Heya I'm trying to build a small chat client to learn how websockets work in order to make a game in canvas. It works great with sending sockets but they are only sending it to the the one who wrote it.
I guess I've missed something small, but I can't understand why it won't work.
Server side code
var app = require('express')()
, server = require('http').createServer(app)
, io = require('socket.io').listen(server);
server.listen(3000);
app.get('/', function (req, res) {
res.sendfile(__dirname + '/index.html');
});
io.sockets.on('connection', function (socket) {
socket.on('user-message', function (data) {
console.log(data);
sendMessage(data.message);
});
});
var sendMessage = function(message) {
io.sockets.emit('server-message', {message: message});
}
Client side code
<script src="/socket.io/socket.io.js"></script>
<script>
var socket = io.connect('http://localhost');
socket.on('server-message', function (data) {
var history = $('#chatbox').val();
$('#chatbox').val(history + "\n" + data.message)
});
$("#write").keyup(function(event){
if(event.keyCode == 13){
socket.emit('user-message', {message: $(this).val()});
$(this).val('');
}
});
</script>
You can use socket.broadcast.emit
to send a message to all other sockets.
io.sockets.on('connection', function (socket) {
socket.on('user-message', function (data) {
console.log(data);
sendMessage.call(socket, data.message);
});
});
var sendMessage = function(message) {
this.emit('server-message', {message: message});
this.broadcast.emit('server-message', {message: message});
}
