Node.js 使用 Socket.io 将客户端连接到服务器

我对node比较陌生.js和它的插件，所以这可能是一个初学者的问题.

我试图在Web服务器上获得一个简单的HTML页面，并将其连接到另一个运行 node 的服务器.js和websocket.伊奥.

我的代码如下所示:

Client

<script src="socket.io/socket.io.js"></script>
<script>
    // Create SocketIO instance, connect

    var socket = new io.Socket();

    socket.connect('http://127.0.0.1:8080'); 

    // Add a connect listener
    socket.on('connect',function() {
      console.log('Client has connected to the server!');
    });
    // Add a connect listener
    socket.on('message',function(data) {
      console.log('Received a message from the server!',data);
    });
    // Add a disconnect listener
    socket.on('disconnect',function() {
      console.log('The client has disconnected!');
    });

    // Sends a message to the server via sockets
    function sendMessageToServer(message) {
      socket.send(message);
    };
</script>

Serverside

// Require HTTP module (to start server) and Socket.IO
var http = require('http');
var io = require('socket.io');
var port = 8080;

// Start the server at port 8080
var server = http.createServer(function(req, res){ 
    // Send HTML headers and message
    res.writeHead(200,{ 'Content-Type': 'text/html' }); 
    res.end('<h1>Hello Socket Lover!</h1>');
});

server.listen(port);

// Create a Socket.IO instance, passing it our server
var socket = io.listen(server);

// Add a connect listener
socket.on('connection', function(client){ 
    console.log('Connection to client established');

    // Success!  Now listen to messages to be received
    client.on('message',function(event){ 
        console.log('Received message from client!',event);
    });

    client.on('disconnect',function(){
        clearInterval(interval);
        console.log('Server has disconnected');
    });
});

console.log('Server running at http://127.0.0.1:' + port + '/');

启动服务器可以正常工作，在我的浏览器中运行http://localhost:8080也可以正常工作，并按预期返回"Hello Socket Lover".但我想让另一个页面与套接字对话，而不是从 node 运行一个.js.

但当我运行它时，什么都没有发生，Chrome控制台返回:

Failed to load resource            http://undefined/socket.io/1/?t=1333119551736
Failed to load resource            http://undefined/socket.io/1/?t=1333119551735

我已经干了一整天了.有什么帮助吗？
