Refactor switch-case duplication, optimize getFieldEmpty

[pixel365]

Description: This PR introduces two key changes to improve code maintainability and efficiency:

1. Merged duplicate switch-case branches:
   Several case statements in the switch block were redundant (handling the same logic for different event types). These cases have been grouped together, which makes the code more concise and easier to maintain.

2. Optimized getFieldEmpty function:
   The getFieldEmpty function has been simplified for better performance and readability. The new implementation eliminates unnecessary checks and optimizes the flow..

Benefits:

Improved code readability and maintainability.
Reduced duplication of logic, making it easier to extend or modify in the future.
Slight optimization in the getFieldEmpty function, leading to cleaner and faster execution.

Additional notes:

This PR does not introduce any breaking changes.
No new dependencies have been added.

Thanks for the PR, but this doesn't look like something that's worth the effort for us to push through. It seems to be more stylistic/personal preference than a meaningful change that addresses a real problem.
