获取Moment Js中两个日期之间的小时差异

本文翻译自：Get hours difference between two dates in Moment Js

I'm able to get the difference between two dates using MomentJs as follows: 我可以使用MomentJs获得两个日期之间的差异，如下所示：

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

However, I also want to display the hour when applicable (only when >= 60 minutes have passed). 但是，我也希望在适用时显示小时（仅当> = 60分钟时才显示）。

However, when I try to retrieve the duration hours using the following: 但是，当我尝试使用以下内容检索持续时间时：

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

it is returning the current hour and not the number of hours between the two dates. 它返回当前小时而不是两个日期之间的小时数。

How do I get the difference in hours between two Moments? 如何获得两个时刻之间的小时差异？

You were close. 你很亲密 You just need to use the duration.asHours() method (see the docs ). 您只需要使用duration.asHours()方法（请参阅文档 ）。

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

Following code block shows how to calculate the difference in number of days between two dates using MomentJS. 以下代码块显示了如何使用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)

Or you can do simply: 或者你可以做到：

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

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);
