how select date from CalendarControl.js in reverse order
<p>I have CalendarControl.js, which on selecting date gives me date in format 14-Aug-2012.But I want To select date from that as 2012-08-14 so as use in MySQL query as it display records for date on inserting in 2012-08-14 format./*here I change it as
     var months = ['01','02','03','04','05','06','07','08','09','10','11','12'];
    then I am getting month as number but want to reverse it. </p>
