ASP中如何使用inputbox

<%
if request.QueryString("act")="act" then
   input=request.querystring("int")
   if  input=""  then
      response.write"空值"
    else
      response.write "input="&input
    end if
else
%>

<script language="javascript">
input=prompt("请输入姓名","");
if (input.length>0)
{
  location="?act=act&int="+input;
}
</script>
<%
end if
%>
