在asp中制作留言板,如何判断多个文本框为空??
<%if request.Form("contenttop")="" or request.Form("content")="" then
Response.Write("<script>alert('留言标题或留言内容不能为空!');history.back(-1);</script>")
Response.End()
if request.Form("QQ")="" or request.Form("fromwhere")="" then
Response.Write("<script>alert('如需本园联系您,请您留下您的联系方式!');</script>")
Response.End()
End if
name=request.Form("name") '读取表单元素
Email=request.Form("email")
fromwhere=request.Form("fromwhere")
QQ=request.Form("qq")
contenttop=request.Form("contenttop")
content=request.Form("content")
exec="insert into yhly(name,Email,fromwhere,qq,contenttop,content) values('"+name+"','"+Email+"','"+formwhere+"','"+QQ+"','"+contenttop+"','"+content+"')"
conn.execute exec
conn.close
set conn=nothing
Response.Write("<script>alert('留言添加成功!!');</script>")
%>
我只要加上红色那段代码,就会报错,请教各位大侠怎么回事呢???
