vue element el-form 多級嵌套驗(yàn)證的實(shí)現(xiàn)示例
更新時(shí)間：2022年08月12日 11:52:54 作者：zhang070514
本文主要介紹了vue element el-form 多級嵌套驗(yàn)證的實(shí)現(xiàn)示例，文中通過示例代碼介紹的非常詳細(xì)，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧
最近在做項(xiàng)目時(shí)遇到這樣一個(gè)需求，一個(gè)form表單里面有兩個(gè)字段數(shù)量不固定，可以動(dòng)態(tài)的增刪，在提交的時(shí)候不管數(shù)量有多少都需要驗(yàn)證，頁面效果如下：
form表單對應(yīng)的數(shù)據(jù)結(jié)構(gòu)如下:
voucherInfo: {
cash: [
{
cashNum: '', // 押金流水號
cashPayType: null, // 押金支付類型
}
],
cashPayTime: '', // 押金支付時(shí)間
cashPayVoucher: [], // 押金支付憑證
commissionNum: '', // 傭金流水號
commissionPayType: null, // 傭金支付方式
commissionPayTime: '', // 傭金支付時(shí)間
commissionPayVoucher: [], // 傭金支付憑證
remark: '' // 備注
}
在這里主要考慮的就是如何驗(yàn)證voucherInfo的第一個(gè)字段，它是一個(gè)數(shù)組，數(shù)組里面又是一個(gè)對象，我們要驗(yàn)證這個(gè)對象的每個(gè)屬性，簡而言之，就是驗(yàn)證對象里面的數(shù)組里面的對象屬性。
方法一：el-form里面再嵌套一個(gè)el-form
<el-form
ref="voucherForm"
:rules="voucherRule"
:model="voucherInfo"
label-width="140px"
>
<div
v-for="(item, index) in voucherInfo.cash"
:key="index"
>
<!-- 嵌套的el-form model綁定的是voucherInfo.cash里面的對象 -->
<!-- 又定義了一個(gè)rules :rules="subVoucherRule"-->
<el-form
ref="subVoucherForm"
:model="item"
:rules="subVoucherRule"
label-width="140px"

<el-row>
<el-col :span="6">

驗(yàn)證規(guī)則：
voucherRule: {
cashPayTime: [{ required: true, message: '請選擇押金支付時(shí)間', trigger: 'change'}],
cashPayVoucher: [{ required: true, message: '請上傳押金支付憑證', trigger: 'change'}],
commissionNum: [{ required: true, message: '請輸入傭金流水號', trigger: 'blur'}],
commissionPayType: [{ required: true, message: '請選擇傭金支付方式', trigger: 'change'}],
commissionPayTime: [{ required: true, message: '請選擇傭金支付時(shí)間', trigger: 'change'}],
commissionPayVoucher: [{ required: true, message: '請上傳傭金支付憑證', trigger: 'change'}],
},
subVoucherRule: {
cashNum: [{ required: true, message: '請輸入押金流水號', trigger: 'blur'}],
cashPayType: [{ required: true, message: '請選擇押金支付方式', trigger: 'change'}],
}
提交時(shí)驗(yàn)證代碼：因?yàn)橛袃蓚€(gè)form，所以兩個(gè)都需要驗(yàn)證
