前言

继续对电商购物平台进行改进和升级，加上用户登录及注册页面

（虽然前几次升级好像没发

一个有点小复杂的东西，完成的不是很完善

---

一、实验内容

完成一个电商购物平台的登录注册窗体，点击“点我注册”，显示注册窗体，用户输入用户信息，点击提交后到达显示用户信息的窗体。窗体如图2所示。

在内容2的基础上，用户点击登录注册窗体的登录按钮，到达商品信息查询的窗体，窗体如图3所示

二、实验思路

和计算器的类似，按照所给的图（需求），写出需要的组件（也就是用户名，密码，登录，注册等按钮），添加窗体所需要的库，按照需求摆好按钮所需要的位置，用监听器将功能部署到按钮上去

让按钮可以实现需要的功能

三、实验代码

总结

一个奇怪的东西，还没有完全完成（不知道为什么有的按钮不按照我想象的形式出现，让我再看看改改（×）
