100. Validating the Form

npm create vue@latest

  1. 폼 전체 검증:

    • 사용자가 제출을 시도할 때 전체 폼을 검증.
    • 입력 필드에 대한 강제 검증 필요.

  2. 검증 처리 방식:

    • validate는 사용자가 입력 필드와 상호작용할 때까지 기다림.
    • 사용자가 자동으로 검증을 트리거하지 않으면 강제 검증 수행.

  3. 이벤트 리스너 추가:

    • 폼 컴포넌트에 submit 이벤트 리스너 추가.
    • validate는 기본 submit 이벤트의 변형된 버전을 생성.

  4. 제출 이벤트의 작동 방식:

    • 필드 컴포넌트에 대한 강제 검증 수행.
    • 유효하지 않은 입력이 있으면 표현식 실행 안 함.
    • 페이지 새로고침 방지.

  5. register 함수:

    • 폼이 유효할 때 register 함수 실행.
    • 유효하지 않은 입력이 있으면 register 함수 호출되지 않음.
    • register 함수에서 폼의 값 처리.

  6. 데이터 추적 시스템:

    • v-model 지시문 사용하지 않고, validate 라이브러리가 폼 데이터 추적.

  7. 테스트 및 검증:

    • 브라우저에서 페이지 새로고침 후 테스트.
    • 모든 필드에 대한 오류를 콘솔에서 확인.
    • 유효한 값으로 폼을 채우고 제출 시, 콘솔에 값 로그 확인.

  8. 추가 최적화:

    • 데이터 제출 전 추가적인 최적화 방안 고려.
