本文實例講述了vue多次循環操作。分享給大家供大家參考，具體如下：

需求：有以下一個數組，想將其對象里的信息展示出來，而且還要把對象下面的數組的具體信息也展示出來。v-for可以實現循環，但是能否再下一級進行渲染呢？答案是可以的。

list: [{    "scheme_id": "1",    "scheme_sn": "2018031416442200001",    "scheme_name": "測試支付寶",    "type": "",    "field_id": "0",    "user_id": "5",    "mother_id": "0",    "content": "測試支付寶",    "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": "測試支付寶1",      "price": "0.0100",      "sale_num": "200"    }, {      "program_id": "2",      "reserve": "4895",      "program_name": "阿薩打算",      "price": "0.0200",      "sale_num": null    }]  }, {    "scheme_id": "2",    "scheme_sn": "2018031416512800002",    "scheme_name": "阿散發撒",    "type": "",    "field_id": "0",    "user_id": "5",    "mother_id": "0",    "content": "阿斯達",    "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": "阿薩打算",      "price": "0.0200",      "sale_num": null    }, {      "program_id": "3",      "reserve": "10",      "program_name": "測試多個程序方案贈送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">程序名稱 {{items.program_name}}</p>    </div></div>

先循環大的list 然后再用items in item.programs 去循環對象里面的數組
