如何查找支付期结束后的下一个星期五

function getNextFridayAfterPaymentDate(paymentDate) {
  // 获取当前日期
  var currentDate = new Date();
  
  // 判断当前日期是否为星期五
  if (currentDate.getDay() === 5) {
    currentDate.setDate(currentDate.getDate() + 7);
  } else {
    // 找到下一个星期五的日期
    var daysUntilNextFriday = (5 - currentDate.getDay() + 7) % 7;
    currentDate.setDate(currentDate.getDate() + daysUntilNextFriday);
  }
  
  return currentDate;
}

// 示例使用
var paymentDate = new Date('2022-01-31');
var nextFriday = getNextFridayAfterPaymentDate(paymentDate);
console.log(nextFriday);
