<h1>Handlebars.js循环中索引(@index)使用技巧</h1>
<!--基础html框架-->
<table>
<thead>
<tr>
<th></th>
<th>姓名</th>
<th>性别</th>
<th>年龄</th>
</tr>
</thead>
<tbody id="tableList">
</tbody>
</table>
<!--插件引用-->
<script type="text/javascript" src="script/jquery.js"></script>
<script type="text/javascript" src="script/handlebars-v1.3.0.js"></script>
<!--Handlebars.js模版-->
<!--Handlebars.js模版放在script标签中，保留了html原有层次结构,模版中要写一些操作语句-->
<!--id可以用来唯一确定一个模版,type是模版固定的写法-->
<script id="table-template" type="text/x-handlebars-template">
{{#each this}}
<tr>
<td>{{addOne @index}}</td>
<td>{{name}}</td>
<td>{{sex}}</td>
<td>{{age}}</td>
</tr>
{{#each family}}
<tr>
<td>{{../_index}}.{{@index}}</td>
<td>{{name}}</td>
<td>{{sex}}</td>
<td>{{age}}</td>
</tr>
{{/each}}
{{/each}}
</script>
<!--进行数据处理、html构造-->
<script type="text/javascript">
var data = [{
name: "张三",
sex: "男",
age: 35,
family: [{
name: "张三儿子",
sex: "男",
age: 10,
},{
name: "张三妻子",
sex: "女",
age: 33,
}]
},{
name: "李四",
sex: "男",
age: 23,
family: [{
name: "李四妻子",
sex: "女",
age: 23,
}]
},{
name: "甜妞",
sex: "女",
age: 18,
family: [{
name: "甜妞妈妈",
sex: "女",
age: 40,
},{
name: "甜妞爸爸",
sex: "男",
age: 43,
},{
name: "甜妞姥爷",
sex: "男",
age: 73,
}]
}];
//注册索引+1的helper
var handleHelper = Handlebars.registerHelper("addOne",function(index){
//利用+1的时机，在父级循环对象中添加一个_index属性，用来保存父级每次循环的索引
this._index = index+1;
//返回+1之后的结果
return this._index;
});
//解析模版
var handle = Handlebars.compile($("#table-template").html());
//生成html
var html = handle(data);
//插入到页面
$("#tableList").append(html);
</script>
</body>
</html>
