This is a very complex matter if you are going to do it securely.... Perhaps you should purchase a 3rd party tool.

Actually I want to allow only number in a textbox not alphabets. The code which I have posted is accepting both and also special symbols. I can just see on the status bar that error in script.

Please help me in doing this...

I just ran the script you have me on FireFox 2.0 and IE7 and it works absolutely fine. You must have Javascrip enabled because of the error.... I ave not idea what the problem could be....

You are using evt and event. The evt object is null in IE6. Try this:

function isNumberKey(evt)
      {
         if(!evt) evt = event;  
         var charCode = (evt.which) ? evt.which : evt.keyCode
         if (charCode > 31 && (charCode < 48 || charCode > 57))
            return false;

         return true;
      }
