Compare entered date with current date

Hello all,

I am entering date from a calender in a textbox named "date" in the formate of (yyyy-mm-dd) like (2010-01-02).

I want to compare the entered date with todays current date ,
so that past date can not be submitted in the textbox.

i am using the code below to get todays current date to compare with text box value :-

var currentTime = new Date();
var Cmonth = currentTime.getMonth() + 1 ;
var Cday = currentTime.getDate();
var Cyear = currentTime.getFullYear();
var Today = (Cyear + "-" + Cmonth + "-" + Cday);
alert(Today);

Code (markup):

But it gives todays date in the form of (2009-1-2)
rather than (2009-01-02).

please suggest me how this date can be achieved like (2009-01-02).

Please also suggest how the entered date can be compared with the achieved Todays current date ,
so that past date cannot be submitted.


Thanks & Regards.

 

Hello,

To achieve the zeroes in front of the code you can simply check if the day/month is smaller than ten, if yes, add a 0. Example:

var currentTime = new Date();
var Cmonth = currentTime.getMonth() + 1 ;
var Cday = currentTime.getDate();
var Cyear = currentTime.getFullYear();
Cday = (Cday < 10) ? '0' + Cday : Cday;
Cmonth = (Cmonth < 10) ? '0' + Cmonth : Cmonth;
var Today = (Cyear + "-" + Cmonth + "-" + Cday);
alert(Today);

To compare dates I suggest you check the w3 schools page on it: http://www.w3schools.com/jS/js_obj_date.asp
