일부 if 문 안에 Case 문이 있는데 if 문 안에서 Case 문을 실행한 후 루프가 종료됩니다. Case 문 다음에 배열의 다음 값으로 이동해야 합니다. 배열의 첫 번째 값은 if 문을 전달한 후 케이스를 전달한 후 배열의 다른 값으로 반복하는 대신 스크립트가 완료됩니다.

답변1
break해당 문을 추가하여 종료 yes되므로 for-loop나머지 배열 테스트를 완료할 수 없습니다. break"is" 케이스 문에서 이를 제거하세요 .
몇 가지 수정 사항을 적용하여 코드를 테스트한 결과 예상한 결과를 얻었습니다.

답변2
명확한지는 모르겠지만 break 및 종료를 사용하면 루프가 중단될 수 있습니다.
