Adding dates in JavaScript in one line

Question

I'm trying to manipulate dates using JavaScript on a single line, and I'm having problems with the year (not the month or day). I got this idea from the link . Did I miss something?

The code is as follows:

var newyear = new Date((new Date()).getYear(), (new Date()).getMonth(), (new Date()).getDate()+5).getFullYear();
document.write(newyear);

This gives me "110".

I'm not sure why? Thank!

Answer 1

(new Date()).getYear()

Here you have to use getFullYear(). getYear()in JS funds (year and minus 1900) .

Answer 2

var newyear = new Date((new Date()).getFullYear(), (new Date()).getMonth(), (new Date()).getDate()+5).getFullYear();

Answer 3

Y2K , :

var newyear = new Date(new Date().setDate(new Date().getDate()+5)).getFullYear()

Date , Date , , .

var d = new Date(); d.setDate(d.getDate()+5); var newyear = d.getFullYear()
