HTML中的jQuery，node.js作为后端 [英] jQuery in HTML with node.js as backend
问题描述
我是jQuery和node.js的新手，这个问题已经困扰了我几个小时，我搜索了stackoverflow和google搜索，但找不到解决方案。
我在jQuery中测试了这个hello world的例子，我试着用node.js来运行它，但它没有用。
这里是我的node.js服务器代码：
var express = require（'express'）;
var fs = require（fs）;
var app = express.createServer（express.logger（））;
var path = require（'path'）;
var indexText = fs.readFileSync（test.html）;
app.use（'/ jquery'，express.static（__ dirname +'/ jquery'））;
$ b app.get（'/'，function（request，response）{
response.send（indexText.toString（））;
}）;
var port = process.env.PORT || 8080;
app.listen（port，function（）{
console.log（Listening on+ port）;
}）;
如你所见，我尝试使用express.static（）来告诉node.js在哪里jQuery lib位于。
这里是test.html的html：
< html>
< head>
< title> jQuery Hello World< / title>
< script type =text / javascriptsrc =/ jquery / jquery-1.2.6.min.js>< / script>
< / head>
< body>
< script type =text / javascript>
$ b $（文档）.ready（函数（）{
$（＃msgid）。html（This is Hello World by JQuery）;
}）;
< / script>
这是HTML世界的Hello World
< div id =msgid>
< / div>
< / body>
< / html>
它应该打印：
这是Hello World by HTML
这是JQuery的Hello World
但它仅打印HTML中的hello
这个问题可能是愚蠢的，但我是新手，所以我需要你的帮助。谢谢。
好的，我找到了一个解决方案。
这是一个代码帮助我的git仓库：

I'm new to jQuery and node.js and this question has been bugging me for a couple of hours, I've searched stackoverflow and googled but couldn't find a solution.
I'm testing this "hello world" example in jQuery and I tried running it with node.js, but it didn't work.
Here is my code for node.js server:
var express = require('express');
var fs = require("fs");
var app = express.createServer(express.logger());
var path = require('path');
var indexText = fs.readFileSync("test.html");
app.use('/jquery', express.static(__dirname + '/jquery'));
app.get('/', function(request, response) {
response.send(indexText.toString());
});
var port = process.env.PORT || 8080;
app.listen(port, function() {
console.log("Listening on " + port);
});
So as you can see, I tried use express.static() to tell the node.js where jQuery lib is located. Here is the html for test.html:
<html>
<head>
<title>jQuery Hello World</title>
<script type="text/javascript" src="/jquery/jquery-1.2.6.min.js"></script>
</head>
<body>
<script type="text/javascript">
$(document).ready(function(){
$("#msgid").html("This is Hello World by JQuery");
});
</script>
This is Hello World by HTML
<div id="msgid">
</div>
</body>
</html>
It should print:
This is Hello World by HTML This is Hello World by JQuery
but it only prints hello from HTML
The question might be stupid but I'm new to this so I require your help. Thank you.
Ok, I found a solution to what I was asking. Here is a git repository with code that helped me:

and here is the tutorial with the code (it is on Spanish, but let the Google Chrome translate the entire page for you, it is ok)
