如果你想要两个日期(startDate, endDate)之间的本地化天数:

var currentLocaleData = moment.localeData("en");
var duration = moment.duration(endDate.diff(startDate));
var nbDays = Math.floor(duration.asDays()); // complete days
var nbDaysStr = currentLocaleData.relativeTime(returnVal.days, false, "dd", false);

nbDaysStr将包含类似“3天”的内容;

例如，有关如何显示小时数或月数的信息，请参阅https://momentjs.com/docs/#/i18n/changing-locale/。

你的问题是在格式化moment.duration()之前将结果传递回moment();这将导致moment()将其解释为相对于Unix epoch的时间。

它并没有给你你想要的格式，但是

moment.duration (now.diff(当时).humanize ()

会给你一个有用的格式，比如“40分钟”。如果你真的热衷于特定的格式，你必须自己构建一个新的字符串。一个便宜的方法是

[diff.asHours (), diff.minutes (), diff.seconds ()] . join(“:”)

var diff = moment.duration(now.diff(then))。这不会给你个位数值的零填充。为此，您可能需要考虑使用下划线之类的东西。字符串——尽管它看起来有很长的路要走，只是为了多几个0。：）

我用typescript创建了一个简单的函数

const diffDuration: moment.Duration = moment.duration(moment('2017-09-04 12:55').diff(moment('2017-09-02 13:26')));
setDiffTimeString(diffDuration);

function setDiffTimeString(diffDuration: moment.Duration) {
  const str = [];
  diffDuration.years() > 0 ? str.push(`${diffDuration.years()} year(s)`) : null;
  diffDuration.months() > 0 ? str.push(`${diffDuration.months()} month(s)`) : null;
  diffDuration.days() > 0 ? str.push(`${diffDuration.days()} day(s)`) : null;
  diffDuration.hours() > 0 ? str.push(`${diffDuration.hours()} hour(s)`) : null;
  diffDuration.minutes() > 0 ? str.push(`${diffDuration.minutes()} minute(s)`) : null;
  console.log(str.join(', '));
} 
// output: 1 day(s), 23 hour(s), 29 minute(s)

生成javascript https://www.typescriptlang.org/play/index.html

这将返回最大的时间周期差异，如(4秒，2分钟，1小时，2天，3周，4个月，5年)。 我用这个来通知最近的时间。

function dateDiff(startDate, endDate) {
    let arrDate = ["seconds", "minutes", "hours", "days", "weeks", "months", "years"];
    let dateMap = arrDate.map(e => moment(endDate).diff(startDate, e));
    let index = 6 - dateMap.filter(e => e == 0).length;
    return {
        type: arrDate[index] ?? "seconds",
        value: dateMap[index] ?? 0
    };
}

例子:

dateDiff("2021-06-09 01:00:00", "2021-06-09 04:01:01")

{type: "hours", value: 3}

dateDiff("2021-06-09 01:00:00", "2021-06-12 04:01:01")

{type: "days", value: 3}

dateDiff("2021-06-09 01:00:00", "2021-06-09 01:00:10")

{type: "seconds", value: 10}

亲密的= 06:38 Outtime = 15:40

 calTimeDifference(){
        this.start = dailyattendance.InTime.split(":");
        this.end = dailyattendance.OutTime.split(":");
        var time1 = ((parseInt(this.start[0]) * 60) + parseInt(this.start[1]))
        var time2 = ((parseInt(this.end[0]) * 60) + parseInt(this.end[1]));
        var time3 = ((time2 - time1) / 60);
        var timeHr = parseInt(""+time3);
        var  timeMin = ((time2 - time1) % 60);
    }

这应该可以正常工作。

var now  = "04/09/2013 15:00:00";
var then = "02/09/2013 14:20:30";

var ms = moment(now,"DD/MM/YYYY HH:mm:ss").diff(moment(then,"DD/MM/YYYY HH:mm:ss"));
var d = moment.duration(ms);

console.log(d.days() + ':' + d.hours() + ':' + d.minutes() + ':' + d.seconds());
