vue ts element 下的表单验证包括深层验证

代码如下

<template>
  <div>
    <div class="common-wrapper">
      <el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" class="demo-ruleForm">
        <el-form-item label="活动时间" required>
          <el-col :span="11">
            <el-form-item prop="date1">
              <el-date-picker type="date" placeholder="选择日期" v-model="ruleForm.date1" style="width: 100%;"></el-date-picker>
            </el-form-item>
          </el-col>
          <el-col class="line" :span="2">-</el-col>
          <el-col :span="11">
            <el-form-item prop="date2">
