MVC 弹出提示框

第一种弹框成功后要刷新界面

[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"))
{
///弹框
string script = String.Format("<script>alert('数据已经存在!');location.href='{0}'</script>", Url.Action("Add"));
return Content(script ,"Text/html");
}
else
{
bll.Add(model);
return View("List");
}
}
catch (Exception ex)
{
return new Maticsoft.BLL.Error().DoError(ex);
}
}

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>
}
