1、解压目录到d盘 mongodb
2、安装目录的下新建文件mongo.config文件
##store data here
dbpath=D:\mongodb\data
##all output go here
logpath=D:\mongodb\log\mongo.log
##log read and write operations
diaglog=3
3、d:\mongodb\bin>mongod --config D:\mongodb\mongo.config
4、d:\mongodb\bin> mongod --config D:\mongodb\mongo.config --install net start MongoDB
net stop MongoDB
mongod --remove
express -e demo
2、初始化相关组件
3、运行app.js，访问：http://localhost:3000，查看页面，如看到以下页面则说明页面访问成功：
var ejs = require('ejs'); //增加
app.engine('html',ejs.__express); //增加
//将app.set('view engine', 'ejs'); 修改为app.set('view engine', 'html');
b) 重命名views下的index.ejs为index.html
app.get('/add.html',routes.add); //跳转到添加页面
app.post('/add.html', routes.create);//添加记录
app.get('/del.html',routes.delById);//删除
app.get('/modify.html', routes.toModify); //跳转到修改页面
app.post('/modify.html', routes.modify);//修改数据
2）在routes目录下创建model.js文件，内容如下：
var mongoose = require('mongoose');
var Schema = mongoose.Schema;
var demoSchema = new Schema({
uid : String,
title:String,
content:String,
createTime : { type: Date, default: Date.now }
});
exports.Demo = mongoose.model('Demo',demoSchema); //此处Demo会自动对应数据库中的demos表，不知道是不是可以修改，反正我是这个认为的。
3）修改index.js，添加逻辑方法
/*
* GET home page.
*/
var mongoose = require('mongoose');
var model = require('./model');
var Demo = model.Demo;
mongoose.connect('mongodb://localhost/monkey');
exports.index = function(req, res){
//查询所有数据，保存到demos中，在页面循环输出
Demo.find(function(err,docs){
res.render('index', {
title:'Express Demo Example',
demos:docs
});
});
};
//跳转到添加页面
exports.add = function(req, res) {
console.log('----here');
res.render('add.html', {title :'添加 demo list'});
};
//创建新纪录
exports.create = function(req, res){
var demo = new Demo({
uid : req.body.uid,
title: req.body.title,
content : req.body.content
});
console.log('create----');
demo.save(function(err,doc){
console.log(doc);
res.redirect('/');
});
};
// 根据id删除相应的记录
exports.delById = function(req, res) {
var id = req.query.id;
console.log('id = ' + id);
if(id && '' != id) {
console.log('----delete id = ' + id);
Demo.findByIdAndRemove(id, function(err, docs) {
console.log('delete-----'+ docs);
res.redirect('/');
});
}
};
// 查询对应修改记录，并跳转到修改页面
exports.toModify = function(req, res) {
var id = req.query.id;
console.log('id = ' + id);
if(id && '' != id) {
console.log('----delete id = ' + id);
Demo.findById(id, function(err, docs){
console.log('-------findById()------' + docs);
res.render('modify.html',{title:'修改ToDos',demo:docs});
});
};
};
//修改相应的值
exports.modify = function(req, res) {
var demo = {
uid : req.body.uid,
title: req.body.title,
content : req.body.content
};
var id = req.body.id; //因为是post提交，所以不用query获取id
if(id && '' != id) {
console.log('----update id = ' + id + "," + demo);
Demo.findByIdAndUpdate(id, demo,function(err, docs) {
console.log('update-----'+ docs);
res.redirect('/');
});
}
};
4）index.html页面
<!DOCTYPE html>
<html>
<head>
<title><%= title %></title>
<link rel='stylesheet' href='/stylesheets/style.css' />
<style type="text/css">
table { border:1px solid green;}
table thead tr th{ border:1px solid green;}
table tbody tr td{ border:1px solid green;}
</style>
</head>
<body>
<p>
<a href="http://houzhiqingjava.blog.163.com/blog/add.html">增加</a>
</p>
<h1>DEMO List</h1>
<table>
<thead>
<tr>
<th>id</th>
<th>uid</th>
<th>title</th>
<th>content</th>
<th>createTime</th>
<th>操作</th>
</tr>
</thead>
<tbody>
<% demos.forEach(function( demo ){ %>
<tr>
<td><%=demo._id%></td>
<td><%= demo.uid %></td>
<td><%= demo.title %></td>
<td><%= demo.content %></td>
<td><%=demo.createTime%></td>
<td><a href="http://houzhiqingjava.blog.163.com/blog/del.html?id=<%=demo._id%>">Delete</a> | <a href="http://houzhiqingjava.blog.163.com/blog/modify.html?id=<%=demo._id%>">Update</a></td>
</tr>
<% }); %>
</tbody>
</table>
</body>
</html>
5）add.html页面
<!DOCTYPE html>
<html>
<head>
<title><%= title %></title>
<link rel='stylesheet' href='/stylesheets/style.css' />
<style type="text/css">

</head>
<body>
<h1>

<input type="reset" value="reset"/>
</form>

</html>
6） 修改页面modify.html
<!DOCTYPE html>
<html>
<head>
<title><%= title %></title>
<link rel='stylesheet' href='/stylesheets/style.css' />

<body>
<h1>
