本文實(shí)例講述了vue多次循環(huán)操作。分享給大家供大家參考，具體如下：
需求：有以下一個(gè)數(shù)組，想將其對(duì)象里的信息展示出來，而且還要把對(duì)象下面的數(shù)組的具體信息也展示出來。v-for可以實(shí)現(xiàn)循環(huán)，但是能否再下一級(jí)進(jìn)行渲染呢？答案是可以的。
list: [{ "scheme_id": "1", "scheme_sn": "2018031416442200001", "scheme_name": "測(cè)試支付寶", "type": "", "field_id": "0", "user_id": "5", "mother_id": "0", "content": "測(cè)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(cè)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(fā)撒", "type": "", "field_id": "0", "user_id": "5", "mother_id": "0", "content": "阿斯達(dá)", "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(cè)試多個(gè)程序方案贈(zèng)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(huán)大的list 然后再用items in item.programs 去循環(huán)對(duì)象里面的數(shù)組
