Javascript - > Date validation not happening when Imask is used

Dear All

Pls visit following link


the top most field i.e.

Arrest Date formated  Pls enter dd-mm-yyyy format

when I enter date 50-55-2222  (dd-mm-yyyy) format

the Javascript function chkDate()  displayes the the day, month and year  correctly but not validated

i avail Year, Month and Day as follow (even tried  parseInt)

  1.  var yr=parseInt(idate.substring(6,10));
  2.    var mm=parseInt(idate.substring(3,5));
  3.    var dd=parseInt(idate.substring(0,2));

When I try

  1. if (dd > 31 ) 
  2.    {
  3.     alert ("Day cannot be Greater than 31  ");
  4.     inpdate.focus();
  5.     return false;
  6.    }
Validation doesnot takes place

However without mast the validation is working fine

please help
