#### 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);
```
### 示例1：for interpolation 赋值
格式：
`{{= }}`
例子：
```
<div id="interpolation"></div>
<script id="interpolationtmpl" type="text/x-dot-template">
<div>Hi {{=it.name}}!</div> <div>{{=it.age || ''}}</div>
</script>
<script>
var dataInter = {"name":"Jake","age":31};
var interText = doT.template($("#interpolationtmpl").text());
$("#interpolation").html(interText(dataInter));
</script>
```
*****
### 示例2：for evaluation for in 循环
格式：
```
{{ for var key in data { }}
{{= key }}
{{ } }}
```
例子：
```
<div id="interpolation"></div>
<script id="interpolationtmpl" type="text/x-dot-template">
{{ for(var prop in it) { }}
<div>KEY:{{= prop }}---VALUE:{{= it[prop] }}</div>
{{ } }}
</script>
<script>
var dataInter ={"name":"Jake","age":31,"interests":["basketball","hockey","photography"],"contact":{"email":"jake@xyz.com","phone":"999999999"}};
var interText = doT.template($("#interpolationtmpl").text());
$("#interpolation").html(interText(dataInter));
</script>
```
### 示例3：{{~ }} for array iteration 数组
格式：
```
{{~data.array :value:index }}
...
{{~}}
```
例子：
```
<div id="interpolation"></div>
<script id="interpolationtmpl" type="text/x-dot-template">
{{~it.array:value:index}}
<div>{{= index+1 }}{{= value }}!</div>
{{~}}
</script>
<script>
var dataInter ={"array":["banana","apple","orange"]};
var interText = doT.template($("#interpolationtmpl").text());
$("#interpolation").html(interText(dataInter));
</script>
```
### 示例4：{{? }} for conditionals 条件
格式：
```
{{? }} if
{{?? }} else if
{{??}} else
```
例子：
```
<div id="interpolation"></div>
<script id="interpolationtmpl" type="text/x-dot-template">
{{? !it.name }}
<div>Oh, I love your name, {{=it.name}}!</div>
{{?? !it.age === 0}}
<div>Guess nobody named you yet!</div>
{{??}}
You are {{=it.age}} and still dont have a name?
{{?}}
</script>
<script>
var dataInter ={"name":"Jake","age":31};
var interText = doT.template($("#interpolationtmpl").text());
$("#interpolation").html(interText(dataInter));
</script>
```
### 示例5：for interpolation with encoding
格式：
```
{{!it.uri}}
```
例子：
```
<div id="interpolation"></div>
<script id="interpolationtmpl" type="text/x-dot-template">
Visit {{!it.uri}} {{!it.html}}
</script>
<script>
var dataInter ={"uri":"http://jq22.com/?keywords=Yoga","html":"<div style='background: #f00; height: 30px; line-height: 30px;'>html元素</div>"};
var interText = doT.template($("#interpolationtmpl").text());
$("#interpolation").html(interText(dataInter));
</script>
```
### 示例6：{{# }} for compile-time evaluation/includes and partials {{## #}} for compile-time defines
例子：
```
<div id="part"></div>
<script id="parttmpl" type="text/x-dot-template">
{{##def.snippet:
<div>{{=it.name}}</div>{{#def.joke}}
#}}
{{#def.snippet}}
{{=it.html}}
</script>
<script>
var dataPart = {"name":"Jake","age":31,"html":"<div style='background: #f00; height: 30px; line-height: 30px;'>html元素</div>"};
var defPart = {"joke":"<div>{{=it.name}} who?</div>"};
var partText = doT.template($("#parttmpl").text(), undefined, defPart);
$("#part").html(partText(dataPart));
</script>
```
