为很多中小企业写站点，一般产品展示是个大项目，那么做成的页面也就不同。
要不就是横排来几个，要不就是竖排来几个，甚至全站要翻来覆去的搞个好几次，麻烦也很累。
索性写个函数能缓解一下，于是就成了下面：

程序代码

<%
function showpros(tablename,topnum,fildname,loopnum,typenum)
Set rs = Server.CreateObject ("ADODB.Recordset")
sql = "Select top "&topnum&" * from "&tablename
rs.Open sql,conn,1,1
if rs.eof and rs.bof then
response.Write("暂时无该记录")
else
response.Write("<table width='100%'>")
for i=1 to rs.recordcount
if (i mod loopnum=1) then
response.write"<tr>"
end if
select case typenum
case "1"
response.Write("<td><table width='100%'><tr><td bgcolor=red width='50%'>")
response.Write(rs(""&fildname&""))
response.Write("</td><td bgcolor=black>")
response.Write("方式1之"&i&"记录")'此处的“方式1”可以替换显示为其余字段的值
response.Write("</td></tr>")'如果字段比较多，继续添加新个表格行来显示
response.Write("</table></td>")
case "2"
response.Write("<td><table width='100%'><tr><td bgcolor=red>")
response.Write(rs(""&fildname&""))
response.Write("</td></tr>")
response.Write("<tr><td bgcolor=black>")
response.Write("方式2之"&i&"记录")
response.Write("</td></tr>")
response.Write("</table></td>")
end select
if (i mod loopnum=0) then
response.write"</tr>"
end if
rs.movenext
next
response.Write("</table>")
end if
rs.close
Set rs = Nothing
end function
%>

参数说明：
showpros(tablename,topnum,fildname,loopnum,typenum)
whichpro为选择何类型的产品种类
topnum表示提取多少条记录
fildname表示调试显示的字段，具体应用的时候可以省去该参数，在函数内部直接使用
loopnum表示显示的循环每行的记录条数
typenum表示循环显示的方法：目前分了两类，横向并列、纵向并列显示同一数据记录行的不同记录
引用示例如下：

程序代码

<%
if request.form("submit")<>"" then
topnum=request.form("topnum")
loopnum=request.form("loopnum")
typenum=request.form("typenum")
else
topnum=8
loopnum=2
typenum=1
end if
%>
<%call showpros("cn_products",topnum,"p_name",loopnum,typenum)%>
<form action=index.asp method=post>
显示的记录总数：<input name=topnum value=<%=topnum%>>
显示的行循环数：<input name=loopnum value=<%=loopnum%>>
显示的方式类型：<select name=typenum>
<option value="1">方式1</option>
<option value="2">方式2</option>
</select>
<input type=submit name=submit value=Sure>
</form>
