实例1:简单

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title></title>
    <script type="text/javascript" src="../../doT.js"></script>
    <script type="text/javascript" src="http://hbjltv.com/static/js/jquery-1.11.1.js"></script>
</head>
<body>
<div id="interpolationtmpl">
    <div>Hi {{=it.name}}!</div>
    <div>{{=it.age || ''}}</div>
</div>
<hr/>
<div id="interpolation"></div>
<script type="text/javascript">
    var dataInter = {"name": "Jake", "age": 31};
    var interText = doT.template($("#interpolationtmpl").html());
    $("#interpolation").html(interText(dataInter));
</script>
</body>
</html>

执行结果:

实例二:条件推断

<body>
<div id="conditionstmpl">
    {{?

!it.name }}
    <div> 你还没有名字</div>
    {{?? }}
    <div>Oh, I love your name, {{=it.name}}!</div>
    {{?

}}
</div>
<hr/>
<div id="condition"></div>
<script type="text/javascript">
    var dataEncode = {"name": "黄威", "age": 31};
    var interText = doT.template($("#conditionstmpl").html());
    $("#condition").html(interText(dataEncode));
</script>
</body>

执行结果:

if条件推断 还有另外一种写法:

<body>
<div id="conditionstmpl">
    {{ if(!it.name){ }}
    <div> 你还没有名字</div>
    {{ } else { }}
    <div>Oh, I love your name, {{=it.name}}!</div>
    {{ }  }}
</div>
<hr/>
<div id="condition"></div>
<script type="text/javascript">
    var dataEncode = {"name": "", "age": 31};
    var interText = doT.template($("#conditionstmpl").html());
    $("#condition").html(interText(dataEncode));
</script>
</body>

实例三:循环+条件推断

<body>
<div id="evaluationtmpl">
    {{ for(var prop in it) { }}
        {{? typeof it[prop]=='object' }}
            <div style="font-weight: bold;" >KEY:{{= prop }}---VALUE:</div>
            {{ for(var prop2 in it[prop]) { }}
                <div style="margin-left: 20px;" >key:{{= prop2 }}---value:{{= it[prop][prop2] }}</div>
            {{ } }}
        {{?

? }}
            <div>KEY:{{= prop }}---VALUE:{{= it[prop] }}</div>
        {{?

}}

    {{ } }}
</div>
<hr/>
<div id="evaluation"></div>
<script type="text/javascript">
    var dataEval = {
        "name": "Jake",
        "age": 31,
        "interests": ["basketball", "hockey", "photography"],
        "contact": {"email": "jake@xyz.com", "phone": "999999999"}
    };
    var evalText = doT.template($("#evaluationtmpl").html());
    $("#evaluation").html(evalText(dataEval));
</script>
</body>

执行结果:

普通循环(不是foreach)

<script id="cuslist" type="text/x-dot-template">

{{ for(var prop in it){  }}
<table>
    {{? typeof it[prop]['appName']=='object' }}
        <tr  > <td rowspan="{{=it[prop]['appName'].length}}" >{{=it[prop]['cusName']}}</td>
        <td  >{{=it[prop]['appName'][0]}}</td>
        </tr>
        {{ for(var prop2=1;prop2 <it[prop]['appName'].length; prop2++ ){ }}
            <tr><td  >{{=it[prop]['appName'][prop2]}}</td></tr>
        {{ } }}
    {{?

? }}
        <tr><td >{{=it[prop]['cusName']}}</td><td >{{=it[prop]['appName']}}</td></tr>
    {{?

}}
</table>
{{ } }}

</script>

doT 源代码及实例

说明:

1,{{? typeof it[prop]==’object’ }} 表示条件推断,结束标签是{{?}}

2, {{?? }}是条件推断的else

3,{{ 和{{? 中均能够使用原生的js语法,如for,typeof 等

4,模板并非一定要放在script标签中,也能够放在隐藏的div标签中
