Get the days, hours and minutes in Moment.js
提问by I am L
So This is my first time using Moment.js and I encountered the following problem, so I have this following dates:
所以这是我第一次使用 Moment.js，我遇到了以下问题，所以我有以下日期：
now: 2017-01-26T14:21:22+0000
expiration: 2017-01-29T17:24:22+0000
What I want to get is:
我想得到的是：
Day: 3
Hours: 3
Mins: 3
I tried the following code:
我尝试了以下代码：
const now = moment();
const exp = moment(expire_date);
console.log(expire_date);
days = exp.diff(now, 'days');
hours = exp.diff(now, 'hours') - (days * 24);
minutes = exp.diff(now, 'minutes') - ((days * 1440) + (hours * 24) * 60);
I know I did something wrong (maybe my calculation or I used the wrong method), but I can't figure out what it is.
我知道我做错了什么（可能是我的计算或我使用了错误的方法），但我无法弄清楚它是什么。

MomentJS can calculate all that for you without you doing any logic.
MomentJS 可以为您计算所有这些，而无需您做任何逻辑。
- First find the difference between the two moments
- Express it as a Duration
- Then display whichever component
.days(),.hours()of the duration that you want.
- 首先找到两个时刻的区别
- 将其表示为持续时间
- 然后显示任何组件中
.days()，.hours()持续时间是你想要的。
Note: You can also express the entire duration .asDays(), .asHours()etc if you want.
注意：如果需要.asDays()，您还可以表达整个持续时间.asHours()等。
const now = moment("2017-01-26T14:21:22+0000");
const expiration = moment("2017-01-29T17:24:22+0000");
// get the difference between the moments
const diff = expiration.diff(now);
//express as a duration
const diffDuration = moment.duration(diff);
// display
console.log("Days:", diffDuration.days());
console.log("Hours:", diffDuration.hours());
console.log("Minutes:", diffDuration.minutes());<script src="https://momentjs.com/downloads/moment.js"></script>回答by alebianco
this will give you the right values and remove the headache of manual calculations
这将为您提供正确的值并消除手动计算的麻烦
let expiration = "2017-01-29T17:24:22+0000"
const now = moment();
const exp = moment(expiration);
console.log(exp.format());
days = exp.diff(now, 'days');
hours = exp.subtract(days, 'days').diff(now, 'hours');
minutes = exp.subtract(hours, 'hours').diff(now, 'minutes');
console.log(days, hours, minutes)<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.17.1/moment.min.js"></script>note that the substractoperations will mutate the original expvalue, so don't go passing it around expecting it to be the original date
请注意，这些substract操作会改变原始exp值，因此不要期望它是原始日期而传递它

Try my solution. I think that is it:
试试我的解决方案。我认为就是这样：
var now = moment("2017-01-26T14:21:22+0000");
var expiration = moment("2017-01-29T17:24:22+0000");
var minsAverage = expiration.diff(now, "minutes");
var min = parseInt(minsAverage % 60);
var hours = parseInt(minsAverage / 60);
var days = parseInt(hours / 24);
hours = hours - 24*days;

var now = moment()
var exp = moment().add(1,'days')
var days = exp.diff(now, 'days')
var months = exp.diff(now, 'months')
var years = exp.diff(now, 'years', true) //float number
