这是一个订单展示然后有一个按钮取消订单的
这个链接按钮应该是放在form里
但是因为我的订单是从数据库里调的
不知道有多少个订单
所以form也应该是动态生成的
像我这样写可以只用了一个form 一个订单
要是把form放到循环里就没用了
就是下面这样
ReserveList里面已经存好了多个订单对象

for(int i=0;i< ReserveList.size();i++) {out.println("<form name='form7'action='/g0103/servlet/servBDReserveCancel?rnum="+ReserveList.get(0).getReserveNum()+"' method='post'><a href='javascript:form"+(i+7)+".submit()' class='btn_buy' >取消</a></form>");}

该怎么办？？？
想了好久都没有办法。。。求助

回复讨论(解决方案)

你应该到JavaEE模块里去问这个问题，移步 http://bbs.csdn.net/forums/J2EE。
另外，你都说了是 MVC， view和model分离：
页面HTML内容应该在JSP中写，
在servlet中把 ReserveList对象传过去用EL、JSTL展示即可。

至于你遇到的问题，你可以使用Ajax，而不直接使用Form提交表单的方式；
像一般的列表页，每个行（item）都有个删除的按钮，点击删除按钮，
就通过Ajax把这个item的ID传到服务器进行删除，然后反馈等等。

你把每个订单都用
