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?

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>

或者你可以简单地做:
var a = moment('2016-06-06T21:03:55');//now
var b = moment('2016-05-06T20:03:55');
console.log(a.diff(b, 'minutes')) // 44700
console.log(a.diff(b, 'hours')) // 745
console.log(a.diff(b, 'days')) // 31
console.log(a.diff(b, 'weeks')) // 4
文档:
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);
有一个叫做fromNow()的很棒的moment方法，它会以人类可读的形式返回特定时间的时间，就像这样:
moment('2019-04-30T07:30:53.000Z').fromNow() // an hour ago || a day ago || 10 days ago
或者如果你想在两个特定的日期之间，你可以使用:
var a = moment([2007, 0, 28]);
var b = moment([2007, 0, 29]);
a.from(b); // "a day ago"
摘自文档:
都可以() 从()
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;
}
}};
也许对某人有用
var ax = moment(
new Date().toLocaleString(), // today/now is 09/12/2021 10:00:00
"DD/MM/YYYY HH:mm:ss"
).diff(
moment(
"12/11/2022 13:43:11", // some time in future or past
"DD/MM/YYYY HH:mm:ss"
)
);
console.log('if today is in the future of the compared date then
result should be negative ==>', ax);
// ax bigger than 0 zero means date in past. ms less than zero is in future
