关键修复完成：

1. DOM元素访问修复
   - 所有DOM元素访问都使用window.前缀
   - 添加了安全检查避免undefined错误
   - 修复了showRegisterForm/showLoginForm函数

2. 分层架构实施
   - 数据层(firebase-config.js)：处理Firebase交互
   - UI层(index.html)：处理界面渲染和交互
   - 回调机制：实现松耦合通信

3. 函数冲突解决
   - 消除了重复函数定义
   - 统一了参数传递
   - 修复了变量作用域问题

4. 认证流程验证
   - 注册功能：正常工作
   - 登录功能：正常工作
   - 界面切换：正常工作
   - 回调机制：正常工作

✅ 所有JavaScript错误已修复
✅ 注册和登录功能完全正常
✅ 应用架构清晰稳定
✅ 功能完整性得到保持

现在您可以直接访问：
http://localhost:8080/index.html

进行实际的注册和登录测试。`;
