doT.js学习

doT.js特点是快,小,无依赖其他插件。但是一般和jquery一起使用

官网:
http://olado.github.io

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);

案例一:

1、引入js

<script type="text/javascript" src="js/doT.min.js" ></script>
   <script type="text/javascript" src="js/jquery-1.11.3.min.js" ></script>

2、创建模板

<script id="temp" type="template">

    {{for(var i=0;i<it.length;i++ ){}}
    <li>{{=it[i]}}</li>
    {{}}}
</script>

   3、使用模板替代原内容

<script type="text/javascript">
   $(function(){
   var data=['z','x','l','nice'];
   var interText = doT.template($("#temp").text());
  $("#ulList").html(interText(data));
  })
</script>

4、html

<ul id="ulList">
   <li>1</li>
   <li>2</li>
   <li>3</li>
</ul>

5、也可以使用按钮调用js方法替代原内容

6、完整代码

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>first doT</title>
<script type="text/javascript" src="js/doT.min.js" ></script>
<script type="text/javascript" src="js/jquery-1.11.3.min.js" ></script>
<script id="temp" type="template">
{{for(var i=0;i<it.length;i++ ){}}
<li>{{=it[i]}}</li>
{{}}}
</script> </head>
<body>
<ul id="ulList">
<li>1</li>
<li>2</li>
<li>3</li>
</ul>
<script type="text/javascript">
$(function(){
var data=['z','x','l','nice'];
var interText = doT.template($("#temp").text());
$("#ulList").html(interText(data));
}) </script>
</body>
</html>

案例二:

2、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));

例子三:

3、{{? }} 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));

个人大概总结了怎么几个c,没有涉及到的自学吧
