doT.js具体使用介绍

官网：

http://olado.github.iodoT.js具体使用介绍

用法：

{{= }} 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);





样例一：

1、for interpolation 赋值

格式：

{{= }}

数据源：{"name":"Jake","age":31}



区域:<div id="interpolation"></div>

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));







样例二：

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));







样例三：

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));









样例四：

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>

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));

样例五：

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));









样例六：

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));
