v-for最简单的遍历数组

<div id="app">
<ul>
<!-- v-for最基础的数组遍历 -->
<li v-for = 'i in names'>{{i}}</li>
</ul>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
const app = new Vue({
el: '#app',
data : {
names : ['jack','mary','lucy','jerry']
}
})
</script>
</body>
</html>
如果需要索引（下标），添加index即可
<li v-for = '(i, index) in names'>{{index}}+{{i}}</li>
v-for遍历对象

<body>
<div id="app">
<ul>
<li v-for = '(value,key) in info'>{{key}}----{{value}}</li>
</ul>
</div>
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script>
const app = new Vue({
el: '#app',
data : {
info : {
name :'mary',
age : 20,
gender : 'female'
}
}
})
</script>
</body>
</html>
也可以用index获取下标，在对象的遍历中比较少用
