vue element 動態增加表單並進行表單驗證

 

 

表單驗證：
需要注意的一點是：

普通表單驗證單項依靠的是prop…而動態生成的表單要用:prop

書寫的語法是:prop="‘moreNotifyObject.’ + index +’.notifyobject’"，moreNotifyObject是v-for綁定的數組，index是索引，notifyobject是表單綁定的v-model的名稱，然後用.把他們鏈接起來。

所以總結起來的語法就是:prop="‘v-for綁定的數組.’ + index + ‘.v-model綁定的變量’"

還有一個需要注意就是v-for的寫法，要將表單的model名寫進去

<div class="moreRulesIn" v-for="(item, index) in addForm.moreNotifyObject" :key="item.key">

 

 

<template>
  <div>
    <el-form ref="form" :model="addForm" label-width="80px">
      <div class="moreRules">
        <div
          class="moreRulesIn"
          v-for="(item, index) in addForm.moreNotifyObject"
          :key="item.key"
        >
          <el-row>
            <el-col :span="6">
              <el-form-item
                label="field"
                :prop="'moreNotifyObject.' + index + '.field'"
                :rules="[{ required: true, message: '請完善信息' }]"
              >
                <el-input
                  v-model="item.field"
                  placeholder="請輸入field"
                  class="el-select_box"
                ></el-input>
              </el-form-item>
            </el-col>
            <el-col :span="6">

                :rules="[{ required: true, message: '請完善信息' }]"
              >
                <el-input
