最近在参与整合前端的框架，我们知道javascript最强大的模板引擎之一当属jsrender，号称下一代jquery模板引擎的标准实现。
通常在模板merge的过程中，我们会遇到两次乃至三级嵌套的情形，强大的jsrender自然会支持，如下所示：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<script type="text/javascript" src="jquery-1.11.1.min.js"></script>
<script type="text/javascript" src="jsrender.js"></script>
<title>jsrender nest demo</title>
</head>
<body>
<div id="studentList">abc</div>
<script type="text/x-jsrender" id="studentTemplate">
{{for #data}}
<h3>{{:name}}</h3>
<ul>
{{for language}}
<li>
{{:#parent.parent.data.name}} is learning {{:title}}<br/>
{{for scores}}
<a href="#">{{:score}}</a>
{{/for}}
</li>
{{/for}}
</ul>
{{/for}}
</script>
<script type="text/javascript">
var students = [{name:"张三",language:[{title:"中",scores:[{score:12},{score:13},{score:14}]},{title:"英",scores:[{score:12},{score:13},{score:14}]},{title:"数",scores:[{score:12},{score:13},{score:14}]}]},
{name:"李四",language:[{title:"中",scores:[{score:12},{score:13},{score:14}]},{title:"中",scores:[{score:12},{score:13},{score:14}]},{title:"中",scores:[{score:12},{score:13},{score:14}]}]},
{name:"王五",language:[{title:"中",scores:[{score:12},{score:13},{score:14}]},{title:"中",scores:[{score:12},{score:13},{score:14}]},{title:"中",scores:[{score:12},{score:13},{score:14}]}]}];
$("#studentList").html($("#studentTemplate").render(students));
</script>
</body>
</html>
效果如下：
