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;
}
