element-ui動(dòng)態(tài)添加表單項(xiàng)并實(shí)現(xiàn)事件觸發(fā)驗(yàn)證代碼示例
更新時(shí)間：2023年12月15日 08:25:34 作者：reason.
這篇文章主要給大家介紹了關(guān)于element-ui動(dòng)態(tài)添加表單項(xiàng)并實(shí)現(xiàn)事件觸發(fā)驗(yàn)證的相關(guān)資料,其實(shí)就是利用了vue的v-for循環(huán)渲染,通過添加數(shù)組實(shí)現(xiàn)動(dòng)態(tài)添加表單項(xiàng),需要的朋友可以參考下
需求分析：
點(diǎn)擊新增后新增一個(gè)月度活動(dòng)詳情，提交時(shí)可同時(shí)提交多個(gè)月度活動(dòng)詳情。點(diǎn)擊某一個(gè)月度活動(dòng)信息的刪除后可刪除對(duì)應(yīng)月度活動(dòng)信息
