?后臺的調用方法:

//生成 分頁的標簽
NavString= Common.LaomaPager.ShowPageNavigate(pageSize, pageIndex, allCount);

前臺的調用方法:

<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>
