[HttpPost]   

        public ActionResult Add(Maticsoft.Model.Project.ProjectMoneyPlan model)   

        {   

            model.Money = new Maticsoft.Model.Struct.DRMB(model.Money).ToDouble().ToString();   

            Maticsoft.BLL.User.LoginUser login = new Maticsoft.BLL.User.LoginUser();

                    return View("List");   

                }

            {

            }   

        }   

 

第二种弹框成功后不刷新界面：

[HttpPost]   

        public ActionResult Add(Maticsoft.Model.Project.ProjectMoneyPlan model)   

        {   

            model.Money = new Maticsoft.Model.Struct.DRMB(model.Money).ToDouble().ToString();   

            Maticsoft.BLL.User.LoginUser login = new Maticsoft.BLL.User.LoginUser();   

            model.Creater = login.Email;   

            try  

            {   

                if (bll.Exist("Pro_MoneyPlan", "where ProCode='" + model.ProCode + "' ", "ProCode") && bll.Exist("Pro_MoneyPlan", "where Year=" + model.Year , "Year") && bll.Exist("Pro_MoneyPlan", "where Month=" + model.Month, "Month"))   

                {   

                   ViewData["ProName"] = SelecOpption.GetOpption("PRO_B", "", "Code,Name");//获取项目名称   

                   ViewData["Year"] = GetYear();   

                   ViewData["Month"] = GetMonth();   

                   ///弹框   

                   ViewBag.isExist = false;   

                   return View();   

                }   

                else  

                {   

                    bll.Add(model);   

                    return View("List");   

                }   

            }   

            catch (Exception ex)   

            {   

                return new Maticsoft.BLL.Error().DoError(ex);   

            }   

        }   

前台：

@if (ViewBag.isExist == false)   

{   

    <script type="text/javascript">   

        alert("您要添加的数据已经存在！")   

    </script>   

}
