momentjs 不会在两个日期之间产生差异

Question

我试图在几分钟内获得现在和结束日期之间的差异。 我有两个日期变量，但是当我尝试减去它们时，它说Property 'diff' does not exist on type 'string'.

console.log(now) 输出： November 24th 2019, 11:13:32 :13: November 24th 2019, 11:13:32

console.log(endDate) 输出： November 24th 2019, 12:25:10 :25: November 24th 2019, 12:25:10

所以这些值是日期格式。

我感谢任何帮助

let endDateTime = moment
  .unix(parseInt(auctionEndDateTime))
  .format("MMMM Do YYYY, h:mm:ss");


let start=moment(Date.now());
let end=moment(endDateTime);
let duration = moment.duration(end.diff(start));
let hours = duration.asHours();


console.log('hours ' + hours);
console.log('days ' + duration.asDays());

 // you can get the difference between two days with javascript Date class let firstDate = new Date('Sun Nov 24 2019 17:28:33'); //new Date('2019-11-12'); let secondDate = new Date('Tue Nov 26 2019 17:28:33');//new Date('2019-11-20'); let milliSFirst = firstDate.getTime(); let milliSSecond = secondDate.getTime(); console.log("diff in days " + (milliSSecond - milliSFirst)/(1000 * 3600 * 24) )

 // take the dates as milliseconds and then you can do the calculations let start=moment(Date.now()); let end=moment(Date.now() + 1000 * 3600 * 24 ); let duration = moment.duration(end.diff(start)); let hours = duration.asHours(); console.log('hours ' + hours); console.log('days ' + duration.asDays());
