Socket.io numbers do not work

I have a problem because this example does not work and I do not know why ...

Server

var app = require('http').createServer(handler); var io = require('socket.io').listen(app); var fs = require('fs'); var port = 3250; app.listen(port); io.sockets.on('connection', function(socket) { socket.on('room', function(room) { socket.join(room); }); var room = abc123 io.sockets.in(room).emit('m', 'what is going on, party people?'); });

Client

 var room = "abc123"; socket.on('connect', function() { socket.emit('room', room); }); socket.on('m', function(data) { document.write(data); });

I am trying with this https://gist.github.com/crabasa/2896891 and this did not help :(

Thank you for your help!

Server:

 var app = require('http').createServer(function(req,res){}); app.listen(3250); var io = require('socket.io').listen(app) //io = socketio.listen(server); // handle incoming connections from clients io.sockets.on('connection', function(socket) { // once a client has connected, we expect to get a ping from them saying what room they want to join socket.on('room', function(room) { socket.join(room); }); socket.on('say',function(data){ io.sockets.in(data.room).emit('message',data.message); }) });

customer:

 <!DOCTYPE HTML> <html> <head> <script src="http://192.168.1.7:3250/socket.io/socket.io.js"></script> <script> // set-up a connection between the client and the server var socket = io.connect('http://192.168.1.7:3250'); // let assume that the client page, once rendered, knows what room it wants to join var room = "abc123"; socket.on('connect', function() { // Connected, let sign-up for to receive messages for this room socket.emit('room', room); }); socket.on('message', function(data) { console.log('Incoming message:', data); }); </script> </head> <body> <button onclick='socket.emit("say",{"room":room,"message":"hello world"})'>Say hello world</button> </body> </html>

change 192.168.1.7 to your IP address, good luck!
