React日期选择器返回所有数据，但仅应返回一天

import React, { useState } from 'react';
import DatePicker from 'react-datepicker';
import 'react-datepicker/dist/react-datepicker.css';

const [selectedDate, setSelectedDate] = useState(null);

<DatePicker
  selected={selectedDate}
  onChange={date => setSelectedDate(date)}
  minDate={new Date()}
  maxDate={new Date()}
/>

const handleButtonClick = () => {
  if (selectedDate) {
    // 处理所选日期的数据
    console.log(selectedDate);
  } else {
    // 提示用户选择日期
    console.log('请选择日期');
  }
};
