时刻查找两个日期对象之间的差异

发布于 2025-01-19 07:26:12 字数 592 浏览 0 评论 0原文

我的项目中有两个日期，

let a="30-03-1999"
let b="30-03-2022"

现在我需要找到这两个日期之间的差异，所以首先我通过

let birthdate = moment(a, 'DD-MM-YYYY')
let licenseDate = moment(b, 'DD-MM-YYYY')

//console.log(birthdate,licenseDate) gives me moment object 

Object { _isAMomentObject: true, _i: "30-03-1950", _f: "DD-MM-YYYY", _isUTC: false, _pf: {…}, _locale: {…}, _d: Date Thu Mar 30 1950 00:00:00 GMT+0530 (India Standard Time), _isValid: true }

函数将它们转换为 moment 对象

var diff = licenseDate.diff(birthdate, 'years')

运行返回 NaN 的

Now i need to find the difference between these two dates, so first i am converting them to moment object by

let birthdate = moment(a, 'DD-MM-YYYY')
let licenseDate = moment(b, 'DD-MM-YYYY')

//console.log(birthdate,licenseDate) gives me moment object 

Object { _isAMomentObject: true, _i: "30-03-1950", _f: "DD-MM-YYYY", _isUTC: false, _pf: {…}, _locale: {…}, _d: Date Thu Mar 30 1950 00:00:00 GMT+0530 (India Standard Time), _isValid: true }

upon running the function

var diff = licenseDate.diff(birthdate, 'years')

it returns NaN

DD-MM-YYYY 不是正确的日期格式，您应该尝试使用 YYYY-MM-DD，它会正常工作

let a="1999-03-30"
let b="2022-03-30"
var date1 = moment(a);
var date2 = moment(b);
console.log(date1.diff(date2, 'years'))

，并且也可以使用 DD- MM-YYYY

let a="30-03-1999"
let b="30-03-2022"
var date1 = moment(a, 'DD-MM-YYYY');
var date2 = moment(b, 'DD-MM-YYYY');
console.log(date1.diff(date2, 'days'))

DD-MM-YYYY is not the correct date format, you should try with YYYY-MM-DD, It will work fine

let a="1999-03-30"
let b="2022-03-30"
var date1 = moment(a);
var date2 = moment(b);
console.log(date1.diff(date2, 'years'))

and It will also with DD-MM-YYYY

let a="30-03-1999"
let b="30-03-2022"
var date1 = moment(a, 'DD-MM-YYYY');
var date2 = moment(b, 'DD-MM-YYYY');
console.log(date1.diff(date2, 'days'))
