B(keyup.enter)
C(keydown)

    (keyup.enter) triggers submitForm() only when Enter is released, which is the recommended approach.
  3. Final Answer:

    (keyup.enter) -> Option B
  4. Quick Check:

    Use (keyup.enter) to detect Enter key [OK]
Quick Trick: Use (keyup.enter) to trigger on Enter key press [OK]
Common Mistakes:
  • Using (keydown) without key filter triggers on all keys
  • Using (keyup) triggers on all keys, not just Enter
  • Using deprecated (keypress.enter) event
