在Moment.js中获取日期，小时和分钟 [英] Get the days, hours and minutes in Moment.js

问题描述

所以这是我第一次使用Moment.js，遇到了以下问题，所以我有以下日期:

So This is my first time using Moment.js and I encountered the following problem, so I have this following dates:

now: 2017-01-26T14:21:22+0000
expiration: 2017-01-29T17:24:22+0000

我想得到的是:

Day: 3
Hours: 3
Mins: 3

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);

我知道我做错了什么(也许是我的计算或我使用了错误的方法)，但是我无法弄清楚它是什么.

I know I did something wrong (maybe my calculation or I used the wrong method), but I can't figure out what it is.

推荐答案

MomentJS可以为您计算所有内容，而无需您执行任何逻辑.

MomentJS can calculate all that for you without you doing any logic.

• 首先找到两个时刻之间的差异
• 将其表示为持续时间
• 然后显示所需持续时间的任意部分.days()，.hours().

• 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.

注意:如果需要，您还可以表示整个持续时间.asDays()，.asHours()等.

Note: You can also express the entire duration .asDays(), .asHours() etc if you want.

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());
