Java 在同一页面中的何处存储选定元素值？,java,jsp,jquery,servlets,url-rewriting,Java,Jsp,Jquery,Servlets,Url Rewriting,我有main.jsp，其中包括4个jsp页面，即company.jsp、software.jsp、location.jsp、dept.jsp，最后是提交按钮，该按钮将重定向到另一个jsp页面 注意：在company.jsp和Software.jsp中，只需单击一个单选按钮 在location.jsp中，dept.jsp具有多个复选框 我想改进我的搜索 大概是这样的： 我想知道，当根据公司选择的软件在company.jsp中选择一个单选按钮时，将从数据库中显示。当选择软件时，将根据数据库显示带

我有main.jsp，其中包括4个jsp页面，即company.jsp、software.jsp、location.jsp、dept.jsp
，最后是提交按钮，该按钮将重定向到另一个jsp页面 注意：在company.jsp和Software.jsp中，只需单击一个单选按钮
在location.jsp中，dept.jsp具有多个复选框

我想改进我的搜索 大概是这样的：

我想知道，当根据公司选择的软件在company.jsp中选择一个单选按钮时，将从数据库中显示。当选择软件时，将根据数据库显示带有复选框的位置。如果选择了位置，则将根据数据库显示部门，依此类推。。 我曾尝试使用jquery，其中选中的单选按钮作为参数添加到url中，但这是一种糟糕的做法，因为我正在通过
window.location.href
更改url。这是不好的做法
使用servlet或jquery还有其他想法吗？
