Event binding

@@adsense
Many widgets have any events. Metro UI CSS provides several ways to define events.
Function name

                <form data-role="validator" data-on-submit="func_name">
                    ...
                </form>

                <script>
                    function func_name(form){
                        return false;
                    }
                </script>
Internal javascript

                <form data-role="validator" data-on-submit="return false">
                    ...
                </form>
Javascript

                <form id="form1">
                    ...
                </form>

                <script>
                    $(function(){
                        $("#form1").validator({
                            onSubmit: function(form){
                                return false;
                            }
                        });
                    });
                </script>
