I've got an input using the datepicker tool from jQuery. what i am trying to do is that user has to select different date formats by which he can input the dates 1) daily 2) weekly 3) yearly
how can i select different format on change? the problem is that if one format is selected it is not changing to another
  if (data == "Daily")
                {
                    alert("abc");
                    $(".sysDateFields").datepicker();
                }
                else if (data == "Weekly")
                {
                }
                else if (data == "Monthly") 
                {
                    alert("abc1");
                    $(".sysDateFields").datepicker({
                        changeMonth: true,
                        changeYear: true,
                        showButtonPanel: true,
                        dateFormat: 'MM yy',
                        onClose: function (dateText, inst) {
                            var month = $("#ui-datepicker-div .ui-datepicker-month :selected").val();
                            var year = $("#ui-datepicker-div .ui-datepicker-year :selected").val();
                            $(this).datepicker('setDate', new Date(year, month, 1));
                        }
                    });
                }
