th_update.asp页面代码就写了这么点，剩下的不会写：



<%
If Request.Form("delid")="" or isnull(Request.Form("delid")) or isempty(Request.Form("delid")) then
response.write "<script>alert('请选择要修改的信息!');history.go(-1);</script>"
else
arrdel=Request("delid")
basket_count=Request("basket_count")
thcount=Request("thcount")
sql="update venshop_basket set basket_count='"+thcount+"' where basket_id='"+arrdel+"'"
conn.Execute sql
set conn=nothing
response.write "<script language=JavaScript>alert('修改成功！');location.href=ad_sub.asp;<script>"
response.Redirect("ad_sub.asp")
end if
%>
这样不是批量修改，只能单独更新，且更新出来的数据也不对，数据库里显示“20,”不知道为什么后面带个逗号。展开
