我是node.js的新手,并尝试在html网站上显示一个简单的表格.这个表应该填充来自mysql select的数据(例如：select * from testtable).

但我真的不明白该怎么做.对于具有PHP背景的人,如何在nodejs中的HTML中显示某些sql内容？我知道git mysql nodejs wiki但它根本没用,因为这只是关于获取数据而不是在网页上显示它.

在nodeJS中做类似事情的最佳做法是什么？有一个容易理解的方式,还是我应该继续使用PHP？我真的很喜欢关于node.js的想法,但开始就像爬一个滑溜溜的悬崖.

我也买了一本关于它的书,但这本书从来没有深入到表达(因为这将是太多的信息.??…..).所以我知道express,pug,serve-static,我能够提供一个简单的html.但就是这样,没有CRUD或REST,我付了50欧元.

编辑：
我是否需要使用API??或者是否正确使用Angular.js？

解决方法:

这里有一个例子：

app.js

var express = require('express');
var routes = require('./routes');
var http = require('http');
var path = require('path');

//Including controller/dao for testtable
var testtable = require('./routes/testtable'); 
var app = express();
var connection  = require('express-myconnection'); 
var mysql = require('mysql');
// all environments
app.set('port', process.env.PORT || 4300);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(express.static(path.join(__dirname, 'public')));
// development only
if ('development' == app.get('env')) {
  app.use(express.errorHandler());
}

app.use(
    connection(mysql,{

        host: 'localhost',
        user: 'your_user',
        password : 'your_password',
        port : 3306, //port mysql
        database:'dbname'
},'pool')
);
app.get('/testtable', testtable.list);
app.use(app.router);
http.createServer(app).listen(app.get('port'), function(){
    console.log('Express server listening on port ' + app.get('port'));
});

路线/ testtable.js

exports.list = function(req, res){

  req.getConnection(function(err,connection){   
      var query = connection.query('SELECT * FROM testtable',function(err,rows){
        if(err)
          console.log("Error Selecting : %s ",err );

        res.render('testtable',{page_title:"Test Table",data:rows});
      });
  });
};

意见/ testtable.ejs

<html><body>
<table border="1" cellpadding="7" cellspacing="7">
  <tr>
    <th width="50px">No</th>
    <th>Field 1</th>
    <th>Field 2</th>
    <th>Field 3</th>
  </tr>
  <% if(data.length){ 
    for(var i = 0;i < data.length;i++) { %>
  <tr>
    <td><%=(i+1)%></td>
    <td><%=data[i].field1%></td>
    <td><%=data[i].field2%></td>
    <td><%=data[i].field3%></td>
  </tr>
  <% }
  }else{ %>
  <tr>
    <td colspan="3">No user</td>
  </tr>
<% } %>
</table>
</body></html>

要运行此“项目”,您必须安装一些节点模块,您可以在根目录中创建一个名为“package.json”的文件：

{
  "name": "application-name",
  "version": "0.0.1",
  "private": true,
  "scripts": {
    "start": "node app.js"
  },
  "dependencies": {
    "ejs": "^1.0.0",
    "express": "3.5.1",
    "express-myconnection": "1.0.4",
    "jade": "*",
    "mysql": "2.2.0"
  }
}

并在您的项目根目录下调用“npm install”.

我希望它对你有所帮助.
