做网页有时我们需要将多个表单方在同一个页面 
处理表单的程序页怎样才知道那个表单被提交了并作相应的处理呢? 
下面是一个例子: 
'''''''''''''''''''''form.asp 
<%@LANGUAGE="VBSCRIPT" CODEPAGE="936"%> 
<script language="vbscript" runat="server"> 
sub chuli() 
if request.QueryString("formid")=1 then 
response.Write(request.Form("textfield")) 
elseif request.QueryString("formid")=2 then 
response.Write(request.Form("textfield2")) 
end if 
end sub 
</script> 
<html><head><title>一个页面多个表单的提交</title></head> 
<body> 
<table width="300" border="0" cellspacing="0" cellpadding="0" align="center"> 
<tr> 
<td><form name="form1" method="post" action="form.asp?formid=1"> 
<input type="text" name="textfield"> 
<input type="submit" name="Submit" value="提交"> 
</form></td> 
</tr> 
<tr> 
<td> </td> 
</tr> 
<tr> 
<td><form name="form2" method="post" action="form1.asp?formid=2"> 
<input type="text" name="textfield2"> 
<input type="submit" name="Submit2" value="提交"> 
</form></td> 
</tr> 
<tr> 
<td> </td> 
</tr> 
<tr> 
<td> 
<% 
chuli '调用服务器端过程 
%> 
</td> 
</tr> 
</table> 
</body> 
</html>
