<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script> <script> $('.puankontrol').change(function() { var x = $(this).val() * 1; if((x < 1) || (x > 5)) { $(this).val(3); alert("Please enter value between 1-5!"); } }); </script> </head> <body> <form> <input class="puankontrol" type="text" name="puan"/><BR> <input class="puankontrol" type="text" name="puan"/><BR> <input class="puankontrol" type="text" name="puan"/><BR> </form> <div id="other"> Trigger the handler </div> </body> </html>
