頁(yè)碼導(dǎo)航，先看顯示效果：
算法要求：
1、頁(yè)數(shù)小于等于1時(shí)不顯示；
2、頁(yè)數(shù)大于10時(shí)，自動(dòng)縮短。
具體代碼如下：
復(fù)制代碼 代碼如下:

if (intPageCount > 1)

{

CSS樣式：
復(fù)制代碼 代碼如下:
.div_pagenavgation{
margin-top:5px;
line-height:20px;
float:right;
}
.div_pagenavgation a{
float:left;
text-decoration:none;
color:#06F;
margin-left:5px;
padding-left:5px;
padding-right:5px;
height:20px;
text-align:center;
display:block;
border:1px #CCC solid;
}
.div_pagenavgation .dotted{
float:left;
}
.div_pagenavgation .current{
float:left;
margin-left:5px;
padding-left:5px;
padding-right:5px;
height:20px;
text-align:center;
display:block;
border:1px #CCC solid ;
background-color:#0080C0;
color:#FFF;
}
.div_pagenavgation .disabled{
float:left;
margin-left:5px;
padding-left:5px;
padding-right:5px;
height:20px;
text-align:center;
display:block;
border:1px #CCC solid;
color:#CCC;
}
產(chǎn)生的HTML如下：

a href="?m=logpage=1">1/a>
a href="?m=logpage=2">2/a>
