使用 React DayPicker 获取特定一周的日期数组

Question

我希望能够单击反应 DayPicker 中的特定周数，并将该周包含的所有日期的数组返回给我。

我正在使用这个 DayPicker 包： https ://react-day-picker.js.org/

我已经从 react dayPicker 复制了示例代码，以允许我单击一个月中的特定周： https ://react-day-picker.js.org/basics/customization

import { useState } from 'react'
import { DayPicker } from 'react-day-picker'

export const WeekPicker = () => {

  const [weekNumber, setWeekNumber] = useState()
  const footer = weekNumber
    ? `You clicked the week n. ${weekNumber}.`
    : 'Try clicking a week number.'

  

  return (
    <DayPicker
      showWeekNumber
      onWeekNumberClick={setWeekNumber}
      footer={footer}
    />
  )
}

我可以在 EventHandlers.d.ts 文件中看到一个 WeekNumberClickEventHandler 变量名为 dates 但是我只能访问 weekNumber 变量

/**The event handler when the week number is clicked. */
export declare type WeekNumberClickEventHandler = (
/** The week number that has been clicked. */
weekNumber: number, 
/** The dates in the clicked week. */
dates: Date[], 
/** The mouse event that triggered this event. */
e: React.MouseEvent) => void;

任何帮助，将不胜感激。 我正在用 JS 编码，但我意识到 DayPicker 包是用 TS 编写的。

日期是回调中的第二个参数

import { useState } from 'react'
import { DayPicker } from 'react-day-picker'

export const WeekPicker = () => {

  const [weekNumber, setWeekNumber] = useState()
  const footer = weekNumber
    ? `You clicked the week n. ${weekNumber}.`
    : 'Try clicking a week number.'

  

  return (
    <DayPicker
      showWeekNumber
      onWeekNumberClick={(weekNumber, dates) => {
        setWeekNumber(weekNumber);
        console.log(dates)
      }}
      footer={footer}
    />
  )
}
