vue+element实现动态加载表单

//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"text-align: center">

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
