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。

Answer 1

MomentJS可以在不做任何逻辑的情况下为你计算所有这些。

首先找出两个时刻之间的区别
将其表示为持续时间
然后显示您想要的持续时间的.days()，.hours()组件。

注意：如果需要，您还可以表达整个期限.asDays()，.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());

Answer 2

这将为您提供正确的值并消除手动计算的麻烦

＆＃13;

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)

请注意，substract操作会改变原来的exp值，因此请不要将其传递给期望它是原始日期

Answer 3

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;

Answer 4

有关详细信息，请查看文档https://momentjs.com/docs/#/displaying/difference/

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

console.log(now,exp,days, months, years)
