MVC简易分页(Razor)

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)

    @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 })
