MVC异步分页代码分享
(编辑：jimmy 日期: 2024/5/10 浏览：3 次 )
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 "pageSize"]);
int pageIndex = Request["pageIndex"] == null "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="~/Content/NavPage.css" rel="stylesheet" />
<script src="/UploadFiles/2021-04-02/jquery-1.8.2.min.js">
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 "<a class='pageLink' href='{0}", redirectTo, pageSize);
}
if (currentPage > 1)
{//处理上一页的连接
output.AppendFormat("<a class='pageLink' href='{0}", 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='{0}", redirectTo, currentPage, pageSize, currentPage);
}
else
{//一般页处理
output.AppendFormat("<a class='pageLink' href='{0}", 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='{0}", 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='{0}", 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;
}
