这一刻没有给我两次约会的时间差异

Question

我有这样一个代码，我有我的日期和当前/今天的日期，我需要在两个日期之间的天差。我总是得到0或一些大数字“31536000000”，什么错了？

const startDate = moment(job.published_date, 'YYYY-MM-DD').format('YYYY,MM,DD')  //looks like this "2018,08,19"
const endDate = moment(new Date()).format('YYYY,MM,DD') //looks like this "2019,09,12"
const a = moment([ startDate, ])   
const b = moment([ endDate, ])
console.log('DIFFERENCE IN DAYS', b.diff(a))

Answer 1

dayCount(startDate,endDate){
  const startDateMoment = moment(startDate, 'YYYY-MM-DD').unix();
  const endDateMoment = moment(endDate,"YYYY-MM-DD").unix();

  const dayCount = (endDateMoment-startDateMoment)/86400;

  //or 
  //const diff = endDateMoment-startDateMoment;
  //const dayCount = moment.duration(diff,'s').asDays()

  return dayCount
}

render() {
  let dayCount= this.dayCount("2018,08,19","2019,09,12");
  console.log(dayCount)
}
