How to properly add 1 month from now to current date in moment.js
提问by Hyman Moscovi
I read the documentation of moment.js that if you want to add 1 month from the current date time you use this code
我阅读了 moment.js 的文档，如果您想从当前日期时间添加 1 个月，请使用此代码
var moment = require('moment');
var futureMonth = moment().add(1, 'M').format('DD-MM-YYYY');
But the problem right now, it is not properly add the date correctly, for example let say the current date is 31/10/2015, explain in code
但是现在的问题，不是正确添加日期，例如假设当前日期是 31/10/2015，在代码中解释
var currentDate = moment().format('DD-MM-YYYY');
var futureMonth = moment().add(1, 'M').format('DD-MM-YYYY');
console.log(currentDate) // Will result --> 31/10/2015
console.log(futureMonth) // Will result --> 30/11/2015
if you take a look at the current calendar time, 1 month from 31/10/2015supposed to be 1/12/2015
如果您查看当前的日历时间，31/10/2015应该是1 个月后1/12/2015
Could anyone give me some opinion on how to fix this problem.
谁能给我一些关于如何解决这个问题的意见。

var currentDate = moment('2015-10-30');
var futureMonth = moment(currentDate).add(1, 'M');
var futureMonthEnd = moment(futureMonth).endOf('month');
if(currentDate.date() != futureMonth.date() && futureMonth.isSame(futureMonthEnd.format('YYYY-MM-DD'))) {
futureMonth = futureMonth.add(1, 'd');
}
console.log(currentDate);
console.log(futureMonth);
EDIT
编辑
moment.addRealMonth = function addRealMonth(d) {
var fm = moment(d).add(1, 'M');
var fmEnd = moment(fm).endOf('month');
return d.date() != fm.date() && fm.isSame(fmEnd.format('YYYY-MM-DD')) ? fm.add(1, 'd') : fm;
}
var nextMonth = moment.addRealMonth(moment());

You could try
你可以试试
moment().add(1, 'M').subtract(1, 'day').format('DD-MM-YYYY')

startdate = "20.03.2020";
var new_date = moment(startdate, "DD-MM-YYYY").add(5,'days');
alert(new_date)
