怎么在vue中實現多次循環操作？很多新手對此不是很清楚，為了幫助大家解決這個難題，下面小編將為大家詳細講解，有這方面需求的人可以來學習下，希望你能有所收獲。
Vue是一套用于構建用戶界面的漸進式JavaScript框架，Vue與其它大型框架的區別是，使用Vue可以自底向上逐層應用，其核心庫只關注視圖層，方便與第三方庫和項目整合，且使用Vue可以采用單文件組件和Vue生態系統支持的庫開發復雜的單頁應用。
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",

}, {

"price": "0.0200",

}]
}, {

"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
