MVC异步分页的示例分析

这篇文章将为大家详细讲解有关MVC异步分页的示例分析，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

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;}                    
    
      
        
id
        
姓名
        
性别
        
操作
      
    
    
     
       

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("首页 ", redirectTo, pageSize);        }        if (currentPage > 1)        {//处理上一页的连接          output.AppendFormat("上一页 ", redirectTo, currentPage - 1, pageSize);        }        else        {          // output.Append("上一页");        }        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("{3} ", redirectTo, currentPage, pageSize, currentPage);            }            else            {//一般页处理              output.AppendFormat("{3} ", redirectTo, currentPage + i - currint, pageSize, currentPage + i - currint);            }          }          output.Append(" ");        }        if (currentPage < totalPages)        {//处理下一页的链接          output.AppendFormat("下一页 ", redirectTo, currentPage + 1, pageSize);        }        else        {          //output.Append("下一页");        }        output.Append(" ");        if (currentPage != totalPages)        {          output.AppendFormat("末页 ", 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;  }
