使用方法： {{= }} for interpolation {{ }} for evaluation {{~ }} for array iteration {{? }} for conditionals {{! }} for interpolation with encoding {{# }} for compile-time evaluation/includes and partials {{## #}} for compile-time defines

调用方式： var tmpText = doT.template(模板); tmpText(数据源);

例子一：

1、for interpolation 赋值 格式： {{= }}

数据源：{"name":"Jake","age":31}

模板：

<script id="interpolationtmpl" type="text/x-dot-template"> <div>Hi {{=it.name}}!</div> <div>{{=it.age || ''}}</div> </script>

调用方式：

var dataInter = {"name":"Jake","age":31}; var interText = doT.template($("#interpolationtmpl").text()); $("#interpolation").html(interText(dataInter));

例子二：

2、for evaluation for in 循环 格式： {{ for var key in data { }} {{= key }} {{ } }}

数据源：{"name":"Jake","age":31,"interests":["basketball","hockey","photography"],"contact":{"email":"jake@xyz.com","phone":"999999999"}}

区域：<div id="evaluation"></div>

模板：

<script id="evaluationtmpl" type="text/x-dot-template"> {{ for(var prop in it) { }} <div>KEY:{{= prop }}---VALUE:{{= it[prop] }}</div> {{ } }} </script>

调用方式：

var dataEval = {"name":"Jake","age":31,"interests":["basketball","hockey","photography"],"contact":{"email":"jake@xyz.com","phone":"999999999"}}; var evalText = doT.template($("#evaluationtmpl").text()); $("#evaluation").html(evalText(dataEval));

例子三：

3、for array iteration 数组 格式： {{~data.array :value:index }} ... {{~}}

数据源:{"array":["banana","apple","orange"]}

区域：<div id="arrays"></div>

模板：

<script id="arraystmpl" type="text/x-dot-template"> {{~it.array:value:index}} <div>{{= index+1 }}{{= value }}!</div> {{~}} </script>

调用方式：

var dataArr = {"array":["banana","apple","orange"]}; var arrText = doT.template($("#arraystmpl").text()); $("#arrays").html(arrText(dataArr));

例子四：

4、{{? }} for conditionals 条件 格式： {{? }} if {{?? }} else if {{??}} else

数据源：{"name":"Jake","age":31}

区域：<div id="condition"></div> 模板：

<script id="conditionstmpl" type="text/x-dot-template"> {{? !it.name }} <div>Oh, I love your name, {{=it.name}}!</div> {{?? !it.age === 0}} <div>Guess nobody named you yet!</div> {{??}} You are {{=it.age}} and still dont have a name? {{?}} </script>

var dataEncode = {"uri":"http://bebedo.com/?keywords=Yoga","html":"<div style='background: #f00; height: 30px; line-height: 30px;'>html元素</div>"}; var EncodeText = doT.template($("#encodetmpl").text()); $("#encode").html(EncodeText(dataEncode));

例子五：

5、for interpolation with encoding 数据源：{"uri":"http://bebedo.com/?keywords=Yoga"}

格式： {{!it.uri}}

区域：<div id="encode"></div>

模板：

<script id="encodetmpl" type="text/x-dot-template"> Visit {{!it.uri}} {{!it.html}} </script>

调用方式：

var dataEncode = {"uri":"http://bebedo.com/?keywords=Yoga","html":"<div style='background: #f00; height: 30px; line-height: 30px;'>html元素</div>"}; var EncodeText = doT.template($("#encodetmpl").text()); $("#encode").html(EncodeText(dataEncode));

例子六：

6、{{# }} for compile-time evaluation/includes and partials {{## #}} for compile-time defines

数据源：{"name":"Jake","age":31}

区域：<div id="part"></div>

模板：

<script id="parttmpl" type="text/x-dot-template"> {{##def.snippet: <div>{{=it.name}}</div>{{#def.joke}} #}} {{#def.snippet}} {{=it.html}} </script>

调用方式：

var dataPart = {"name":"Jake","age":31,"html":"<div style='background: #f00; height: 30px; line-height: 30px;'>html元素</div>"}; var defPart = {"joke":"<div>{{=it.name}} who?</div>"}; var partText = doT.template($("#parttmpl").text(), undefined, defPart); $("#part").html(partText(dataPart));
