JPager.Net MVC好用的轻量级分页控件，好用到你无法想象，轻量到你无法想象。
JPager.Net MVC好用的轻量级分页控件，实现非常简单，使用也非常简单。
JPager.Net MVC好用的轻量级分页控件，代码精心推敲，经多人反复建议修改，最终成型使用中。非常好用分享给大家。源代码一共放出来。先上个效果图：
JPager.Net MVC好用的轻量级分页控件JPager.Net .dll核心代码
PagerInBase.cs
namespace JPager.Net
{
/// <summary>
/// 分页基础类
/// </summary>
public class PagerInBase
{
/// <summary>
/// 当前页
/// </summary>
public int PageIndex { get; set; }
/// <summary>
/// 页数
/// </summary>
public int PageSize { get; set; }
//跳过序列中指定数量的元素
public int Skip => (PageIndex - 1) * PageSize;
/// <summary>
/// 请求URL
/// </summary>
public string RequetUrl => System.Web.HttpContext.Current.Request.Url.OriginalString;
/// <summary>
/// 构造函数给当前页和页数初始化
/// </summary>
public PagerInBase()
{
if (PageIndex == 0) PageIndex = 1;
if (PageSize == 0) PageSize = 10;
}
}
}
PagerResult.cs
using System;
using System.Collections.Generic;
using System.Text;
namespace JPager.Net
{
/// <summary>
/// ULR拼装
/// </summary>
internal static class Exts
{
public static string GetUrl(this string url, int curIndex, int reps)
{
return url.Replace("pageindex=" + curIndex.ToString(), "pageindex=" + reps.ToString());
}
}
/// <summary>
/// 分页核心代码
/// </summary>
/// <typeparam name="T"></typeparam>
public class PagerResult<T>
{
public int Code { get; set; }
public int Total { get; set; }
public IEnumerable<T> DataList { get; set; }
public int PageSize { get; set; }
public int PageIndex { get; set; }
public string RequestUrl { get; set; }
/// <summary>
/// 分页页码Html
/// </summary>
/// <param name="cssClass">默认样式：jpager</param>
/// <returns></returns>
public string PagerHtml(string cssClass="jpager")
{
if (PageIndex == 0) PageIndex = 1;
if (RequestUrl.IndexOf("?", StringComparison.Ordinal) == -1) RequestUrl += "?pageindex=1";
else
if (RequestUrl.IndexOf("&pageindex", StringComparison.Ordinal) == -1&& RequestUrl.IndexOf("?pageindex", StringComparison.Ordinal) == -1) RequestUrl += "&pageindex=1";
var html = new StringBuilder();
html.AppendFormat("<span class='{0}'>", cssClass);
var pageLen = Math.Ceiling((double)Total / PageSize);
html.AppendFormat("<a href='{0}'> 首页 </a>", RequestUrl.GetUrl(PageIndex,1));
html.AppendFormat("<a href='{0}'> 上页 </a>", RequestUrl.GetUrl(PageIndex, PageIndex < 2 ? 1 : PageIndex - 1));
var si = PageIndex <= 6 ? 1 : PageIndex - 5;
var ei = si + 9;
while (si <= pageLen && si <= ei)
html.AppendFormat(
si == PageIndex
? "<a style='color:black;border:none;' href='{0}'> {1} </a>"
: "<a href='{0}'> {1} </a>", RequestUrl.GetUrl(PageIndex, si), si++);
html.AppendFormat("<a href='{0}'> 下页 </a>", RequestUrl.GetUrl(PageIndex, (int)(PageIndex > pageLen - 1 ? pageLen : PageIndex + 1)));
html.AppendFormat("<a href='{0}'> 尾页 </a>",
Math.Abs(Total) <= 0
? RequestUrl.GetUrl(PageIndex, 1)
: RequestUrl.GetUrl(PageIndex, (int) pageLen));
html.Append(@"</span>");
return html.ToString();
}
}
}
使用方法：
HomeController.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web.Mvc;
using JPager.Net;
using JPager.Net.Web.Models;
namespace JPager.Net.Web.Controllers
{
public class HomeController : Controller
{
public ActionResult Index(UserParams param)
{
//每页显示的条数默认10
//param.PageSize = 10;
//保存搜索条件
ViewBag.SearchName = param.Name;
ViewBag.SearchAge = param.Age;
//获取数据集合
var list = PageContent();
//根据条件检索
var query = param.Name!=null ?
list.Where(t=>t.Name.Contains(param.Name)).ToList() :
list.ToList();
//分页数据
var data = query.Skip(param.Skip).Take(param.PageSize);
//总页数
var count = query.Count;
var res = new PagerResult<User> { Code = 0, DataList = data, Total = count,
PageSize = param.PageSize,PageIndex = param.PageIndex,RequestUrl = param.RequetUrl};
return View(res);
}
//测试数据
public List<User> PageContent()
{
var list = new List<User>();
for (var t = 0; t < 10000; t++)
{
list.Add(new User
{
Id = t,
Name = "Joye.net"+t.ToString(),
Age = t + 10,
Score = t,
Address = "http://yinrq.cnblogs.com/",
AddTime = DateTime.Now
});
}
return list;
}
}
}
Models文件夹建User.cs和UserParams.cs
User.cs
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
namespace JPager.Net.Web.Models
{
public class UserParams:JPager.Net.PagerInBase
{
public int Id { get; set; }
public string Name { get; set; }
public int ? Age { get; set; }
public int Score { get; set; }
public string Address { get; set; }
public DateTime AddTime { get; set; }
}
}
UserParams.cs
using System;
namespace JPager.Net.Web.Models
{
public class User
{
public int Id { get; set; }
public string Name { get; set; }
public int Age { get; set; }
public int Score { get; set; }
public string Address { get; set; }
public DateTime AddTime { get; set; }
}
}
view显示
@model JPager.Net.PagerResult<JPager.Net.Web.Models.User>
@{
ViewBag.Title = "Index";
}
<h2>JPager.Net MVC好用的轻量级分页控件</h2>

<div>
@Html.Raw(Model.PagerHtml()) 共 @Model.Total 条
