vue3 antdv3 a-range-picker a-date-picker 获取选择中的日期值

1、经常用到日期选择、日期范围选择控制

Ant Design Vue --- An enterprise-class UI components based on Ant Design and Vue.js

2、上代码：

<RangePicker
        v-model:value="fieldvaluedate"
        style="width: 250px"
        :placeholder="['选择日期', '选择日期']"
        format="YYYY-MM-DD"
        @change="onRangePickerChange"
      />
      <DatePicker
        v-model:value="fieldvaluedate1"
        style="width: 250px"
        placeholder="选择日期"
        format="YYYY-MM-DD"
        @change="onDatePickerChange"
      />

  function onRangePickerChange(value, dateString) {
    fieldvalue = dateString[0] + ',' + dateString[1];
  }

  function onDatePickerChange(value, dateString) {
    fieldvalue = dateString;
  }

import { DatePicker, RangePicker } from 'ant-design-vue';

fieldvalue: '',
fieldvaluedate: ref<[Dayjs, Dayjs]>(),
fieldvaluedate1: ref<Dayjs>(),

 import dayjs, { Dayjs } from 'dayjs';
  import weekday from 'dayjs/plugin/weekday';
  import localeData from 'dayjs/plugin/localeData';
  dayjs.extend(weekday);
  dayjs.extend(localeData);

3、上面的代码，要适当的调整下，就可以使用了。
