With javascript function "getFullYear()" can you write more characters in a input box as you have defined with "maxlength". Maybe there are other functions with this behavior. I have not tested it. Reproducible: Always Steps to Reproduce: For example my "false" HTML and Javascript code: <input type="text" name="yearbox" size="2" maxlength="2"> <script type="text/javascript" language="javascript"> var now = new Date(); var year = now.getFullYear(); document.myform.yearbox.value=year; </script> If I use FF3, in the year box are 4 digits, but I think there should be only 2 digits. If I use FF2, there are only 2 digits.
