MVC异步分页代码 MVC异步分页代码分享
小锋神 人气:0想了解MVC异步分页代码讲解的相关内容吗，小锋神在本文为您仔细讲解MVC异步分页代码的相关知识和一些Code实例，欢迎阅读和指正，我们先划重点：MVC,异步,分页，下面大家一起来学习吧。
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="~/Content/NavPage.css" rel="stylesheet" />
<script src="~/Scripts/jquery-1.8.2.min.js"></script>
<script src="~/Scripts/jquery-ui-1.8.24.js"></script>
<script src="~/Scripts/jquery.easyui.min.js"></script>
<script src="~/Scripts/jquery.unobtrusive-ajax.js"></script>
<script src="~/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='javascript:void(0)'>修改</a>" +
"<a UId='" + data.Data[i].ID + "' href='javascript:void(0)'>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='{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='{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='{0}?pageIndex={1}&pageSize={2}'>{3}</a> ", redirectTo, currentPage, pageSize, currentPage);
}
else
{//一般页处理
output.AppendFormat("<a class='pageLink' href='{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='{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='{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;
}
