Now you want only for Integer no decimals

function IsNumeric(strString)
   //  check for valid numeric strings      
   var strValidChars = "0123456789";
   var strChar;
   var blnResult = true;

   if (strString.length == 0) return false;

   //  test strString consists of valid characters listed above
   for (i = 0; i < strString.length && blnResult == true; i++)
      strChar = strString.charAt(i);
      if (strValidChars.indexOf(strChar) == -1)
         blnResult = false;
   return blnResult;

function isNumeric(string)
   if ( parseInt(string) != null && parseInt(string) != undefined )
     return true;
     return false;
