获取Moment.js中的日,小时和分钟

Question

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

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(也许是我的计算或者我使用了错误的方法),但我无法弄清楚它是什么.

MomentJS可以为您计算所有这些,而无需您做任何逻辑.

• 首先找出两个时刻之间的区别
• 将其表示为持续时间
• 然后显示任何组件中.days(),.hours()所需的持续时间.

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());
