获取日、小时和分钟的不同时刻js

Question

我有两个日期时间选择器(from，to)。我需要得到开始和结束日期在分钟(1505min)和日期和时间(2天1h 35分钟)之间的差异。

我使用moment.js

var now = moment('2018-03-28 14:02');
var end = moment('2018-06-02 00:00'); // another date
var duration = moment.duration(end.diff(now));
var days = duration.asDays();
console.log(days) //65.41527777777777

这里的输出是65.41527777777777，其中65是正确的天，但如何将41527777777777转换为小时和分钟。如果我做这个0,41527777777777 * 24 = 9,96666666648，我得到9个小时，再一次0,96666666648 * 60 = 57，这是正确的区别

65 day, 9 hour and 57 min

但是，有没有办法直接用moment.js做到这一点呢？

谢谢

Answer 1

不是直接在moment.js中，但是this open issue把我带到了this moment.js plugin，它允许格式化持续时间。看起来你可以使用这个插件来获得你想要的输出：

duration.format("D [day], H [hour and] m [min]")

Answer 2

没有插件：

var now = moment('2018-03-28 14:02');
var end = moment('2018-06-02 00:00'); // another date
var duration = moment.duration(end.diff(now));

//Get Days and subtract from duration
var days = duration.asDays();
duration.subtract(moment.duration(days,'days'));

//Get hours and subtract from duration
var hours = duration.hours();
duration.subtract(moment.duration(hours,'hours'));

//Get Minutes and subtract from duration
var minutes = duration.minutes();
duration.subtract(moment.duration(minutes,'minutes'));

//Get seconds
var seconds = duration.seconds();
console.log("Days: ",days);
console.log("Hours: ",hours);
console.log("Minutes: ",minutes);
console.log("Seconds: ",seconds);

当moment.asDays(date)返回float时，需要使用Math.floor()

​

function durationAsString(start, end) {
  const duration = moment.duration(moment(end).diff(moment(start)));

  //Get Days
  const days = Math.floor(duration.asDays()); // .asDays returns float but we are interested in full days only
  const daysFormatted = days ? `${days}d ` : ''; // if no full days then do not display it at all

  //Get Hours
  const hours = duration.hours();
  const hoursFormatted = `${hours}h `;

  //Get Minutes
  const minutes = duration.minutes();
  const minutesFormatted = `${minutes}m`;

  return [daysFormatted, hoursFormatted, minutesFormatted].join('');
}

console.log(durationAsString('2018-03-28 14:02', '2018-06-02 00:00'))

console.log(durationAsString('2018-06-01 14:02', '2018-06-02 00:00'))
