使用express+ejs构建node app 读取数据

接上篇：使用express+ejs构建node app
使用上一篇写完的程序读取数据。

修改server.js

app.get('/',function(){
    var drinks = [
                    { name : 'Bloody Mary' , drunkness : 3 },
                    { name : 'Martini' , drunkness : 5 },
                    { name : 'Scotch' , drunkness : 10 }
                ];
    var tagline = "Any code og your own that you haven't looked at for six or more months might as well have been written by someone else.";

    res.render('pages/index',{
        drinks:drinks,
        tagline:tagline
    });
});

修改index.ejs

在任何你想要显示数据的地方

<h2>Variable</h2>
<!--使用<%= Variable %>输出变量-->
<p><%= tagline %></p>
<h2>Loop</h2>
<ul>
    <% drinks.forEach(function(drink) { %>
    <li><%= drink.name %> - <%= drink.drunkness %></li>
    <% }); %>
</ul>

over。
其实还挺简单。
