大神们，求助，完全没头绪

用Node.js写过
Node.js搭建的聊天服务器,网页,手机,之间的及时通信技术.,采用socket.io
服务器端node.js 代码:
var express = require('express'), //创建一个express对象
io = require('socket.io'); //创建一个socket.io对象
var app = express();
app.use(express.static(__dirname));
var server = app.listen(1000); //监听1000端口
var ws = io.listen(server);
console.log('ok!!!!'); 输出OK
ws.on('connection', function (socket) {
socket.emit('open', '7890'); //通知客户端已经连接
console.log(‘客户端连接OK’ );
///检测IP
socket.on('send', function (msg) { //像全体用户广播
ws.emit('get', msg);
});
});

<script type="text/javascript" src="js/socket.io.js"></script>//引入socket.io
<script type="text/javascript">
$(function () {
//与服务器建立了连接
var ws = io.connect("http:双斜杠192.168.23.1:1000");
ws.on('open', function () {
alert("与服务器连接成功");
$("#btn1").click(function () {
var msg = $("#txt1").val();
ws.emit('send', msg);
});
});
ws.on('get', function (data) {
$("#txt2").val(data);
});
});
</script>
