dot doT.js的使用

doT.js的使用

 

引言

doT.js可以更好的在html端使用json数据。

{{ }}     for evaluation 模板标记符
{{= }}    for interpolation 输出显示，默认变量名叫it
{{! }} for interpolation with encoding 编码后输出显示 {{? }} for conditionals 条件分支，if条件的简写 {{~ }} for array iteration 遍历数组

使用

引入js

    <script type="text/javascript" src="../script/doT.min.js"></script> <!-- jquery 移动端替代品 --> <script type="text/javascript" src="../script/zepto.min.js"></script> <!--<script type="text/javascript" src="../script/jquery.min.js"></script>-->

功能点

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 dataCondition = {"age":31};
var conText = doT.template($("#conditionstmpl").text()); $("#condition").html(conText(dataCondition));
