v-for指令：
1.用于展示列表数据
2.语法：v-for="(item,index) in arr" :key="item.id"
3.可遍历：数组、对象、字符串
-->
<!-- 准备一个容器 -->
<div id="root">
<ul>
<!-- 使用v-for遍历数组 -->
<li v-for="(item,index) in persons" :key="item.id">
{{item.id}}-----{{item.name}}------{{item.age}}岁-----{{item.sex}}
</li>
</ul>

<ul>
<!-- 使用v-for遍历对象 -->
<li v-for="(value,key) in car" :key="key">{{value}}</li>

<h2>测试遍历字符串</h2>

<li v-for="(data,index) in str">{{data}}---{{index}}</li>
