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.jb51.net 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>
