二、查看引入DatetimePicker步骤

具体代码如下：
<template>
  <div>
    <div class="birth">
      <div @click="openPicker1">{{startText}}</div>
      <div @click="openPicker2">{{endText}}</div>
    </div>
    <div class="datePicker">
      <mt-datetime-picker
        type="date"
        ref="picker1"
        year-format="{value} 年"
        month-format="{value} 月"
        date-format="{value} 日"
        @confirm="handleConfirm1"
        :startDate="startDate"
        v-model="dateVal"
            >
        </mt-datetime-picker>
        <mt-datetime-picker
        type="date"
        ref="picker2"
        year-format="{value} 年"
        month-format="{value} 月"
        date-format="{value} 日"
        @confirm="handleConfirm2"
        :startDate="startDate"
        v-model="dateVal"
            >
        </mt-datetime-picker>
    </div>
  </div>
</template>

<script>
