分页类与前台和后台的调用方法

using System;
using System.Text;

namespace WebDemo.Common

public class LaomaPager
{
/// <summary>

var output = new StringBuilder();

// 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);

}
}

}
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();
}
}
}

 后台的调用方法:

//生成 分页的标签
NavString= Common.LaomaPager.ShowPageNavigate(pageSize, pageIndex, allCount);

前台的调用方法:

<style type="text/css">
.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;
}
</style>
