Subject: [PATCH] fix(js): resolved JavaScript validation and dead code issues
- Added existence checks for jQuery selectors to prevent errors on missing elements
- Enhanced contact form validation with comprehensive error handling
- Replaced deprecated AjaxChimp with functional newsletter form handler
- Improved AJAX error handling with specific status codes and timeout management
- Removed hardcoded MailChimp URL from configuration
- Added email validation and user feedback for newsletter subscriptions
Fixes:
- Unused .clients slider initialization on non-existent elements
- Missing #contactForm element causing validation errors
- Dead AjaxChimp code targeting non-existent #mc-form
- Poor error handling in AJAX requests without timeout or specific messages
- Hardcoded placeholder MailChimp URL in configuration
The changes improved code reliability, user experience, and maintainability
by ensuring JavaScript only operates on existing DOM elements and provides
meaningful feedback to users.
