使用 React DayPicker 獲取特定一周的日期數組

Question

我希望能夠單擊反應 DayPicker 中的特定周數，並將該周包含的所有日期的數組返回給我。

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

我已經從 react dayPicker 復制了示例代碼，以允許我單擊一個月中的特定周： 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 文件中看到一個 WeekNumberClickEventHandler 變量名為 dates 但是我只能訪問 weekNumber 變量

/**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;

任何幫助，將不勝感激。 我正在用 JS 編碼，但我意識到 DayPicker 包是用 TS 編寫的。

日期是回調中的第二個參數

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}
    />
  )
}
