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
该怎么办？？？
想了好久都没有办法。。。求助

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
包裹起来，无非就是想和服务器（servlet）进行交换，把该订单的ID传给服务器进行删除；和服务器进行交换的方式一般有两种：form表单提交、Ajax。form表单提交一般用在点击“提交”后会跳转页面或刷新页面的情况；Ajax一般用在不跳转的情况下（整个页面大体不变的情况下）提交数据给服务器。
