Cnbruce的代码:
分页样例:[首页] [上页] [下页] [尾页] [页次:4/5页] [共86篇 20篇/页] 转到:_ 页
以下为公用代码,必须具备。
<%filepath=request.servervariables("path_info")%>
<%page=1 '设置变量初始值PAGE=1
page=request.querystring("page") 'page值为接受值
rs.PageSize = 20 '每页显示记录数
if Not IsEmpty(trim(Request("Page"))) then '如果PAGE已经初始化...
Page = CInt(Request("Page")) '接收PAGE并化为数字型赋给PAGE变量
if Page > rs.PageCount then '如果接收的页数大于总页数
rs.AbsolutePage = rs.PageCount '设置当前显示页等于最后页
elseif Page <= 0 then '如果page小于等于0
Page = 1 '设置PAGE等于第一页
else
rs.AbsolutePage = Page '如果大于零,显示当前页等于接收的页数
end if
End if
Page = rs.AbsolutePage%>
第一种分页
<%if rs.pagecount<>1 and rs.pagecount<>0 then%>'首先判断页总数不为1和0
<%if page>1 then%>
<%if page<rs.pagecount then %>
[<a Href="<%=filepath%>?Page=<% = 1%>">首页</a>]
[<a Href="<%=filepath%>?Page=<% = page -1 %>">上一页</a>]
[<a Href="<%=filepath%>?Page=<% = page + 1%>">下一页</a>]
[<a Href="<%=filepath%>?Page=<% = rs.PageCount%>">尾页</a>]
<%else%>
[<a Href="<%=filepath%>?Page=<% = 1%>">首页</a>]
[<a Href="<%=filepath%>?Page=<% = page -1 %>">上一页</a>]
[下一页] [尾页]
<% end if %>
<%else%>
[首页] [上一页]
[<a Href="<%=filepath%>?Page=<% = page + 1%>">下一页</a>]
[<a Href="<%=filepath%>?Page=<% = rs.PageCount%>">尾页</a>]
<%end if %>
<%else%>
[首页] [上一页] [下一页] [尾页]
<%end if%>
第二种分页
<%if rs.pagecount<>1 and rs.pagecount<>0 then%>
<%if page>1 then%>
[<a Href="<%=filepath%>?Page=<% = 1%>">首页</a>]
[<a Href="<%=filepath%>?Page=<% = page -1 %>">上一页</a>]
<%if page<rs.pagecount then %>
[<a Href="<%=filepath%>?Page=<% = page + 1%>">下一页</a>]
[<a Href="<%=filepath%>?Page=<% = rs.PageCount%>">尾页</a>]
<%else%>
[下一页] [尾页]
<% end if %>
<%else%>
[首页] [上一页]
[<a Href="<%=filepath%>?Page=<% = page + 1%>">下一页</a>]
[<a Href="<%=filepath%>?Page=<% = rs.PageCount%>">尾页</a>]
<%end if %>
<%else%>
[首页] [上一页] [下一页] [尾页]
<%end if%>
第三种
<%if rs.pagecount<>1 and rs.pagecount<>0 then%>
<%if page<rs.pagecount then%>
<%if page=1 then %>
[首页] [上一页]
<%else%>
[<a Href="<%=filepath%>?Page=<% = 1%>">首页</a>]
[<a Href="<%=filepath%>?Page=<% =page -1 %>">上一页</a>]
<% end if %>
[<a Href="<%=filepath%>?Page=<% = page + 1%>">下一页</a>]
[<a Href="<%=filepath%>?Page=<% = rs.PageCount%>">尾页</a>]
<%else%>
[<a Href="<%=filepath%>?Page=<% = 1%>">首页</a>]
[<a Href="<%=filepath%>?Page=<% =page -1 %>">上一页</a>]
[下一页] [尾页]
<%end if %>
<%else%>
