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> <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
