  • 一个asp.net MVC 的分页代码

    哈哈,这个博客的处女文啦~~

    首先声明,这个分页代码并不是出自我手哈,借用了网上的一段代码,然后加了个css,变的好看一些啦~~

    原作者忘记是谁了,实在找不到了……万分抱歉啊~~

    效果如下:

    1 using System;
    2  using System.Collections.Generic;
    3  using System.Linq;
    4  using System.Web;
    5  using System.Web.Mvc;
    6  using System.Web.Routing;
    7  using System.Text;
    8  using System.Web.Mvc.Html;
    9  namespace application.Helpers
    10 {
    11 public static class PagerExtensions
    12 {
    13 /*helper分页
    14 *使用方式:<%@ Import Namespace="ExpoShiep.Helpers" %>
    15 *<%=Html.Pager("page",10,100)%>*/
    16 /// < summary>
    17 /// 分页Pager显示
    18 /// < /summary>
    19 /// < param name="html">< /param>
    20 /// < param name="currentPageStr">标识当前页码的QueryStringKey< /param>
    21 /// < param name="pageSize">每页显示< /param>
    22 /// < param name="totalCount">总数据量< /param>
    23 /// < returns>< /returns>
    24   public static string Pager(this HtmlHelper html, string currentPageStr, int pageSize, int totalCount)
    25 {
    26 var queryString = html.ViewContext.HttpContext.Request.QueryString;
    27 int currentPage = 1; //当前页
    28   var totalPages = Math.Max((totalCount + pageSize - 1) / pageSize, 1); //总页数
    29   var dict = new System.Web.Routing.RouteValueDictionary(html.ViewContext.RouteData.Values);
    30 var output = new System.Text.StringBuilder();
    31 if (!string.IsNullOrEmpty(queryString[currentPageStr]))
    32 {//与相应的QueryString绑定
    33 foreach (string key in queryString.Keys)
    34 if (queryString[key] != null && !string.IsNullOrEmpty(key))
    35 dict[key] = queryString[key];
    36 int.TryParse(queryString[currentPageStr], out currentPage);
    37 }
    38 else
    39 {//获取 ~/Page/{page number} 的页号参数
    40 int.TryParse(dict[currentPageStr].ToString(), out currentPage);
    41 }
    42 if (currentPage <= 0)
    43 currentPage = 1;
    44 if (totalPages > 1)
    45 {
    46 if (currentPage != 1)
    47 {//处理首页连接
    48 dict[currentPageStr] = 1;
    49 output.AppendFormat("{0} ", html.RouteLink("首页", dict));
    50 }
    51 if (currentPage > 1)
    52 {//处理上一页的连接
    53 dict[currentPageStr] = currentPage - 1;
    54 output.Append(html.RouteLink("上一页", dict));
    55 }
    56 else
    57 {
    58 //output.Append("上一页");
    59 dict[currentPageStr] = currentPage;
    60 output.Append(html.RouteLink("上一页", dict));
    61 }
    62 output.Append(" ");
    63 int currint = 5;
    64 for (int i = 0; i <= 10; i++)
    65 {//一共最多显示10个页码,前面5个,后面5个
    66 if ((currentPage + i - currint) >= 1 && (currentPage + i - currint) <= totalPages)
    67 if (currint == i)
    68 {//当前页处理
    69 //output.Append(string.Format("[{0}]", currentPage));
    70 dict[currentPageStr] = currentPage;
    71 output.AppendFormat("<span class=\"current\">{0}</span>", currentPage);
    72 }
    73 else
    74 {
    75 //一般页处理
    76 dict[currentPageStr] = currentPage + i - currint;
    77 output.Append(html.RouteLink((currentPage + i - currint).ToString(), dict));
    78 }
    79 output.Append(" ");
    80 }
    81 if (currentPage < totalPages)
    82 {
    83 //处理下一页的链接
    84 dict[currentPageStr] = currentPage + 1;
    85 output.Append(html.RouteLink("下一页", dict));
    86 }
    87 else
    88 {
    89 //output.Append("下一页");
    90 dict[currentPageStr] = currentPage;
    91 output.Append(html.RouteLink("下一页", dict));
    92 }
    93 output.Append(" ");
    94 if (currentPage != totalPages)
    95 {
    96 dict[currentPageStr] = totalPages;
    97 output.Append(html.RouteLink("末页", dict));
    98 }
    99 output.Append(" ");
    100 }
    101 output.AppendFormat("{0} / {1}", currentPage, totalPages);//这个统计加不加都行
    102 return output.ToString();
    103 }
    104 }
    105 }

    CSS:

    1 .pager
    2 {
    3 font-size: 12px;
    4 margin: 8px 0;
    5 padding: 3px 0 3px;
    6 text-align: left;
    7 }
    8
    9 .pager .current
    10 {
    11 background-color: #06c;
    12 border: 1px solid #009;
    13 color: #fff;
    14 font-weight: bold;
    15 margin-top: 4px;
    16 padding: 3px 5px;
    17 text-align: center;
    18 }
    19
    20 .pager a
    21 {
    22 margin: 4px 3px;
    23 border: 1px solid #9AAFE5;
    24 padding: 3px 5px;
    25 text-align: center;
    26 text-decoration: none;
    27 color: #2E6AB1;
    28 }
    29
    30 .pager .pagerInput
    31 {
    32 padding: 3px 0 0 0;
    33 border: 1px solid #9AAFE5;
    34 text-align: center;
    35 text-decoration: none;
    36 height: 16px;
    37 30px;
    38 }
    39 .pager .pagerButton
    40 {
    41 border: 1px solid #9AAFE5;
    42 cursor: pointer;
    43 }
    44

    View中使用:

    1 <div class="pager">
    2 <%= Html.Pager("page", 10,300))%>
    3 </div>
