element-ui 动态表单_elementui动态表单

背景：朋友入职新公司，做项目重构，根据后端返回表单内容，动态生成表单，于是自己实现了下，哪里写的不好，欢迎各位提建议：

因为开关和多选框默认值是非空字符串，所以在created生命周期单独处理了下

<template>
  <div class="home">
    <el-form ref="form" :model="form" label-width="80px">
      <el-form-item v-for="(item,index) in list" :key="index" :label="item.label">
        <el-input v-if="item.type === 'input'" v-model="form[item.key]"></el-input>
        <el-select v-if="item.type === 'select'" v-model="form[item.key]" placeholder="请选择活动区域">
          <el-option v-for="element in item.select" :key="element.label" :label="element.label" :value="element.value"></el-option>
        </el-select>
        <el-date-picker v-if="item.type === 'date-picker'" type="date" placeholder="选择日期" v-model="form[item.key]" style="width: 100%;"></el-date-picker>
        <el-switch v-if="item.type === 'switch'" v-model="form[item.key]"></el-switch>
        <el-checkbox-group v-if="item.type === 'checkbox-group'" v-model="form[item.key]">
