javascript - Socket IO reconnect?

How to reconnect to socket io once disconnect has been called?

Here's the code

function initSocket(__bool){                    
    if(__bool == true){             
        socket = io.connect('http://xxx.xxx.xxx.xxx:8081', {secure:false});     
        socket.on('connect', function(){console.log('connected')});                                 
        socket.on('disconnect', function (){console.log('disconnected')});
    }else{
        socket.disconnect();
        socket = null;
    }
}   

If I do initSocket(true), it works. If I do initSocket(false), it disconnects. BUT THEN if I try to reconnect using initSocket(true), the connection does not work anymore. How can I get the connection to work?

Well, you have an option here ...

The first time you initialize the socket value you should connect with io.connect,

The next time ( after you've called disconnect once ), you should connect back with socket.socket.connect().

So your initSocket, should be something like

function initSocket(__bool){                    
    if(__bool){          
        if ( !socket ) {   
            socket = io.connect('http://xxx.xxx.xxx.xxx:8081', {secure:false});     
            socket.on('connect', function(){console.log('connected')});                                 
            socket.on('disconnect', function (){console.log('disconnected')});
        } else {
            socket.socket.connect(); // Yep, socket.socket ( 2 times )
        }
    }else{
        socket.disconnect();
        // socket = null; <<< We don't need this anymore
    }
}
