 功能吗？

本文提供了多种方法来测试每个功能的支持。 Worker 的测试是

return !!window.Worker;

编辑：据我所知，您的代码有问题，或者找不到文件。您的代码看起来很像此示例，除了 .js 文件代码是这样的，带有 self：

self.onmessage = function(e) {  
    self.postMessage("Hello " + e.data);  
};

您应该很容易尝试一下，看看它是否是这里缺少的部分。

Are you sure your browser supports this particular HTML5 feature?

This article has many ways to test for support of each feature. The test for Worker is

return !!window.Worker;

Edit: As I see it, there's either a problem with your code or it can't find the file. Your code looks a lot like this example except there the .js file code is like this, with the self:

self.onmessage = function(e) {  
    self.postMessage("Hello " + e.data);  
};

It should be easy enough for you to try that and see if it's the missing piece here.

您应该记住的一件主要事情如果您在同源上运行脚本并使用 chrome，则应该使用标志 --allow-file-access-from-files 启动 chrome，或者您应该在以下位置运行应用程序本地服务器。

查看代码

 var stressWorker = new Worker("../test/webworkers/worker.js");
    stressWorker.onmessage = function(event){
        alert(event.data);
    };
    stressWorker.postMessage("Hello there");
    stressWorker.onerror = function(event){
        throw new Error(event.message + " (" + event.filename + ":" + event.lineno + ")");
    };

现在您将得到工作人员的响应。 “..”我怀疑路径错误。

One main thing You should remember If you are running scripts on same origin and using chrome, you should start the chrome with the flag --allow-file-access-from-files or You should run app on local server.

See the code

 var stressWorker = new Worker("../test/webworkers/worker.js");
    stressWorker.onmessage = function(event){
        alert(event.data);
    };
    stressWorker.postMessage("Hello there");
    stressWorker.onerror = function(event){
        throw new Error(event.message + " (" + event.filename + ":" + event.lineno + ")");
    };

Now you will get The response from the worker. ".." I suspect path is wrong.
