[Fixed] socket IO send form data from client to server


I’m trying to send a simple message from a form to my server using socket.io. Sadly enough this is failing, I know the client has a connection with the server, but it does not appear to receive the messages.

Could someone explain to me why my code is failing?


var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

app.get('/', function(req, res){
  res.sendFile(__dirname + '/index.html');

http.listen(8001, function(){
  console.log('listening on *:8001');

io.on('connection', function(socket){
  console.log('connection is er');
  socket.on('message', function(msg){
    console.log('message: ' + msg);

index.html :

    <script src="https://cdn.socket.io/socket.io-1.2.0.js"></script>
    <script src="http://code.jquery.com/jquery-1.11.1.js"></script>
      var socket = io();
        socket.emit('message', $('#Input').val());
        //socket.emit('message', "Input");
        return false;
    <form id = "form" action = "">
      Input: <input type="text" id="Input"><br>
      <input type="submit" value="Submit">


It looks like your client is using socket.io JS file from socket.io website but you didn’t specified host and port of YOUR server.

Check out the documentation http://socket.io/docs/#using-with-the-express-framework you need to do something like

var socket = io.connect('http://localhost:8001');
