本文介绍了PureJS模板引擎的特点及使用方法，展示了如何利用该引擎将JSON数据渲染到HTML模板中，实现动态内容填充，同时支持多次渲染同一模板。

现在有许多javascript模板引擎和服务器端的freemarker那些很像，定义模板像下面：

<textarea id="template" style="display:none">  
  <strong>{$T.name} : {$T.list_id}</strong>  
  <table>  
    <tr>  
      <th>编号</th>  
      <th>姓名</th>  
      <th>年龄</th>  
      <th>邮箱</th>  
    </tr>  
    {#foreach $T.table as record}  
    <tr>  
      <td>{$T.record.id}</td>  
      <td>{$T.record.name}</td>  
      <td>{$T.record.age}</td>  
      <td>{$T.record.mail}</td>  
    </tr>  
    {#/for}  
   </table>  
</textarea>

感觉对html改动较大，pure就不一样了，对美工做的html影响很小。看下面一个例子：

<html>
<head>
	<title>PURE Unobtrusive Rendering Engine</title>
	<script src="../libs/jquery.js"></script>
	<script src="../libs/pure.js"></script>
  <style>
    .even td { background : #DDD }
    .odd  td { background : #FFF }
  </style>
</head>
<body>
	<div style="width:100%; height: 288px; overflow: auto;">
		<!-- HTML 模板 -->
		<table id="mytb1" class="rc_bk" width="100%" border="0" cellspacing="0" cellpadding="0">
			  <tr onmouseover="$(this).addClass('highlight');" onmouseout="$(this).removeClass('highlight');">
				<td width="25%" class="rownum rightborder"></td>
				<td width="25%" class="company rightborder"></td>
				<td width="25%" class="amount rightborder"></td>
				<td width="25%" class="increment"></td>
			  </tr>
		</table>
	</div>	
	<script>
		// the JSON data we want to render
		var data = {"rows":[{"company":'adobe',"increment":1552,"amount":14810},{"company":'google',"increment":-541,"amount":7470},{"company":'bea',"increment":865,"amount":6700},{"company":'red',"increment":756,"amount":6643},{"company":'abc',"increment":180,"amount":6239},{"company":'jboss',"increment":609,"amount":6219},{"company":'中华',"increment":-1116,"amount":6036},{"company":'no',"increment":95,"amount":5593},{"company":'sun',"increment":-143,"amount":4660},{"company":'test',"increment":-357,"amount":4541},{"company":'oracle',"increment":-181,"amount":4327},{"company":'dark',"increment":-393,"amount":3252},{"company":'ibm',"increment":-567,"amount":3147}]};
	    var directive = {
	    	    'tr' : { //trigger a loop
	    	      'row<-rows' : { // loop on the property animals in the JSON 
			    	'td.rownum': function(arg){if(arg.pos == arg.row.items.length - 1) return ''; return arg.pos + 1;},
					'td.company': '#{row.company}',
					'td.amount': '#{row.amount}',
					'td.increment': '#{row.increment}',
	    	        '@class+':function(arg){ // add(+) the return value of the function to the class
	    	          return (arg.pos % 2 == 0) ? ' even' : ' odd';
	    	        }
	    		   }
	    	     }
	    	    };

		// run the rendering
		$('#mytb1').render( data, directive );
	</script>
</body>
</html>
