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

 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
    }

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

文档:https://momentjs.com/docs/ # / /显示/不同

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>

根据Moment JS的新Deprecation警告

你需要传递开始和结束日期格式的格式以及值,例如:

   let trackStartTime = "2020-12-29 09:59:19.07 +05:30";
   let trackEndTime = "2020-12-29 11:04:19.07 +05:30" || moment().format("YYYY-MM-DD HH:mm:ss.SS Z");
   let overallActivity = moment.duration(moment(trackEndTime, 'YYYY-MM-DD HH:mm:ss.SS Z').diff(moment(trackStartTime, 'YYYY-MM-DD HH:mm:ss.SS Z'))).asHours();
 var start=moment(1541243900000);
 var end=moment(1541243942882);
 var duration = moment.duration(end.diff(startTime));
 var hours = duration.asHours();

如您所见,开始日期和结束日期需要是此方法工作的时刻对象。

            var timecompare = {
            tstr: "",
            get: function (current_time, startTime, endTime) {
                this.tstr = "";
                var s = current_time.split(":"), t1 = tm1.split(":"), t2 = tm2.split(":"), t1s = Number(t1[0]), t1d = Number(t1[1]), t2s = Number(t2[0]), t2d = Number(t2[1]);

                if (t1s < t2s) {
                    this.t(t1s, t2s);
                }

                if (t1s > t2s) {
                    this.t(t1s, 23);
                    this.t(0, t2s);
                }

                var saat_dk = Number(s[1]);

                if (s[0] == tm1.substring(0, 2) && saat_dk >= t1d)
                    return true;
                if (s[0] == tm2.substring(0, 2) && saat_dk <= t2d)
                    return true;
                if (this.tstr.indexOf(s[0]) != 1 && this.tstr.indexOf(s[0]) != -1 && !(this.tstr.indexOf(s[0]) == this.tstr.length - 2))
                    return true;

                return false;

            },
            t: function (ii, brk) {
                for (var i = 0; i <= 23; i++) {
                    if (i < ii)
                        continue;
                    var s = (i < 10) ? "0" + i : i + "";
                    this.tstr += "," + s;
                    if (brk == i)
                        break;
                }
            }};
 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
    }
