鲁迅HH:日期间的差异

Question

用鲁迅代替瞬间，并希望HH:mm中的日期时间之间的差异。有更好的方法吗？

const DateTime = luxon.DateTime;
const Interval = luxon.Interval;

const format1 = "yyyy-MM-dd HH:mm";
var time1 = '2021-11-22 10:11';
var time2 = '2021-11-22 16:12';
var start = DateTime.fromFormat(time1,format1);
var end =  DateTime.fromFormat(time2,format1);
var diff = end.diff(start);
var i = Interval.fromDateTimes(start, end);
var sec = i.length('seconds') ;
var hours = Math.floor(sec / 60 / 60);
var minutes = Math.floor(sec / 60) - (hours * 60);
var formatted = hours.toString().padStart(2, '0') + ':' + minutes.toString().padStart(2, '0'); //"HH:mm"
alert(formatted); //06:01

Answer 1

end.diff(start, "seconds", "minutes").toFormat("hh:mm"); // => 6:01

Answer 2

您可以使用duration.toFormat()实现相同的结果。使用功能应用程序：

​

const {DateTime} = luxon;

function parseDT (dt, format = 'yyyy-MM-dd HH:mm') {
  // You can optionally implement any datetime string validation here
  return DateTime.fromFormat(dt, format);
}

function getDurationString (dt1, dt2, format = 'hh:mm') {
  return parseDT(dt2).diff(parseDT(dt1)).toFormat(format);
}

console.log(getDurationString('2021-11-22 10:11', '2021-11-22 16:12')); // 06:01
console.log(getDurationString('2021-11-01 10:00', '2021-12-01 10:00')); // 721:00
