我是靠谱客的博主负责小熊猫，最近开发中收集的这篇文章主要介绍vue+element实现动态加载表单，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

本文实例为大家分享了vue+element实现动态加载表单的具体代码，供大家参考，具体内容如下

一、问卷动态加载表单

//html
<el-form :model="quesPaper" status-icon label-width="100px" label-position="top" size="small" v-loading="paperLoading" >  
 <el-form-item
 v-for="n in paperForm.answerList"
 :label="n.questionRepository.question"
 :key="n.key"
 >
 <!-- 单选 -->
 <el-radio-group v-model="n.optionId" v-if="n.questionRepository.type === 1">
 <el-radio v-for="(i, idx) in n.questionOption" :label="i.id" :key="idx" class="mb5">{{ i.questionOption }}</el-radio>
 </el-radio-group>
 <!-- 多选 -->
 <el-checkbox-group v-model="n.optionId" v-if="n.questionRepository.type === 2">
 <el-checkbox v-for="(i, idx) in n.questionOption" :label="i.id" :key="idx">{{ i.questionOption }}</el-checkbox>
 </el-checkbox-group>
 <!-- 填空 -->
 <el-input type="textarea" style="width: 600px" class="fl" v-model="n.answer" v-if="n.questionRepository.type === 3" :rows="4" placeholder="请输入内容" ></el-input>
 </el-form-item>


 <el-row class="mt20" type="flex" justify="start">
 <el-col :span="5">
 <el-button type="primary" size="small" @click.stop="saveStageAnswer">保存问卷</el-button>
 </el-col>
 </el-row>
</el-form>

//data数据
paperForm: { // 问卷表单
 answerList:[{
 questionRepository:'',
 questionOption:[],

 questionId: '',
 optionId:'',
 answer: ''
 }]
 },
//接口
getPaperByDrugStatus(drugStatus, id){ // 根据用药状态获取问卷
 this.paperLoading = true
 this.$axios.get(this.$api + 'xxx/xxx?paperId='+this.selectStage.paperId + '&drugStatus=' + drugStatus).then(res => {
 if(res.data.code === 200){
 let answerArr = []
 let questionArr = []
 res.data.data.questionToList.map((item)=>{
 item.optionList.map((n)=>{
  questionArr.push({
  id:n.id,
  questionOption:n.questionOption
  })
 })
 answerArr.push({
  questionOption:questionArr,
  questionRepository:item.questionRepository,

  questionId:item.questionRepository.id,
  optionId:item.questionRepository.type === 2?[]:'',
  answer: ''
 })
 })
 console.log(answerArr)
 this.paperForm = { // 问卷表单
 answerList:answerArr
 }
 setTimeout(() => {
 this.paperLoading = false
 }, 300)
 }
 })
},

二、批量数据动态加载表单

特点：

1.每一行的输入框，根据后台返回值，动态生成，数量可增可减。
2.行数根据自己设置的值 5 ，自动循环生成。
3.验证需要:prop和:rules，如果不验证，就删了

<template>
<!-- 录入数据 -->
 <div class="DialyInputDetail" >
 <div class="fw fz16 color6 mb20 mt10">批量录入<span class="colorRed">{{tabHeader.monthStr}}</span>数据</div>
 <el-form status-icon label-width="100px" :model="newForm" ref='newForm' label-position="top" size="small"> 
 <table border="1" class="fw fz14 color6 table">
 <tr>
  <td rowspan='2'>患者请用姓名<br/>或病历号模糊筛选</td>
  <td :colspan="tabHeader.firstTables.length" class="tc colorRed lh40">以下信息每1个月登记一次</td>
  <td :colspan="tabHeader.secondTables.length" class="tc colorRed lh40">以下信息每3个月登记一次</td>
  <td :colspan="tabHeader.thirdTables.length" class="tc colorRed lh40">以下信息每6个月登记一次</td>
 </tr>
 <tr class="lh40">
  <td v-for="item in tabHeader.firstTables" :key="item.name" class="tc">{{item.name}}</td>
  <td v-for="n in tabHeader.secondTables" :key="n.name" class="tc">{{n.name}}</td>
  <td v-for="z in tabHeader.thirdTables" :key="z.nam" class="tc">{{z.name}}</td>
 </tr>
 
 <tr v-for="(w,index) in newForm.colList" :key="index+'a'" >
  <td> 
  <el-form-item
  :prop="'colList.'+index+'.patientId'"
  >
  <!--- :rules="{required: true, message: '不能为空', trigger: 'blur'}"-->
  <el-select v-model="w.patientId" size="small" style="width: 100px" filterable clearable>
  <el-option
   v-for="(ite, idx) in patientArr"
   :label="ite.patient" 
   :key="idx"
   :value="ite.id">
  </el-option>
  </el-select>
  </el-form-item>
  </td>
  <td class="tc" v-for="(n,j) in w.itemDataList" :key="j">
  <el-form-item
  :prop="'colList.'+index+'.itemDataList.' + j + '.itemValue'"
  >
  <!-- :rules="{required: true, message: '不能为空', trigger: 'blur'}"-->
  <el-select v-model="n.itemValue" size="small" style="width: 100px" v-if="n.type == 2" filterable clearable>
  <el-option
   v-for="(i, idx) in n.opts"
   :label="i" 
   :key="idx"
   :value="i">
  </el-option>
  </el-select>
  <el-input style="width: 100px" size="small" v-model="n.itemValue" v-if="n.type == 1" ></el-input>
  </el-form-item>
  </td>
 </tr>

  <el-button type="primary" size="small" @click="submitNew('newForm')">提交数据</el-button>
 </el-col>
