ASP中一个页面多个表单如何提交

代码如下，前面是一个三级联动，三个表单，最后一个表单的数据从数据库读出，提交是如何能同时提交？
<form name="myform" method="post" action="saveziliao.asp">
<%
set rsa=server.CreateObject("adodb.recordset")
sq="select * from edu_c"
rsa.open sq,conn,1,1
%>
<select name="class1" onChange="changeclass2();changeclass3()">
<option value="" selected>一级</option>
<%
while not rsa.eof
%>
<option value="<%=rsa("c_name")%>"><%=rsa("c_name")
%>
</option>
<%
rsa.movenext
wend
rsa.close
%>
</select>
<select name="class2" onChange="changeclass3();changeclass4();changeclass5()">
<option value="" selected>二级</option>
</select>
<select name="class3" onChange="changeclass4();changeclass5()">
<option value="" selected>三级</option>
</select>

<%
sql="select * from edu_co"
rsa.open sql,conn,1,1
num=rsa.recordcount
str=""
for i=1 to rsa.recordcount
str=str&rsa("c_name")&"-"&rsa("co_name")&","
if rsa.eof then exit for
rsa.movenext
next
rsa.close
%>
<%
sql="select * from edu_s"
rsa.open sql,conn,1,1
num2=rsa.recordcount
str2=""
for i=1 to rsa.recordcount
str2=str2&rsa("co_name")&"-"&rsa("s_name")&","
if rsa.eof then exit for
rsa.movenext
next
rsa.close

<script LANGUAGE="javascript">

arr="<%=str%>".split(",");
a=arr.length
ar=new Array()
for (i=0;i<a;i++){
ar[i]=arr[i].split("-");

onecount2=ar2.length;

function changeclass2() {
document.myform.class2.length=0
lid=myform.class1.value;
for (i=0;i<onecount;i++) {
if (ar[i][0] == lid) {
document.myform.class2.options.add(new Option(ar[i][1], ar[i][1]));

<input name="Submit" type="submit" id="Submit" onClick="return RegForm()" value="修改">
</form>

Answer 1

先提交一个表单，保存相关信息和数据库查询信息，返回后形成一个具有联动效果的网页，不过这个网页是另一个网页。是可以成功的吧。

Answer 2

不能同时提交, 每个表单提交动作都将产生一次HTTP请求, 但浏览器同一时间只能处理一个. 可以考虑先用Ajax提交两个,等返回以后再将第三个表单由浏览器提交.
