格式化日期并向其添加月份

// 格式化日期并添加月份
function formatDateAndAddMonth(date, format, months) {
  const year = date.getFullYear();
  const month = date.getMonth() + 1;
  const day = date.getDate();

  // 格式化日期
  let formattedDate = format
    .replace('YYYY', year)
    .replace('MM', month.toString().padStart(2, '0'))
    .replace('DD', day.toString().padStart(2, '0'));

  // 添加月份
  const newDate = new Date(date);
  newDate.setMonth(newDate.getMonth() + months);

  return {
    formattedDate,
    newDate
  };
}

// 示例用法
const date = new Date();
const format = 'YYYY-MM-DD';
const monthsToAdd = 3;

const result = formatDateAndAddMonth(date, format, monthsToAdd);
console.log('Formatted Date:', result.formattedDate);
console.log('New Date:', result.newDate);
