# TP-Link Omada Touch Kiosk - Refactored Version

## Overview

This is a refactored version of the TP-Link Omada Touch Kiosk application. The original monolithic implementation has been restructured into a modular architecture to improve maintainability, readability, and extensibility.

## Key Improvements

### 1. Modular JavaScript Architecture
- Separated concerns into distinct modules
- Eliminated duplicate function implementations
- Improved code organization and readability

### 2. Enhanced Maintainability
- Clear module responsibilities
- Easier to locate and modify specific functionality
- Reduced code coupling

### 3. Better Performance
- DOM element caching for improved performance
- Efficient event handling
- Optimized scroll interactions

### 4. Improved Extensibility
- Modular structure makes it easy to add new features
- Clear interfaces between components
- Reusable components

## Modules

### constants.js
Contains all application constants and configuration values.

### data.js
Holds product and family data structures.

### dom-cache.js
Manages DOM element caching for performance optimization.

### scroll-interaction.js
Handles vertical scroll interactions and focus management.

### gallery-manager.js
Manages product gallery display and information presentation.

### family-navigation.js
Controls family selection and navigation between views.

### app.js
Main application logic, initialization, and global event handling.

### utils.js
Utility functions and helper methods.

## Getting Started

1. Open `index.html` in a web browser
2. The application should load and function as expected
3. Use the test file `test-refactored.html` to verify module loading and basic functionality

## Testing

Run `test-refactored.html` to verify:
- All modules load correctly
- Basic functionality works as expected
- No JavaScript errors occur

## Migration from Original Version

The refactored version maintains all functionality of the original while providing:
- Better code organization
- Easier maintenance
- Improved performance
- Enhanced extensibility

## Browser Support

The application is designed to work in modern browsers that support:
- ES6 JavaScript features
- CSS3 animations and transitions
- Modern DOM APIs

## Development Guidelines

1. **Module Dependencies**: Modules are loaded in a specific order in index.html
2. **Global Objects**: Each module exposes a singleton instance globally
3. **Event Handling**: Most event handlers are centralized in app.js
4. **Data Access**: Product and family data is accessed through the global objects

## Contributing

When making changes to this refactored version:

1. Follow the existing modular structure
2. Maintain clear separation of concerns
3. Update documentation as needed
4. Test thoroughly to ensure no regressions
