如何用momentjs检查过去的日期是否至少一天？

Question

How does one generally check if a random date is at least one day (24hrs) in the past with momentjs?

Something like:

const today = moment()
const isAtLeastADayAgo = today.subtract(dateToCheck) > 1 // ??

Answer 1

You can simply use isBefore

 function isADayAgo(input){ let yesterday = moment().subtract(1, 'd'); return input.isBefore(yesterday); } const isAtLeastADayAgo = isADayAgo(moment()); console.log(isAtLeastADayAgo); 

 <script src="//cdnjs.cloudflare.com/ajax/libs/moment.js/2.17.1/moment.min.js"></script> 

Or you can use diff limiting granularity to days:

 const today = moment(); const dateToCheck = moment().subtract(3, 'd'); const isAtLeastADayAgo = today.diff(dateToCheck, 'd') > 1; console.log(isAtLeastADayAgo);

Answer 2

i would suggest you to do it with plain javascript Date constructor.

var today =  new Date();
var pastDate = // some past date
// 86400 seconds in 24hrs
// getTime() will return you date in milliseconds
if(86400000 < today.getTime()-pastDate.getTime()) will return true if past date is older than 24Hrs.

Answer 3

const isAtLeastADayAgo = moment().subtract(1,'days')>dateToCheck
