Dual format date validation needed

[Tarkon]

Hi,

I'm looking for a script that will validate a date in at least two formats. Specifically, US (mm/dd/yyyy), and a custom format (yyyy/mm/dd). I'm already stripping out invalid characters, but I need to make sure that the date is in one of the proper formats, and that the day is correct.

I've tried taking existing scripts and combining them and changing around the formats, but I obviously don't know enough about Javascript to make it work.

Any help would be very much appreciated.

Thanks!

I looked at this site and I'm not sure it's what I'm looking for - I don't see how I can validate a date based upon the format I need, plus installing all of the functions it has available just for this one little instance seems like overkill.

Nice site, though

try this:

function isValidDate(sDate, iFormat){ //iFormat: 0 = mm/dd/yyyy, 1 = yyyy/mm/dd
   var bValid = true;
   var arr = sDate.split('/');
   var d;

   switch (iFormat){
     case 0:
       d = new Date(arr[2],arr[0]-1,arr[1]);
       if (d.getDate()!=arr[1] || d.getMonth()!=arr[0]-1 || d.getFullYear()!=arr[2]) bValid=false;
       break;
     case 1:
       d = new Date(arr[0],arr[1]-1,arr[2]);
       if (d.getDate()!=arr[2] || d.getMonth()!=arr[1]-1 || d.getFullYear()!=arr[0]) bValid=false;
       break;
     default:
       bValid=false;
   }
   return bValid;
}
