我目前使用 PagedList 库(https://github.com/TroyGoode/PagedList)在我的 MVC 3 项目中进行分页。
我想将此代码转换为使用 ajax 使用新结果更新页面,而不是刷新整个页面。我真的不知道该怎么做。我对来自 Webforms 的 MVC 相当陌生。任何帮助将不胜感激!
这是我的代码:
家庭控制器:
//#####################################
// ActionResult = Retrieve Comments
//#####################################
[ChildActionOnly]
public ActionResult _Comments(int ProductID, int? Page)
{
//Perform the Database Query.
try
{
//SQL Query - Get * records
var Model = from r in DB.Comments where r.ProductID == ProductID select r;
//Page number passed in via url. Default to 1 if not specified.
var PageNumber = Page ?? 1;
//Grab 6 results from the result set.
var Results = Model.ToPagedList(PageNumber, 6);
//Store Paged Result set in ViewBag for Paging.
ViewBag.Results = Results;
//Store in ViewBag for display (Page 1 of 43)
ViewBag.PageNumber = PageNumber;
//Get Total Pages: Divide Total Records by 6 Records per page.
ViewBag.PageCount = Model.Count() / 6 + 1;
//Return Records to my view.
return PartialView(Results);
}
//There was an error.
catch
{
//ViewBag.ErrorMessage = ex;
return PartialView("Error");
}
}
部分视图:_评论
@model IEnumerable<DH.Models.Comment>
@using PagedList.Mvc;
@using PagedList;
@{
//No Comments Yet
if (@Model.Count() == 0)
{
<div id="CommentStatus">Be the first to comment on this product!</div>
}
//There are comments!
else
{
foreach (var item in Model)
{
//html for writing out the comments...
}
}
}
<div>Page @ViewBag.PageNumber of @ViewBag.PageCount</div>
@Html.PagedListPager((IPagedList)ViewBag.Results, Page => Url.Action("Index", new { Page = Page }), new PagedListRenderOptions { LinkToPreviousPageFormat = "< Prev", LinkToNextPageFormat = "Next >", LinkToLastPageFormat = "Última >>" })
模型
namespace DH.Models
{
public class Comment
{
public int CommentID { get; set; }
public int ProductID { get; set; }
public string Author { get; set; }
public string Message { get; set; }
public DateTime MessageDate { get; set; }
public int ThumbsUp { get; set; }
public int ThumbsDown { get; set; }
public string IP { get; set; }
}
}
