2两个时间计算时间差(到天,时,分,秒)

复制代码//计算方法
function getDuration(my_time) {
  var days = my_time / 1000 / 60 / 60 / 24;
  var daysRound = Math.floor(days);
  var hours = my_time / 1000 / 60 / 60 - (24 * daysRound);
  var hoursRound = Math.floor(hours);
  var minutes = my_time / 1000 / 60 - (24 * 60 * daysRound) - (60 * hoursRound);
  var minutesRound = Math.floor(minutes);
  var seconds = my_time / 1000 - (24 * 60 * 60 * daysRound) - (60 * 60 * hoursRound) - (60 * minutesRound);
  var time = daysRound + '天' + hoursRound + '时' + minutesRound + '分' + seconds + '秒'
  return time
}

//执行方法
var date1 = '2021-03-07 20:34:57'
var date2 = '2021-03-08 20:24:27'
var my_time = new Date(date2).getTime()-new Date(date1).getTime();
console.log('计算结果：',getDuration(my_time))
