Javascript第二天和前一天的功能

Question

I am developing a daily calendar and need to traverse to the next and previous day. How would I write this in javascript? Will the following calculate correctly when going to the next / previous month? Like C#'s DateTime.Today.AddDays(1) will?

new Date(year, month, day + 1)

My concern is that if I execute this on March 31st, it will calculate March 32nd...which wouldn't work obviously.

If someone could provide a function to do both that would be great!

Thanks in advance!

Answer 1

var dateString = '30 Apr 2010'; // date string
var actualDate = new Date(dateString); // convert to actual date
var newDate = new Date(actualDate.getFullYear(), actualDate.getMonth(), actualDate.getDate()+1); // create new increased date

Answer 2

You don't need to worry. It won't.

date = new Date(2012, 2, 31 + 1);
console.log(date);
