In my form, I have three select elements, which are Month, Day, and Year. What I'm achieving is, if the user selects a month, the days must match according to what month the user has selected.
For example, January(1-31), May(1-30), February(1-28).

function GetDays(year, month) {
var isLeapYear = ((year % 4 === 0 && year % 100 !== 0) || year % 400 === 0);
return [31, (isLeapYear ? 29 : 28), 31, 30, 31, 30, 31, 31, 30, 31, 30, 31][month];
}
Call GetDays function on change event of month selection control

Where should I put the `GetDays` function? Inside the `month` selection? – darkAnonymous Dec 20 '15 at 08:48

` function DDLMonth_Change(control){ var totalDays = GetDays(2015,10); //fill days dropdown }` – Bhavik Jani Dec 21 '15 at 05:33
