dot.js简单入门

doT.js是一个轻量简单的模板输出js. 下面介绍一下它的基本用法。
1.输出   基本输出：{{= }}     原样输出：{{! }}

<div id="info"></div>  
<script id="dot-template" type="text/x-dot-template">  
　　<p>name:{{=it.name}}</p>  
　　<p>age:{{=it.age}}</p>  
　　<p>{{=it.html}}</p>  
　　<p>{{!it.html}}</p>  
</script>  
<script type="text/javascript">  
　　var dataJSON = {"name": "AlanJ", "age": "20", "html": "<div style='background: #f00; height: 30px; line-height: 30px;'>html元素</div>"};  
　　var html = doT.template(document.getElementById("dot-template").text)(dataJSON);  
　　document.getElementById("info").innerHTML = html;  
</script>

 2.判断 if:{{? }}   else if:{{??}}

<div id="info"></div>  
<script id="dot-template" type="text/x-dot-template">  
　　<p>name:{{=it.name}}</p>  
　　<p>score:{{=it.score}}</p>  
　　{{? it.score < 60}}  
　　<p>不及格</p>  
　　{{?? it.score < 80}}  
　　<p>及格</p>  
　　{{??}}  
　　<p>优秀</p>  
　　{{?}}  
</script>  
<script type="text/javascript">  
　　var dataJSON = {"name": "AlanJ", "score": "100"};  
　　var html = doT.template(document.getElementById("dot-template").text)(dataJSON);  
　　document.getElementById("info").innerHTML = html;  
</script>

 3.循环  for each {{~it :item:index}}  {{~}}    for in: {{for (var index in it){ }}  {{ } }}

-------------------------------------for each----------------------------------------------  
<ul id="info1"></ul>  
-------------------------------------for in----------------------------------------------  
<ul id="info2"></ul>  
<script id="dot-template1" type="text/x-dot-template">  
　　{{~it :item:index}}  
　　<li>  
　　	<p>index:{{=index + 1}}</p>  
　　	<p>name:{{=item.name}}</p>  
	<p>age:{{=item.age}}</p>  
　　</li>  
　　{{~}}  
</script>  
<script id="dot-template2" type="text/x-dot-template">  
　　{{for (var index in it){ }}  
　　<li>  
	<p>index:{{=index + 1}}</p>  
	<p>name:{{=it[index].name}}</p>  
	<p>name:{{=it[index].age}}</p>  
　　</li>  
　　{{}}}  
</script>  
<script type="text/javascript">  
　　var dataJSONArray = [{"name": "AlanJ", "age": "20"}, {"name": "Jack", "age": "40"}, {"name": "ClearLove", "age": "60"}];  
　　var html1 = doT.template(document.getElementById("dot-template1").text)(dataJSONArray);  
　　document.getElementById("info1").innerHTML = html1;  
　　var html2 = doT.template(document.getElementById("dot-template2").text)(dataJSONArray);  
　　document.getElementById("info2").innerHTML = html2;  
</script>  

 4.partials (个人理解：部分拼接 )  全：{{##def.snippet:{{#def.joke}}#}}{{#def.snippet}} 简：{{#def.joke}}

<div id="info"></div>  
<script id="dot-template" type="text/x-dot-template">  
<div>{{=it.name}}</div>  
　　{{##def.snippet:  
　　{{#def.joke}}  
　　#}}  
　　{{#def.snippet}}  
	
　　{{#def.joke}}  
</script>  
<script type="text/javascript">  
　　var dataJSON ={"name":"AlanJ"};  
　　var defPart = {"joke":"<div>{{=it.name}} who?</div>"};  
　　var html = doT.template(document.getElementById("dot-template").text, null, defPart)(dataJSON);  
　　document.getElementById("info").innerHTML = html;  
</script>

5.一个简单的例子

<table id="content">
		<script id="title">
			<tr>
				<th>姓名</th>
				<th>年龄</th>
				<th>性别</th>
			</tr>
			{{if(it.length>0){}}
				{{for (var i=0;i<it.length;i++){}}
				<tr>
					<td>{{=it[i].name}}</td>
					<td>{{=it[i].age}}</td>
					<td>{{=it[i].sex}}</td>
				</tr>
				{{}}}
			{{}else{}}
			<tr>没有数据</tr>
			{{}}}
		</script>
	</table>
	<script>
		var data=[
			{"name":"xiaoming","age":"23","sex":"male"},
			{"name":"xiaohong","age":"22","sex":"female"},
			{"name":"xiaodong","age":"21","sex":"male"},
		];
		var taxi=doT.template(document.getElementById("title").text)(data);
		document.getElementById("content").innerHTML=taxi;
	</script>
