在Jquery validation里验证通过后，自定义提交不同的action路径，适合一个窗口既可以作为添加对话框也可以作为编辑对话框

$("#myform").validate({
                debug: true, //调试模式取消submit的默认提交功能
                ignore: '#Password,#ConfirmPassword',
                focusInvalid: false,
                //---------------------------------------------------------------------------
                submitHandler: function () {   //表单提交句柄,为一回调函数   
                    var submitway = $("#submitbtn").text();
                    if (submitway == "编辑保存")
                        var geturl = "/membership/update";
                    else if (submitway == "添加保存")
                        var geturl = "/membership/add";
                    var options = {
                        type: "post",
                        url: geturl,
                        dataType: "json",
                        data: $("#myform").serialize(),
                        success:function (data) {
                            if (data.success) {
                                alert(data.messages);
                                $("#AddMembership").modal('hide');
                                window.parent.location.reload();
                            }
                            else
                                alert(data.messages);

                    };
                    $.ajax(options);
                    return false;
                },
