直接用 script 引入文件：

<script src="http://www.mamicode.com/nunjucks.js"></script>

是使用 render 来直接渲染文件，这种方式支持继承(extends)和包含(include)模板。使用之前需要配置文件的路径：

nunjucks.configure(‘views‘, { autoescape: true });
nunjucks.render(‘index.html‘, { foo: ‘bar‘ });

在 node 端，‘views‘ 为相对于当前工作目录 (working directory) 的路径。在浏览器端则为一个相对的 url，最好指定为绝对路径 (如 ‘/views‘)。

项目的目录结构如下：

其中：

主页 index.html

<!DOCTYPE html>
<html>

<head>
    <title>nunjucks 应用</title>
    <meta http-equiv="Access-Control-Allow-Origin" content="*">
</head>
<body>
<div class="contain">
    123
</div>
<script type="text/javascript" src="js/jquery-2.1.4.min.js"></script>
<script type="text/javascript" src="js/nunjucks.js"></script>
<script type="text/javascript" src="js/app.js"></script>
</body>
</html>

模板 tem_data.html ：

<div class="main">
    <table class="data-show">
        <th class="thead">
            <td class="name">名字</td>
            <td class="area_id">地区编号</td>
            <td class="area_name">地区名称</td>
            <td class="river_name">河流名称</td>
        </th>
         {% for item in data %}
        <tr>
            <td >{{item.name}}</td>
            <td >{{item.area_id}}</td>
            <td >{{item.area_name}}</td>
            <td >{{item.river_name}}</td>
        </tr>
         {% endfor %}
    </table>
</div>

app.js：

  var data=http://www.mamicode.com/[{

nunjucks.configure(‘http://127.0.0.1:8080/template‘,{autoescape:true});

var html = nunjucks.render(‘tem_data.html‘,{data:data});

//document.getElementsByClassName("contain").innerHTML=html;  //nocan

 $(".contain").append(html);//yes
//console.log(html);

 为了能够成功渲染，需要修改端口：
