Card Holder:
HTML: Input id changed to card-holder-input.
JavaScript: Still references #card-holder for updating the display.
Card Expiration Date:
HTML: Added a
for showing the formatted date.
JavaScript: Still references .card-expiration-date div, which wasn't present initially.
Redundant or Unused Code:
The setTimeout function is present but empty, potentially causing confusion.
The commented-out getCreditCardType function isn't utilized.
Potential Focus Issues:
Automatically focusing on the next input may lead to a poor user experience on mobile devices.
Validation Enhancements:
Currently, only client-side validation is minimal. Implementing more robust validation can enhance security and user experience.
Recommended Improvements:
Update Selectors to Match HTML:
Modify JavaScript to reference the new ids for inputs and display sections.
Remove or Implement Optional Code:
Either fully implement the getCreditCardType function or remove it if not needed.
Enhance Validation:
Implement more robust validation to handle different card types and formats.
Improve User Experience:
Consider conditional focusing or provide visual cues without forcing focus shifts.
Clean Up Unused Code:
Remove the empty setTimeout function unless intended for future use.
