      // Loop through and check for these numbers
      var numbers=new Array("1","2","3","4","5","6","7","8","9","0");
      str=str.toString();
      var isbad1=true;
      var sendback;
      sendback="";
      // loop through the string that was sent to this function      
      for(i=0; i<str.length; i++)
           {
           // test each element of the string against the array of numbers
            for(j=0; j<numbers.length; j++)
                {
                // if we found a match, add to temp string to return back
                  if( str.substring(i,i+1)==numbers[j] )
                    {
                     j = numbers.length;
                     sendback = sendback + str.substring(i,i+1);
                    }
            }

parseInt will give you back digits as long as it can.  In your case, you
would get 11 for the parseInt value which is a number so isNaN is false.

ml/js56jsmthparseint.asp

The example from this reference is as follows:

parseInt("12abc")   // Returns 12.
