          </li>


    </div>
    </form>
  <script src="js/jquery.validate.min.js" type="text/javascript"></script>
</body>
</html>

this is because form id is generated when you put in a master page. use the form id "aspnetForm" and it will work. example:

<script type="text/javascript">
    $(document).ready(function() {
        $("#aspnetForm").validate();
    });
</script>

and in the HTML it will look like this

<input type="text" id="name" class="required" />
