'connect' event is not triggered on Firefox and Chrome

[learningKool]

hi all!

I'm a newbie for socket.io. I have downloaded an example for understanding how socket.io works. And i meet an issue that I can't explain why!

Here is my client code:

<script src="socket.io.js"></script>
<script>

    // Create SocketIO instance
    var socket;

    // Sends a message to the server via sockets
    function sendMessageToServer(message) {
        if(socket){
                socket.send(message);
            log('<span style="color:#888">Sending "' + message + '" to the server!</span>');
        }//socket.flushBuffer;
    }

    function disconnect(){

    }

    function reconnect(){
        socket = io.connect(
            'http://localhost:8080'
        );
        //socket.connect();

        // Add a connect listener
        socket.on('connect',function() {
            log('<span style="color:green;">Client has connected to the server!</span>');
            //server.send('hello world');
        });
        // Add a connect listener
        socket.on('message',function(data) {
            log('Received a message from the server:  ' + data);
        });
        // Add a disconnect listener
        socket.on('disconnect',function() {
            log('<span style="color:red;">The client has disconnected!</span>');
        });
    }

    // Outputs to console and list
    function log(message) {
        var li = document.createElement('li');
        li.innerHTML = message;
        document.getElementById('message-list').appendChild(li);
    }
</script>

and server code:

// Require and Socket.IO
var io = require('./lib/socket.io');

// Create a Socket.IO instance, passing it our server
var socket = io.listen(8080);
console.log('Server is started!');
// Add a connect listener
socket.on('connection', function(client){ 

// Create periodical which ends a message to the client every 5 seconds
var interval = setInterval(function() {
    client.send('This is a message from the server!  ' + new Date().getTime());
},5000);

// 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');
});

});

My PC runs win7 32bit.

I run my client on Firefox and Chrome with follow steps:

1. Run my server by command: node server.js
2. Open my client on browser.
3. Click 'Connect' button to call reconnect() function.
4. Notice that 'connect' event is not triggered. By now, server can send a message 'This is a message from the server!' to client and client can receive this.
5. I shutdown server and realize 'connect' event is triggered on client side.

When i run my client on IE9. Everything is ok. 'Connect' event is normally triggered before client can receive message from server.

And a weird thing is when i copy my source to my friend PC which runs win7 32bit, everything is ok on every browser like when i run my client on IE9.

So, where is wrong here? Do i make a mistake? Do i config something wrong?

Pls help me! Thanks.

hi there!

I've found it. Because of my IDM, I remove it and everything is ok!

Thank you for your support.
