MVC 4 在部分视图中使用分页列表

Question

我正在尝试在局部视图中实现 PagedList。

描述视图设置。我有 Controller A with ViewA。这是父视图并有自己的模型。然后我有 Controller B with PartialViewB 并且也有自己的模型。然后我在 ViewA 中有一个 Div 将用于显示 PartialViewB。我可以在按下按钮后加载 PartialViewB，然后再次按下按钮后隐藏视图。 PartialViewB 中是 PagedList。点击下一页按钮加载下一页，但将其加载到自己的页面中，而不是像以前那样在 ViewA 中加载。

我可以根据需要加载更多代码，但现在这里是寻呼机

<br />
    Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of @Model.PageCount

    @Html.PagedListPager(Model, page => Url.Action("ViewComments",
    new { courseID = @ViewBag.courseID, page }), 
    new PagedListRenderOptions { MaximumPageNumbersToDisplay = 5, DisplayLinkToFirstPage = PagedListDisplayMode.IfNeeded, 
        DisplayLinkToLastPage = PagedListDisplayMode.IfNeeded })

::编辑::

父视图

<div class="Comments">
    <input type="button" id="View" class="CommentsButton" value="View Comments"/>
    <input type="hidden" id="Hidden" value="false" />
</div>
<div id="Comments">
</div>

局部视图

@model PagedList.IPagedList<QIEducationWebApp.Models.CourseComment>
@using PagedList.Mvc;

@{
    ViewBag.Title = "Comments";
}

<h2>Comments!</h2>

<table>

@foreach (var item in Model)
{
    <tr>
        <td>
            @Html.DisplayFor(modelItem => item.CommentDate)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.UserName)
        </td>
        <td>
            @Html.DisplayFor(modelItem => item.CommentText)
        </td>
    </tr>
}

</table>

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")" type="text/javascript"></script>

<appSettings>
  <add key="UnobtrusiveJavaScriptEnabled" value="true"/> 
</appSettings>

<br />
    Page @(Model.PageCount < Model.PageNumber ? 0 : Model.PageNumber) of @Model.PageCount

    @Html.PagedListPager(Model, page => Url.Action("ViewComments",
    new { courseID = @ViewBag.courseID, page }),
            PagedListRenderOptions.EnableUnobtrusiveAjaxReplacing(
                new PagedListRenderOptions { MaximumPageNumbersToDisplay = 5, DisplayLinkToFirstPage = PagedListDisplayMode.IfNeeded, 
                DisplayLinkToLastPage = PagedListDisplayMode.IfNeeded },
                new AjaxOptions() { HttpMethod = "GET", UpdateTargetId = "Comments" }))

BundleConfig.cs

public class BundleConfig
    {

            // Use the development version of Modernizr to develop with and learn from. Then, when you're
            // ready for production, use the build tool at http://modernizr.com to pick only the tests you need.
            bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                        "~/Scripts/modernizr-*"));

            bundles.Add(new StyleBundle("~/Content/css").Include("~/Content/site.css", "~/Content/PagedList.css"));

            bundles.Add(new StyleBundle("~/Content/themes/base/css").Include(

看看这个：Related SO question

这将使用不显眼的 ajax 为您进行替换。您只需要处理提取并在您的末端跳过并将新的局部视图与模型一起发回。

@Html.PagedListPager(Model, page => Url.Action("ViewComments", page }), PagedListRenderOptions.EnableUnobtrusiveAjaxReplacing( new AjaxOptions(){  HttpMethod = "GET", UpdateTargetId = "partialContainerYouNeedToReplace"}))

确保在执行此操作时在页面上引用了不显眼的 js。它带有开箱即用的 MVC，您应该只需要引用该包。

希望对您有所帮助。
