如图：

 

1、控制器代码 

//    // GET: /AjaxUser/    shopEntities shop = new shopEntities();    public ActionResult Index()    {      return View();    }    public ActionResult loadjson()    {      int pageSize = Request["pageSize"] == null ? 10 : int.Parse(Request["pageSize"]);      int pageIndex = Request["pageIndex"] == null ? 1 : int.Parse(Request["pageIndex"]);      int totalCount = shop.tbl_admin.Count();       //给前台userinfo所有的数据，并且是json格式      var allorder = shop.tbl_admin.OrderBy(u=>u.id)        .Skip(pageSize*(pageIndex-1))        .Take(pageSize)        .ToList();      //接受一个对像，内部把此对象使用javaScript序列化类对象志字符串，发送到前台      var data = from u in allorder select new { u.id,u.realname,u.sex};      string strNav = PageNavHelper.ShowPageNavigate(pageIndex,pageSize,totalCount);      var result = new {Data=data, NavStr=strNav };      return Json(result, JsonRequestBehavior.AllowGet);    }

2、Html代码 

@{  Layout = null;}<!DOCTYPE html><html><head>  <meta name="viewport" content="width=device-width" />  <title>Index</title>  <link href="https:/article/~/Content/NavPage.css" rel="stylesheet" />  <script src="https:/article/~/Scripts/jquery-1.8.2.min.js"></script>  <script src="https:/article/~/Scripts/jquery-ui-1.8.24.js"></script>  <script src="https:/article/~/Scripts/jquery.easyui.min.js"></script>  <script src="https:/article/~/Scripts/jquery.unobtrusive-ajax.js"></script>  <script src="https:/article/~/Scripts/jquery.validate.unobtrusive.js"></script>  <script type="text/javascript">    $(function () {      //页面加载完成后从后如加载当前页数据      initTable();    });  //初始化表格数据    function initTable(queryData)     {      $.getJSON("/AjaxUser/loadjson",queryData, function (data) {        var tb = $("#tbList");        //先移除旧的，添加新的        $("#tbList tr[type=data]").remove();        for (var i = 0; i < data.Data.length; i++)        {           var strTr = "<tr type='data'>";          strTr += "<td>" + data.Data[i].id + "</td>";          strTr += "<td>" + data.Data[i].realname + "</td>";          strTr += "<td>" + data.Data[i].sex + "</td>";          strTr += "<td><a UId='" + data.Data[i].id + "' href=''>修改</a>" +"<a UId='" + data.Data[i].ID + "' href=''>删除</a></td>";          strTr += "</tr>";          tb.append(strTr);        }        $("#Nav").html(data.NavStr);        //绑定分页标签的点击事件        $(".pageLink").click(function () {          //把页码弹出来          var strHref = $(this).attr("href");          var queryStr = strHref.substr(strHref.indexOf('?') + 1);          //alert(queryStr);          initTable(queryStr);          return false;        });      });    }  </script></head><body>  <div>    <table id="tbList">      <tr>        <td>id</td>        <td>姓名</td>        <td>性别</td>        <td>操作</td>      </tr>    </table>    <div id="Nav" class="paginator">     </div>       </div></body></html>

3、分页类

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Web;namespace MvcTest4.Models{  public class PageNavHelper  {    //主要就是输出分页的超级链接的标签    //自定义分页Helper扩展    public static string ShowPageNavigate(int currentPage, int pageSize, int totalCount)    {      var redirectTo = HttpContext.Current.Request.Url.AbsolutePath;      pageSize = pageSize <= 0 ? 3 : pageSize;      var totalPages = Math.Max((totalCount + pageSize - 1) / pageSize, 1); //总页数       var output = new StringBuilder();      if (totalPages > 1)      {        //if (currentPage != 1)        {//处理首页连接          output.AppendFormat("<a class='pageLink' href='https:/article/{0}?pageIndex=1&pageSize={1}'>首页</a> ", redirectTo, pageSize);        }        if (currentPage > 1)        {//处理上一页的连接          output.AppendFormat("<a class='pageLink' href='https:/article/{0}?pageIndex={1}&pageSize={2}'>上一页</a> ", redirectTo, currentPage - 1, pageSize);        }        else        {          // output.Append("<span class='pageLink'>上一页</span>");        }        output.Append(" ");        int currint = 5;        for (int i = 0; i <= 10; i++)        {//一共最多显示10个页码，前面5个，后面5个          if ((currentPage + i - currint) >= 1 && (currentPage + i - currint) <= totalPages)          {if (currint == i){//当前页处理  //output.Append(string.Format("[{0}]", currentPage));  output.AppendFormat("<a class='cpb' href='https:/article/{0}?pageIndex={1}&pageSize={2}'>{3}</a> ", redirectTo, currentPage, pageSize, currentPage);}else{//一般页处理  output.AppendFormat("<a class='pageLink' href='https:/article/{0}?pageIndex={1}&pageSize={2}'>{3}</a> ", redirectTo, currentPage + i - currint, pageSize, currentPage + i - currint);}          }          output.Append(" ");        }        if (currentPage < totalPages)        {//处理下一页的链接          output.AppendFormat("<a class='pageLink' href='https:/article/{0}?pageIndex={1}&pageSize={2}'>下一页</a> ", redirectTo, currentPage + 1, pageSize);        }        else        {          //output.Append("<span class='pageLink'>下一页</span>");        }        output.Append(" ");        if (currentPage != totalPages)        {          output.AppendFormat("<a class='pageLink' href='https:/article/{0}?pageIndex={1}&pageSize={2}'>末页</a> ", redirectTo, totalPages, pageSize);        }        output.Append(" ");      }      output.AppendFormat("第{0}页 / 共{1}页", currentPage, totalPages);//这个统计加不加都行       return output.ToString();    }  }}

4、分页CSS 

body {} .paginator {  font: 12px Arial, Helvetica, sans-serif;  padding: 10px 20px 10px 0;  margin: 0px;}  .paginator a {    border: solid 1px #ccc;    color: #0063dc;    cursor: pointer;    text-decoration: none;  }    .paginator a:visited {      padding: 1px 6px;      border: solid 1px #ddd;      background: #fff;      text-decoration: none;    }  .paginator .cpb {    border: 1px solid #F50;    font-weight: 700;    color: #F50;    background-color: #ffeee5;  }  .paginator a:hover {    border: solid 1px #F50;    color: #f60;    text-decoration: none;  }  .paginator a, .paginator a:visited, .paginator .cpb, .paginator a:hover {    float: left;    height: 16px;    line-height: 16px;    min-width: 10px;    _width: 10px;    margin-right: 5px;    text-align: center;    white-space: nowrap;    font-size: 12px;    font-family: Arial,SimSun;    padding: 0 3px;  }

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
