分页程序
total_records 总记录数
everypage_records 每页显示条数
current_page 当前页数
url 要传递的url，这里可以含有要传递的变量，比如 "list.asp?" 或者"list.asp?keyword=key&"
程序调用比较简单，不过还是比php的麻烦，继续努力中

sub show_page(total_records,everypage_records,current_page,url)

if isnumeric (total_records) then
total_records=int(total_records)
else
total_records=0
end if

if isnumeric (everypage_records) then
everypage_records=int(everypage_records)
if everypage_records<=0 then
everypage_records=10
end if
else
everypage_records=10
end if

if isnumeric (current_page) then
current_page=int(current_page)
else
current_page=1
end if

取总页数，即最后一页
if total_records mod everypage_records=0 then
last_page=int(total_records/everypage_records)
else
last_page=int(total_records/everypage_records)+1
end if

判断 current_page 是否符合标准,并附值给page
if current_page>=last_page then
page=last_page
elseif current_page<=1 then
page=1
else
page=current_page
end if

上一页
if page<=0 then
prepg=0
else
prepg=page-1
end if
下一页
if page=last_page then
nextpg=0
else
nextpg=page+1
end if

本页开始记录
firstcount=prepg*everypage_records
本页结束记录
if nextpg>=1 then
lastcount=(nextpg-1)*everypage_records
else
lastcount=total_records
end if
开始分页导航条代码
pagenav=""
pagenav1=""
pagenav=pagenav&"显示第<b>"&firstcount&"-"&lastcount&"</b>条记录 共<b>"&total_records&"</b> 条记录"
pagenav1=pagenav1&"显示第<b>"&firstcount&"-"&lastcount&"</b>条记录 共<b>"&total_records&"</b> 条记录"

if last_page>1 then
当有前后页时
pagenav=pagenav&" <a href="&url&"page=1>首页</a> "
pagenav1=pagenav1&" <a href="&url&"page=1>首页</a> "
if prepg>=1 then
pagenav=pagenav&" <a href="&url&"page="&prepg&">前页</a> "
pagenav1=pagenav1&" <a href="&url&"page="&prepg&">前页</a> "
else
pagenav=pagenav&" 前页 "
pagenav1=pagenav1&" 前页 "
end if
if nextpg>=1 then
pagenav=pagenav&" <a href="&url&"page="&nextpg&">后页</a> "
pagenav1=pagenav1&" <a href="&url&"page="&nextpg&">后页</a> "
else
pagenav=pagenav&" 后页 "
pagenav1=pagenav1&" 后页 "
end if
pagenav=pagenav&" <a href="&url&"page="&last_page&">尾页</a> "
pagenav1=pagenav1&" <a href="&url&"page="&last_page&">尾页</a> "

pagenav=pagenav&"到第<input type=text name=text100 id=text100 value="&page&" size=3>页<input type=button name=button100 value=go onclick=window.location="""&url&"page=""+text100.value>"
pagenav=pagenav&" 共 "&last_page&" 页"

pagenav1=pagenav1&"到第<input type=text name=text101 id=text101 value="&page&" size=3>页<input type=button name=button101 value=go onclick=window.location="""&url&"page=""+text101.value>"
pagenav1=pagenav1&" 共 "&last_page&" 页"
