Answer 1

<!--判断当前的窗体的请求是否为空-->
if request.form<>"" then
Chk_badword=split(Form_Badword,"‖")
<!--执行循环语句，判断name是否在窗体发送的请求里面-->
FOR EACH name IN Request.Form
<!--for循环-->
for i=0 to ubound(Chk_badword)
<！--判断，把窗体的请求，按钮的参数传给LCase函数-->
If Instr(LCase(request.form(name)),Chk_badword(i))<>0 Then
Select Case Err_Message
Case "1"
Response.Write "<Script Language=JavaScript>alert('出错了！表单 "&name&" 的值中包含非法字符串！\n\n请不要在表单中出现： % & * # ( ) 等非法字符！');window.close();</Script>"
Case "2"
Response.Write "<Script Language=JavaScript>location.href='"&Err_Web&"'</Script>"
Case "3"
Response.Write "<Script Language=JavaScript>alert('出错了！参数 "&name&"的值中包含非法字符串！\n\n请不要在表单中出现： % & * # ( ) 等非法字符！');location.href='"&Err_Web&"';</Script>"
End Select
Response.End
End If
NEXT
NEXT
end if
%>

这段代码应该是考察循环语句的使用。
