从给定日期开始计算3个工作日时捕获假期

function calculateWorkingDays(startDate, numDays) {
  var currentDate = new Date(startDate);
  var holidays = [/* 假期列表 */];

  while (numDays > 0) {
    currentDate.setDate(currentDate.getDate() + 1);

    if (isWorkingDay(currentDate) && !isHoliday(currentDate, holidays)) {
      numDays--;
    }
  }

  return currentDate;
}

function isWorkingDay(date) {
  // 判断日期是否为周末（周六或周日）
  return date.getDay() !== 0 && date.getDay() !== 6;
}

function isHoliday(date, holidays) {
  // 判断日期是否为假期
  return holidays.includes(date.toISOString().split('T')[0]);
}

// 示例用法
var startDate = new Date('2022-01-01');
var numDays = 3;
var result = calculateWorkingDays(startDate, numDays);
console.log(result.toISOString().split('T')[0]);
