在asp.net mvc中的Ajax View上分页、排序、搜索

Question

我正在使用asp.net mvc 4 和EF 6 创建一个网站，在该网站上我需要一个填充表，用于在Ajax 的 PartialView 上进行分页、排序和过滤/搜索。到目前为止，分页、排序和搜索功能运行良好，但我无法将其用于 Ajax，其中表格只会更新而不是重新加载页面。这是我的代码，

控制器

public PartialViewResult Flats(string sortOrder, string currentFilter, string strSearch, int? page)
{
    ViewBag.currentSort = sortOrder;
    if (strSearch != null)
    {
        page = 1;
    }
    else
    {
        strSearch = currentFilter;
    }
    ViewBag.CurrentFilter = strSearch;

    ViewBag.TitleSort = String.IsNullOrEmpty(sortOrder) ? "title_desc" : "";
    var FlatsOrder = from f in rentdb.FlatInfoes select f;
    if (!String.IsNullOrEmpty(strSearch))
    {
        FlatsOrder = FlatsOrder.Where(s => s.address_area.Contains(strSearch));
    }
    switch (sortOrder)
    {
        case "title_desc":
            FlatsOrder = FlatsOrder.OrderByDescending(a => a.title);
            break;
        default:
            FlatsOrder = FlatsOrder.OrderBy(a => a.title);
            break;
    }
    int pageSize = 5;
    int pageNumber = (page ?? 1);
    return PartialView(FlatsOrder.ToPagedList(pageNumber, pageSize));
}

查看

<div id="divTable" class="span12" style="background-color: #fff;">
    <table class="table table-hover">
        <thead style="background-color: #cccccc;">
            <tr>
                <th class="text-center">
                    @Ajax.ActionLink("Title", "Flats", new { sortOrder = ViewBag.TitleSort, currentFilter = ViewBag.CurrentFilter }, new AjaxOptions() {
                                            HttpMethod = "GET",
                                            UpdateTargetId = "divTable",
                                            InsertionMode = InsertionMode.Replace
                                        })
                </th>
            </tr>
        </thead>
    </table>
</div>

每当我单击Title 链接进行排序时，整个页面都会重新加载然后排序。如何通过 ajax 和 partialview 更新表格？非常需要这个帮助。谢谢。

您必须制作一个包含 PartialView 的普通视图，如下所示

查看

@model YourModelClass

@* some thing which will not effected when the Ajax request is done *@
@Html.Partial("_TablePartialView", Model)

部分视图，在这种情况下应命名为“_TablePartialView”，并应存在于“视图”文件夹内的“共享”文件夹中。

@model YourModelClass

<div id="divTable" class="span12" style="background-color: #fff;">
  <table class="table table-hover">
    <thead style="background-color: #cccccc;">
        <tr>
            <th class="text-center">
                @Ajax.ActionLink("Title", "AjaxFlats", new { sortOrder = ViewBag.TitleSort, currentFilter = ViewBag.CurrentFilter }, new AjaxOptions() {
                                        HttpMethod = "GET",
                                        UpdateTargetId = "divTable",
                                        InsertionMode = InsertionMode.Replace
                                    })
            </th>
        </tr>
    </thead>
  </table>
</div>

控制器

private YourModelClass GetModel(string sortOrder, string currentFilter, string strSearch, int? page)
{
   ViewBag.currentSort = sortOrder;
   if (strSearch != null)
   {
      page = 1;
   }
   else
   {
      strSearch = currentFilter;
   }
   ViewBag.CurrentFilter = strSearch;

   ViewBag.TitleSort = String.IsNullOrEmpty(sortOrder) ? "title_desc" : "";
   var FlatsOrder = from f in rentdb.FlatInfoes select f;
   if (!String.IsNullOrEmpty(strSearch))
   {
       FlatsOrder = FlatsOrder.Where(s => s.address_area.Contains(strSearch));
   }
   switch (sortOrder)
   {
      case "title_desc":
         FlatsOrder = FlatsOrder.OrderByDescending(a => a.title);
         break;
       default:
         FlatsOrder = FlatsOrder.OrderBy(a => a.title);
         break;
   }
   int pageSize = 5;
   int pageNumber = (page ?? 1);
   return FlatsOrder.ToPagedList(pageNumber, pageSize);

}

public ActionResult Flats(string sortOrder, string currentFilter, string strSearch, int? page)
{
     return View(GetModel(sortOrder, currentFilter, strSearch, page);
}

public ActionResult AjaxFlats(string sortOrder, string currentFilter, string strSearch, int? page)
{
     return PartialView("_TablePartialView", GetModel(sortOrder, currentFilter, strSearch, page);
}
