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)

复制代码 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 })
