内容图文
本文实例讲述了vue多次循环操作。分享给大家供大家参考，具体如下：
需求：有以下一个数组，想将其对象里的信息展示出来，而且还要把对象下面的数组的具体信息也展示出来。v-for可以实现循环，但是能否再下一级进行渲染呢？答案是可以的。
list: [{
"scheme_id": "1",
"scheme_sn": "2018031416442200001",
"scheme_name": "测试支付宝",
"type": "",
"field_id": "0",
"user_id": "5",
"mother_id": "0",
"content": "测试支付宝",
"program_id": "1,2",
"status": "1",
"range": "1",
"obj": "5",
"add_time": "2018-03-14 16:44:22",
"is_handsel": "2",
"atten_del": "",
"up_time": null,
"obj_phone": "13521121232",
"programs": [{
"program_id": "1",
"reserve": "99701",
"program_name": "测试支付宝1",
"price": "0.0100",
"sale_num": "200"
}, {
"program_id": "2",
"reserve": "4895",
"program_name": "阿萨打算",
"price": "0.0200",
"sale_num": null
}]
}, {
"scheme_id": "2",
"scheme_sn": "2018031416512800002",
"scheme_name": "阿散发撒",
"type": "",
"field_id": "0",
"user_id": "5",
"mother_id": "0",
"content": "阿斯达",
"program_id": "2,3",
"status": "2",
"range": "1",
"obj": "5",
"add_time": "2018-03-14 16:51:28",
"is_handsel": "2",
"atten_del": "",
"up_time": null,
"obj_phone": "13521121232",
"programs": [{
"program_id": "2",
"reserve": "4895",
"program_name": "阿萨打算",
"price": "0.0200",
"sale_num": null
}, {
"program_id": "3",
"reserve": "10",
"program_name": "测试多个程序方案赠送1",
"price": "0.0000",
"sale_num": null
}]
}]
HTML部分：
<div id="app">
<div v-for ="item in list">
<p>{{item.scheme_sn}}</p>
<p v-for="items in item.programs">程序id {{items.program_id}}</p>
<p v-for="items in item.programs">程序名称 {{items.program_name}}</p>
</div>
</div>
先循环大的list 然后再用items in item.programs 去循环对象里面的数组
完整测试示例：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>www.gxlcms.com vue多次循环</title>
<style>
*{
margin: 0;
padding: 0;
list-style: none;
}
</style>
</head>
<body>
<div id="app">
<div v-for ="item in list">
<p>{{item.scheme_sn}}</p>
<p v-for="items in item.programs">程序id {{items.program_id}}</p>
<p v-for="items in item.programs">程序名称 {{items.program_name}}</p>
</div>
</div>
</body>
