uniapp计算两个时间戳相差的天数代码

function getDaysBetween(startTimestamp, endTimestamp) {
  const ONE_DAY_TIMESTAMP = 24 * 60 * 60 * 1000; // 一天的毫秒数
  const startDay = new Date(startTimestamp);
  const endDay = new Date(endTimestamp);
  const diff = endDay - startDay;
  const days = Math.floor(diff / ONE_DAY_TIMESTAMP);
  return days;
}
