您可能会注意到我在此视图中有一个弹出表单。另外，我想将employeeCalendar div中的所有代码放在部分视图中。由于弹出窗口，我必须确保在我的控制器中将我的 Post 方法重定向到我的 Get 方法，以便当弹出数据输入完成并取消此视图的日期时，我不会从窗口收到不需要的重新发送消息。做这些重定向的问题是我得到一个看起来不愉快的整页回发。所以我宁愿通过 Ajax 从局部视图中刷新我的 claendar。那么我该怎么做呢？这是我的控制器

   [HttpGet]
    [Authorize(Roles = "Administrator, Trainer, ManagerAccounts, ManagerIT")]
    public ActionResult BulkTraining()
    {
        if (SessionObjects.Tlevm == null)
        {
            return this.View(new TrainingListEmployeesViewModel());
        }

        return this.View(new TrainingListEmployeesViewModel(
            SessionObjects.Tlevm.EmployeeList,
            SessionObjects.TrainingName,
            SessionObjects.TrainingDescription));
    }

    [HttpPost]
    [Authorize(Roles = "Administrator, Trainer, ManagerAccounts, ManagerIT")]
    public ActionResult BulkTraining([FromJson] IEnumerable<ClientEmployeeSelector> employees, string trainingName, string trainingDescription)
    {
        // Items stored in Session used when saving the training dates for the employee
        // via the popup window
        SessionObjects.TrainingName = trainingName.JsonTrim();
        SessionObjects.TrainingDescription = trainingDescription.JsonTrim();
        SessionObjects.EmployeeIdList = employees.Select(x => x.SearchTextId).ToList();
        SessionObjects.EmployeeNameList = SessionObjects.EmployeeIdList.Count > 0
                        ? Employee.GetNameList(SessionObjects.EmployeeIdList)
                        : string.Empty;
        SessionObjects.Tlevm = new TrainingListEmployeesViewModel(
            employees.ToList(),
            SessionObjects.TrainingName,
            SessionObjects.TrainingDescription);
        return this.RedirectToAction("BulkTraining");
    }
