我可以使用MomentJs得到两个日期之间的差异,如下所示:

moment(end.diff(startTime)).format("m[m] s[s]")

但是,我还想在适用的情况下显示小时(仅当>= 60分钟已经过时)。

然而,当我试图检索持续时间小时使用以下:

var duration = moment.duration(end.diff(startTime));
var hours = duration.hours();

它返回当前的小时数,而不是两个日期之间的小时数。

我如何得到两个时刻之间的小时差?


当前回答

你所需要做的就是把hours作为第二个参数传递给moments diff函数。

var a = moment([21,30,00], "HH:mm:ss")
var b = moment([09,30,00], "HH:mm:ss")
a.diff(b, 'hours') // 12

例子:

const dateFormat = "YYYY-MM-DD HH:mm:ss"; // Get your start and end date/times const rightNow = moment().format(dateFormat); const thisTimeYesterday = moment().subtract(1, 'days').format(dateFormat); // pass in hours as the second parameter to the diff function const differenceInHours = moment(rightNow).diff(thisTimeYesterday, 'hours'); console.log(`${differenceInHours} hours have passed since this time yesterday`); <script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.20.1/moment.min.js"> </script>

我知道这个问题已经回答了,但如果你想要递归的更通用的东西,不依赖于moment fromNow,你可以使用我创建的这个函数。当然,您可以根据需要更改其逻辑,使其支持年和秒。

var createdAt = moment('2019-05-13T14:23:00.607Z');
var expiresAt = moment('2019-05-14T14:23:00.563Z');

// You can also add years in the beginning of the array or seconds in its end
const UNITS = ["months", "weeks", "days", "hours", "minutes"]
function getValidFor (createdAt, expiresAt, unit = 'months') {
    const validForUnit = expiresAt.diff(createdAt, unit);
    // you could adjust the if to your needs 
    if (validForUnit > 1 || unit === "minutes") {
    return [validForUnit, unit];
  }
  return getValidFor(createdAt, expiresAt, UNITS[UNITS.indexOf(unit) + 1]);
}
 calcDifferential(from, to) {
      const fromTime = this.$moment(from, 'hh:mm:ss')
      const toTime = this.$moment(to, 'hh:mm:ss')
      const ms = toTime.diff(fromTime)
      const d = this.$moment.duration(ms)
      const s = d.format()
      return s
    }

下面的代码块展示了如何使用MomentJS计算两个日期之间的天数差异。

var now = moment(new Date()); //todays date
var end = moment("2015-12-1"); // another date
var duration = moment.duration(now.diff(end));
var days = duration.asDays();
console.log(days)
var __startTime = moment("2016-06-06T09:00").format();
var __endTime = moment("2016-06-06T21:00").format();

var __duration = moment.duration(moment(__endTime).diff(__startTime));
var __hours = __duration.asHours();
console.log(__hours);
