ASP.NET MVC4 Razor模板简易分页效果

一、无数据提交

第一步，建立一个 Controller命名为PageIndex的空控制器,自定义一个方法如下:   

 public ActionResult PageIndex(string action, string controller, int currentPage, int pageCount)
 {
 //int count = db.Product.Count();
 ViewBag.PageCount = pageCount;//从操作中获取总数据页数将传入分页视图页面
 ViewBag.CurrentPage = currentPage;//从操作中获取当前页数将传入分页视图页面
 ViewBag.action = action;
 ViewBag.controller = controller;
 return PartialView();
 }

传入四个参数： 

action：操作（要分页的视图的操作，默认为Index）；

controller：控制器；

currentPage：当前页数；

pageCount：数据总页数

第二步：添加视图（PageIndex）

@if (ViewBag.PageCount == null || ViewBag.PageCount == 0)
　　　　{
 　　　　<span>您好，当前没有数据显示!</span>
　　　　}
　　　　else
　　　　{
 　　　　if (ViewBag.CurrentPage <= 10)
 　　{
 　　<span><a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = 1 }, null)">
 首页</a>|</span>
 　　}

 else
 {
 <a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = 1 }, null)">
 首页</a>

 <span><a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = ViewBag.CurrentPage - 10 }, null)">
 ...</a> </span>
 
 }
 for (int i = ViewBag.CurrentPage - 3; i < ViewBag.CurrentPage + 3; i++)
 {
 if (i <= 0)
 {
 continue;
 }
 if (i > ViewBag.PageCount)
 {
 break;
 }
 <span><a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = i }, null)">
 第 @i 页</a>|</span>
 }
 if (ViewBag.CurrentPage > 1)
 {
 <span><a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = ViewBag.CurrentPage - 1 }, null)">
 上一页</a>|</span>
 }
 if (ViewBag.PageCount > ViewBag.CurrentPage)
 {
 <span><a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = ViewBag.CurrentPage + 1 }, null)">
 下一页</a></span>
 }
 if (ViewBag.CurrentPage == ViewBag.PageCount || ViewBag.CurrentPage >= ViewBag.PageCount - 10)
 {
 
 <a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = ViewBag.PageCount }, null)">
 尾 页</a>
 }
 else
 {
 <span><a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = ViewBag.CurrentPage + 10 }, null)">
 ...</a></span>
 <a href="@Url.Action(ViewBag.action, ViewBag.controller, new { PageIndex = ViewBag.PageCount }, null)">
 尾 页</a>
 }
 <span style="padding-left: 20px">当前页数： @ViewBag.CurrentPage | 共 @ViewBag.PageCount 页
 </span>
　　　　}

第三步：操作的视图的控制器修改

public ViewResult Index(int? pageIndex)
　　　　{
　　　　　　int pageInd = pageIndex.HasValue ? pageIndex.Value : 1;
 　　　　　 ViewBag.PageCount = (int)Math.Ceiling(result.Count() / 20.0);

　　　　　　//这里的是take，按照每页20个显示
　　　　　　return View(result.OrderBy(t => t.PID).Skip((pageInd - 1) * 20).Take(20));
　　　　}

第四步：页面调用（即最后一步）

代码如下:@Html.Action("PageIndex", "Product", new { action = "Index", controller = "Log", pageCount = ViewBag.PageCount, currentPage = ViewBag.CurrentPage })

一般来说，数据都是变动的。 

二、有数据提交

 第一步：建立一个 Controller命名为PageIndex的空控制器,自定义一个方法如下: 

 public ActionResult PageIndexKey(int currentPage, int pageCount)
 {
 ViewBag.PageCount = pageCount;//从操作中获取总数据页数将传入分页视图页面
 ViewBag.CurrentPage = currentPage;//从操作中获取当前页数将传入分页视图页面
 return PartialView();
 }

第二步：建立分布视图

 <script>
 $(function () {
 $("#pageingByForm a").click(function (event) {
 $("#pageIndex").val($(this).attr("pageIndex"));
 //$(this).parent("Form").submit();
 document.getElementsByTagName("Form").item(0).submit();
 event.preventDefault();
 });
 });
</script>
@Html.Hidden("pageIndex")
<div id="pageingByForm">
 @if (ViewBag.PageCount == null || ViewBag.PageCount == 0)
 {
 <span>当前没有数据</span>
 }
 else
 {
 if (ViewBag.CurrentPage <= 10)
 {
 <span><a pageindex="1" href="#">首页</a>|</span>
 }

 else
 {
 <span><a pageindex="1" href="#">首页</a>|</span>

 <span><a pageIndex="@(ViewBag.CurrentPage - 10)" href="#">...</a>|</span>
 }
 for (int i = ViewBag.CurrentPage - 3; i < ViewBag.CurrentPage + 3; i++)
 {
 if (i <= 0)
 {
 continue;
 }
 if (i > ViewBag.PageCount)
 {
 break;
 }
 <span><a pageIndex="@i" href="#">第 @i 页</a>|</span>
 }
 if (ViewBag.CurrentPage >1)
 {
 <span><a pageIndex="@(ViewBag.CurrentPage - 1)" href="#">上一页</a>|</span>
 }
 if (ViewBag.PageCount > ViewBag.CurrentPage)
 {
 <span><a pageIndex="@(ViewBag.CurrentPage + 1)" href="#">下一页</a></span>
 }
 if (ViewBag.CurrentPage >= ViewBag.PageCount - 10)
 {
 }
 else
 {
 <span><a pageIndex="@(ViewBag.CurrentPage + 10)" href="#">...</a>|</span>
 <span><a pageIndex="@ViewBag.PageCount" href="#">尾 页</a></span>
 }
 <span style="padding-left: 20px">当前页数： @ViewBag.CurrentPage | 共 @ViewBag.PageCount 页
 </span>
 }
</div>

第三步：修改操作视图和控制器

public ViewResult Index(int? pageIndex ,string search)
　　{
　　int pageInd = pageIndex.HasValue ? pageIndex.Value : 1;
 　　ViewBag.PageCount = (int)Math.Ceiling(result.Count() / 20.0); 
　　return View(result.OrderBy(t => t.PID).Skip((pageInd - 1) * 20).Take(20));
　　}

视图（页面调用）：
 @using (Html.BeginForm())
{ 

根据性别得到查询结果 

性别: @Html.TextBox("sex")

<input type="submit" value="查询" />  

@Html.Action("PageIndexKey", "PageIndex", new { pageCount = ViewBag.PageCount, currentPage = ViewBag.CurrentPage })
 
} 

Example： 

　　　　//数据,一个list的集合 
　　　　List<string> s = new List<string>(); 
 s.Add("张军"); 
 ViewBag.PageCount = (int)Math.Ceiling(s.Count() / 20.0); 
 return View(s.Skip((pageInd - 1) * 20).Take(20)); 
　　　　@Html.Action("PageIndex", "PageIndex", 
　　　　new { action = "", controller = "", pageCount = ViewBag.PageCount, currentPage = ViewBag.CurrentPage })
