问高手,怎么在jsp同一个页面内穿多个值？

设定一个BUTTON 按钮 ONCLICK 事件里面 DOCUMENT.FORMS[0].ACTION= **.JSP?A1=**&A2=**&A3=88;DOCUMENT.FORMS[0].SUBMIT();

不用onChange,在都选完后,点个按钮一起提交不就行了
用AJAX实现最简单,实时取数据,
HTML文件代码,
<html>
  <head>

当然没有必要,这只是连动下拉AJAX实现的例子,应用到自己的项目中并不需要这么多代码,代码中注释有很多的.
ladofwind(随风) 说的对,提交一下就行了,但提交要刷新页面,很不爽,
来来，给你小改一下，拿去吧<%@ page contentType="text/html; charset=gb2312"%>
<%
String s1 = request.getParameter("S1");
String s2 = request.getParameter("S2");
String s3 = request.getParameter("S3");
%><html>
<body>
<form name="form" method="POST" action="list.jsp">
<select name="S1" width="50" size="1" onChange="document.form.submit()">
<option value="a1" <%=s1!=null&&s1.equals("a1")?"selected":""%>> a1 </option>
<option value="b1" <%=s1!=null&&s1.equals("b1")?"selected":""%>> b1 </option>
</select>
<select name="S2" width="50" size="1" onChange="document.form.submit()">
<option value="a2" <%=s2!=null&&s2.equals("a2")?"selected":""%>> a2 </option>
<option value="b2" <%=s2!=null&&s2.equals("b2")?"selected":""%>> b2 </option>
</select>
<select name="S3" width="50" size="1" onChange="document.form.submit()">
<option value="a3" <%=s3!=null&&s3.equals("a3")?"selected":""%>> a3 </option>
<option value="b3" <%=s3!=null&&s3.equals("b3")?"selected":""%>> b3 </option>
</select>
</form>
S1:<%=s1%>
<br>
S2:<%=s2%>
<br>
S3:<%=s3%>
<br>
</body>
</html>
不同意kevin的做法这样做没次都要提交到服务器  那么简单的业务我想没必要增加服务器的负担 JAVASCRIPT 解决我想更好
