【求助】jquery与nodejs交互

对网络技术不是很了解，是我们的课程作业。
我就是想用前台的jquery想后台发送请求，并从nodejs端返回值到前台（html）。乱试了不少代码，可是怎么样都回传不了数据。我从网上下了一串代码。可是一直说连接有错。求指点，如何能让jquery和nodejs交互成功？这个是html文件的代码，jquery.js用的是这个链接的：http://code.jquery.com/jquery-1.9.1.js。
<html>
<head>
    <script language="javascript" type="text/javascript" src="jquery.js"></script>
</head><body>
    response here: <p id="lblResponse">fill me in</p><script type="text/javascript">
$(document).ready(function() {
    $.ajax({
        url: 'http://127.0.0.1:1337/',
        // dataType: "jsonp",
        data: '{"data": "TEST"}',
        type: 'POST',
        jsonpCallback: 'callback', // this is not relevant to the POST anymore
        success: function (data) {
            var ret = jQuery.parseJSON(data);
            $('#lblResponse').html(ret.msg);
            console.log('Success: ')
        },
        error: function (xhr, status, error) {
            console.log('Error: ' + error.message);
            $('#lblResponse').html('Error connecting to the server.');
        },
    });
});
</script></body>
</html>这个是nodejs端的代码
var http = require('http');
var util = require('util')
http.createServer(function (req, res) {    console.log('Request received: ');
    util.log(util.inspect(req)) // this line helps you inspect the request so you can see whether the data is in the url (GET) or the req body (POST)
    util.log('Request recieved: \nmethod: ' + req.method + '\nurl: ' + req.url) // this line logs just the method and url    res.writeHead(200, { 'Content-Type': 'text/plain' });
    req.on('data', function (chunk) {
        console.log('GOT DATA!');
    });
    res.end('callback(\'{\"msg\": \"OK\"}\')');}).listen(1337,'127.0.0.1');
console.log('Server running on port http://127.0.0.1:1337/');看node.js command prompt 上面显示的log信息，应该是成功发送了请求，但是我不知道如何从nodejs端把数据回传到html端。html页面一直打印错误信息。求指点！还有我就是从网上下了个nodejs的windows版本，然后安装了一下，这样是不是就够了？还需要配置什么环境么？jquerynodejsajax

var http = require('http');
var util = require('util')
http.createServer(function (req, res) {

    console.log('Request received: ');
    util.log(util.inspect(req)) // this line helps you inspect the request so you can see whether the data is in the url (GET) or the req body (POST)
    util.log('Request recieved: \nmethod: ' + req.method + '\nurl: ' + req.url) // this line logs just the method and url

    res.writeHead(200, { 'Content-Type': 'text/plain' });
    var data = '';//这里加一个变量用于接收数据
    req.on('data', function (chunk) {
        data += chunk;//每次数据来了以后跟前面的连接起来
        console.log('GOT DATA!');
    });
    res.end(data);

}).listen(1337,'127.0.0.1');
console.log('Server running on port http://127.0.0.1:1337/');
好久没玩node了。印象中是像上面那样。
var http = require('http');
var util = require('util')
http.createServer(function (req, res) {

    console.log('Request received: ');
    util.log(util.inspect(req)) // this line helps you inspect the request so you can see whether the data is in the url (GET) or the req body (POST)
    util.log('Request recieved: \nmethod: ' + req.method + '\nurl: ' + req.url) // this line logs just the method and url

    res.writeHead(200, { 'Content-Type': 'text/plain' });
    var data = '';//这里加一个变量用于接收数据
    req.on('data', function (chunk) {
        data += chunk;//每次数据来了以后跟前面的连接起来
        console.log('GOT DATA!');
    });
    req.on('end', function() {
        res.end(data);//貌似得这样。而且data好像也要用querystring来处理一下
    });
}).listen(1337,'127.0.0.1');
console.log('Server running on port http://127.0.0.1:1337/');
        // dataType: "jsonp"，取消注释，另外一个帖子已经回你了~
