客车网上售票系统（分解五）
1、今日完成任务:
(1)改签分解功能1：点击改签根据当前订单的出发地和目的地查询车票信息并显示（发车日期可以改动，出发地和目的地是固定不能变得）
(2)改签分解功能2:选好需要改动的车票点击查询页面的改签，跳转到详情页面分别显示需要改签前的车票信息和需要改签后的车票信息
(3)改签分解功能3：点击提交订单，显示当前订单的详细信息并提醒用户抓紧时间支付
(4)改签分解功能4：点击立即改签即改签成功并跳转回我的订单页面
2、核心源码:

3、遇到的问题:
(1)改签功能需要考虑的东西比较多，容易漏写功能
(2)很多想实现的效果因为能力有限没办法实现，需要前端技术
4、解决的方法:
(1)网上搜索12306改签流程实现
(2)技术能力方面需要利用这个暑假做提升
