jQuery AJAX call with validation:

        // Specify the validation rules
        rules : {

                alphanumericsd : true
            },

        },

        submitHandler : function(form) {

                var departmentname = $('#departmentname').val();
                $.ajax({
                    url : $("#add-new-department").attr("action"),
                    type : "POST",
                    data : "departmentname="+departmentname,

                    success : function(response) {
                        if($.isEmptyObject(response)) { 
                            $('#department_status').html('Sorry! Duplicate Record!').css('color','red').show().fadeOut(5000);

                            $('#departmentname').val('');
                            $('#department').append(new Option(response.departmentname,response.departmentid));
                        }

                    },  
                 error : function(e) {  
                  alert('Error: ' + e.responseText);

        submitHandler : function(form) {

                        $('#typeofvehicle').append(new Option(response.vehicletype,response.vehicleid));
                        }
                    },  
                 error : function(e) {  
                  alert('Error: ' + e);   
                 } 
                });
        }
    });

I want to minimize my code because I have so many add new options in my project.

So, please suggest ways to write only single code for modal dialog and one jQuery AJAX call as more general.
