因此，这里有管理员菜单列表，在这些菜单下有上载新闻。单击此特定菜单后，我将称其为局部视图，如下所示。

$("#body_data").load("/Admin/GetDailyNews", function () {
          $("#dailyNews").dataTable({
                    "lengthMenu": [[5, 10, 25, 50, -1], [5, 10, 25, 50, "All"]],
                    "columnDefs": [{ "targets": 3, "orderable": false }],
                    "pagingType": "full_numbers",
                    "oLanguage": { "sSearch": "" },
                    "deferRender": true
          });
}

我在AdminController中的PartialViewResult如下：

[HttpGet]
public PartialViewResult GetDailyNews()
{
     var context=new MyContext();
     List<AVmodel.NewsEventsViewModel> model = new List<AVmodel.NewsEventsViewModel>();
     List<news> news = (from n in context.news where n.stdate >= System.DateTime.Now orderby n.stdate descending select n).ToList();
     foreach (var NEWS in news)
     {
          model.Add(new AVmodel.NewsEventsViewModel()
          {
               EDate = NEWS.stdate,
               EDesc = NEWS.brief,
               EName = Convert.ToString(NEWS.name),
               NID = NEWS.nid
          });
     }
     return PartialView("_UploadNews", model);
}

我的_UploadNews.cshtml如下

@model IEnumerable<MCB.Models.BusinessObjects.AVmodel.NewsEventsViewModel>
<table id="dailyNews" cellspacing="0" width="100%" class="table table-condensed table-hover table-responsive table-bordered order-column">
     <thead>
           <tr>
               <th>Event Date</th>
               <th>Event Name</th>
               <th>Detailed News</th>
               <th class="disabled">Actions</th>
          </tr>
     </thead>
     <tbody>
          @foreach (var news in Model)
          {
               <tr data-row="row_@news.NID">
                   <td>@news.EDate.Date.ToShortDateString()</td>
                   <td>@Convert.ToString(news.EName)</td>
                   <td>@Convert.ToString(news.EDesc)</td>
                   <td><button class="btn btn-primary" data-target="#editAddNews" data-toggle="modal" onclick="javascript: EditNews(this);" data-info="data_@news.NID"><span class="fa fa-edit"></span> </button>&nbsp; <button class="btn btn-danger" onclick="javascript: DeleteNews(this);" data-info="data_@news.NID"><span class="fa fa-trash-o"></span></button></td>
               </tr>
          }
     </tbody>
</table>

所以到现在为止还不错。一切进展顺利，表格仅显示未来的新闻。现在，管理员可以选择从表格中获取整个新闻集，包括过去的日子。所以我在我的局部视图中保留了一个复选框，如下所示，它是一个
引导程序开关类型 ：

<input type="checkbox" name="fetchNews-checkbox" data-on-text="All News" data-off-text="Upcoming News" data-on-color="primary" data-off-color="default" data-label-width="100px" data-label-text="News details">

并且我onswitchchange为该特定复选框写了一个，如下所示：

$("[name='fetchNews-checkbox']").on('switchChange.bootstrapSwitch', function (event, state) {
     if (state) 
     {
           fetchNews('all');
     }
     else 
     {
           fetchNews('upcoming');
     }
});

我的fetchNews功能如下：

function fetchNews(context)
{
    if(context!="")
    {
        $("#dailyNews").dataTable({
            "sPaginationType": "full_numbers",
            "bProcessing": true,
            "bServerSide": true,
            "sAjaxSource": "/Admin/FetchNews"
        });
    }
}

当这个函数被调用时，我得到一个警告，上面写着

DataTables警告：表id = dailyNews-无法重新初始化DataTable。有关此错误的更多信息，请参见
http://datatables.net/tn/3

我访问了上述链接，但一无所知。谁能告诉我， 如何调用控制器json方法并将新闻列表呈现到此表中？
