[基础]由复选框实现的批量删除

批量删除：

选中多个复选框：

每一条记录：<input type="checkbox" name="delete" value="${Hotel.id}"/>

function doDelete(){var inputs = document.getElementsByName("delete");var flag = false;var ids = "";for(var i =0 ; i<inputs.length;i++ ){if(inputs[i].checked){flag = true;if(ids == ""){ids = inputs[i].value;}else{ids += ","+inputs[i].value;}}}if(!flag){alert("Please select the data you want to delete");return;}if(!confirm("Are you confirm to delete?")) return;$("doAction").value = "delete";document.forms[0].action += "?ids=" + ids;document.forms[0].submit();}

删除时先由Id查出对象，再删除对象，即可实现删除！

else if("delete".equalsIgnoreCase(doAction)){String deleteIds = request.getParameter("deleteIds");String[] ids = deleteIds.split(",");List<UnsubscribeEmail> list = (List<UnsubscribeEmail>)session.getAttribute(MyConstants.UN_SUBSCRIBE_EMAIL); //数据列表for(String str : ids){Integer id = Integer.parseInt(str);UnsubscribeEmail u = unsubscribeEmailFacade.findById(id);if(u!=null){unsubscribeEmailFacade.delete(u);for(UnsubscribeEmail uEmail : list){if(uEmail.getId().equals(id)){list.remove(uEmail);   //将要删除的数据的对象从列表中删除break;}}}}request.setAttribute(MyConstants.MESSAGE_KEY, "Delete Success.");session.setAttribute(MyConstants.UN_SUBSCRIBE_EMAIL, list);}return "success";}

public BookingHotel findById(String id) throws Exception {DetachedCriteria detachedCriteria = DetachedCriteria.forClass(BookingHotel.class);detachedCriteria.add(Expression.eq("id", id));List<BookingHotel> list = this.getHibernateTemplate().findByCriteria(detachedCriteria);if (list.size() > 0) {return list.get(0);}return null;}

比较基础的东西。。。
