I want to write a simple chat for practical experience.

All right, but I can't get a socket.nickname for notice a join/leave from the room. (when I tried pass its, he always sad a 'undefined').

Now all right, tried to create list of rooms

UPDATE CODE:

client.js:

$('#roomForm').submit(function() {

    socket.emit('createRoom', $('#roomName').val());

    $('#roomForm').hide();

    $('#chatForm').show();

    return false;

});



socket.on('message', function(data) {

    newMessage(data);

});



socket.on('showRooms', function(rooms) {

    console.log(rooms);

    for(var i = 0; i < rooms.length; i++) {

        $('#rooms').append($('<li>')

                        .append($('<form id=freeRoom>')

                            .append($('<span id=room>').text(rooms[i] + ' ///'))

                            .append($('<button>').text('connect'))));

    };

});



$('#freeRoom').submit(function() {

    socket.emit('connectToRoom', $('#room').text());

    return false;

});

server.js:

io.on('connection', function(socket) {

    socket.on('sendNickname', function(username) {

        socket.username = username;

        users.push(socket.username);

        socket.emit('showRooms', rooms);

    });



    socket.on('disconnect', function() {

        socket.broadcast.to(socket.room).emit('notice', socket.username + ' has left the room');

        users.splice(users.indexOf(socket.username), 1);

        socket.emit('showRooms', rooms);

    });



    socket.on('message', function(data) {

        socket.broadcast.to(socket.room).emit('message', data);

    });



    socket.on('createRoom', function(room) {

        socket.leave(socket.room);

        socket.room = room;

        rooms.push(socket.room);

        socket.join(socket.room);

        socket.emit('showRooms', rooms);

        console.log('Rooms: ' + rooms);

        socket.broadcast.to(socket.room).emit('notice', socket.username + ' has joined to room');

    });



    socket.on('connectToRoom', function(room) {

        console.log('Will connect to that room: ' + room);

        socket.join(room);

    });

});

**UPD 2: **
Tried to connect free created room:

$('#freeRoom').submit(function() {

    socket.emit('connectToRoom', $('#room').text());

    return false;

});

P.S. And... Sorry for my english >.<
