doT.js详细解析

doT.js特点是快，小，无依赖其他插件。

官网：http://olado.github.io

使用方法：

1){{= }} for interpolation

2){{ }}   for evaluation

3){{~ }}  for array iteration

4){{? }}  for conditionals

5){{! }}  for interpolation with encoding

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

7){{## #}}    for compile-time defines

调用方式：

var tmpText = doT.template(模板);

tmpText(数据源);

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));

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":"[email protected]","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":"[email protected]","phone":"999999999"}};

var evalText = doT.template($("#evaluationtmpl").text());

$("#evaluation").html(evalText(dataEval));

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));

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));

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));

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));
