主要是(roleAssign.jsp , selectUserToRole.jsp )2个jsp页面的JS方法调用比较复杂，主页面要获取弹窗页面的数据
var pre_ids = h.find("iframe")[0].contentWindow.pre_ids;
var ids = h.find("iframe")[0].contentWindow.ids;
top.$.jBox.open("iframe:${ctx}/sys/role/usertorole?id=${role.id}",... 这个selectUserToRole.jsp页面就在一个iframe里面。
里面很多JQuery方法见注解。var officeNodes 的初始方法比较厉害，直接使用<c:forEach >

selectUserToRole.jsp
一个技巧点：为什么要把 model.addAttribute("selectIds", Collections3.extractToString(userList, "name", ",")); ， 注意这里提取的是name, 我开始还以为作者失误，其实是故意的。因为在后面保存角色和用户的对应关系时，ids里面的name就找不到相应的user,也就是保存了新添加的用户。 User user = systemService.assignUserToRole(role, systemService.getUser(idsArr[i]));
