<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
