前面的文章中介绍的vue.js的v-if和v-show的简单用法，这篇文章中简单介绍下vue中循环语法。
1.基础用法
参考代码：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<script src="https://cdn.jsdelivr.net/npm/vue"></script>
</head>
<body>
<!-- 制作一个容器 -->
<div id="first">
<div v-for="item in res">
{{item.name}}
</div>
</div>
<script type="text/javascript">
var app= new Vue({
el:'#first',
data:{
res:[
{name:"语文"},
{name:"数学"},
{name:"英语"},
{name:"体育"},
]
}
})
</script>
</body>
</html>

{name:"体育"},
]
}
})
</script>
</body>
</html>

<div v-for="item in res">
{{item.name}}
</div>
</div>
<script type="text/javascript">
var app= new Vue({

data:{
res:[
{name:"语文"},
{name:"数学"},
{name:"英语"},
{name:"体育"},
]
}
})
</script>
</body>
</html>
注意，数组这个地方用冒号，不是等号。
效果：
语文
数学
英语
体育2.复杂一点的用法
<div id="first">
<div v-for="item in res">
<li>{{item.id}}</li>
<li>{{item.name}}</li>
<li>{{item.score}}</li>
</div>
</div>
<script type="text/javascript">
var app= new Vue({
el:'#first',
data:{
res:[
{id:"1",name:"语文",score:43},
{id:"2",name:"数学",score:64},
{id:"3",name:"英语",score:45},
{id:"4",name:"体育",score:76},
]
}
})
</script>效果图：
这个可以用于渲染表格之类的。
