Question

我试图清除表单控制器并使用ModelState.Clear（）;但是不行。我希望在将表单保存到数据库后清除表单。是否有可能刷新视图并清除表单jquery。

 <td>
                    @Ajax.ActionLink("Show Post Order", "_ListPost", new { idOrder = @item.IdOrder }, new AjaxOptions()
               {
                   HttpMethod = "GET",
                   LoadingElementId = "divLoading",
                   UpdateTargetId = "divPosition",
                   InsertionMode = InsertionMode.Replace

               }, new { @class = "btn btn-primary" })
                </td>
                <td>


                    @Ajax.ActionLink("Add Answer", "_AddPost", new { idZlecenia = @item.IdZlecenia }, new AjaxOptions()
               {
                   HttpMethod = "GET",
                   LoadingElementId = "divLoadingForm",
                   UpdateTargetId = "divAddPozycje",
                   InsertionMode = InsertionMode.Replace

               }, new { @class = "btn btn-primary" })
                </td>

            </tr>
            ...
            <tr id="divAddPozycje"></tr>
        }

[HttpPost]
        [ValidateAntiForgeryToken]
        public PartialViewResult _AddPost(int idOrder, AddPositionViewModel viewModel)
        {
            var findOrder = db.Order.Find(idOrder);

            if (ModelState.IsValid)
            {

                OrderPosition position = new OrderPosition { Description = viewModel.Description };
                db.OrderPosition.Add(position);
                findOrder.OrderPositionList.Add(position);
                db.SaveChanges();
                ViewBag.Information = position;                  
            }
            Thread.Sleep(2000);
            ModelState.Clear();
            return PartialView();              
        }

并查看_AddPost - Paritial View。这个partialView添加位置命令。使用不添加项目的Html Ajax添加项目页面刷新

@model AplikacjaHelpDesk.ViewModels.AddPositionViewModel

@{
    ViewBag.Title = "Add Post";
    Layout = null;
}

<link href="~/Content/font-awesome.min.css" rel="stylesheet" />
<script src="~/Scripts/tinymce/tinymce.min.js"></script>
<script src="~/Scripts/bootstrap.min.js"></script>
<script src="~/Scripts/jquery-2.2.3.min.js"></script>   
<div class="container-fluid">
    @using (Ajax.BeginForm(new AjaxOptions()
    {
        UpdateTargetId = "divformResult",
        HttpMethod = "Post"

    }))    
    {
        @Html.AntiForgeryToken()
        @Html.Hidden("IdOrder")
        <div class="form-horizontal">
            @Html.ValidationSummary(true, "", new { @class = "text-danger" })
            <div class="form-group">
                @Html.LabelFor(model => model.Description, htmlAttributes: new { @class = "control-label col-md-1" })
                <div class="col-md-10">
                    @Html.TextAreaFor(model => model.Description, new { htmlAttributes = new { @class = "form-control" } })
                    @Html.ValidationMessageFor(model => model.Description, "", new { @class = "text-danger" })
                </div>
            </div>   
            <div class="form-group">
                <div class="col-md-offset-2 col-md-10 ">
                    <input type="submit" value="Save" class="btn btn-danger" />
                </div>
            </div>
        </div>
    }        
</div>
