javascript - 时刻没有给我两个日期之间的天数差异

Question

我有一个这样的代码，其中有我的日期和当前/今天的日期，我需要获得两个日期之间的天数差异。我总是得到 0 或某个大数字“31536000000”出了什么问题？

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

const startDate = moment('2017-08-16', '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', moment.duration(b.diff(a)).asDays());
// DIFFERENCE IN DAYS 730

您需要从差异发生后的那一刻起获取持续时间值 - 然后将其格式化为天。
