숙제 완성 후 궁금한 점이 있어서 문의합니다.
응원 남기기(POST): 정보 입력 후 '응원 남기기' 버튼클릭 시 주문목록에 추가
이 부분에서 공란인 상태에 '응원 남기기'를 눌러도 공란으로 된 항목이 저장이 되어서, 이걸 공란일 때 '응원 남기기'를 누르면 mongodb에 저장되지 않고
'닉네임을 입력해 주세요' 또는 '코멘트를 입력해 주세요' 라는 alert가 뜨게 해주려고 하는데...if를 사용해서 시도해보고 있는데 문구 알람도 안뜨고, mongodb에 저장도 안되고, 기존에 저장된 응원 목록 불러오기도 안되네요...
뭐가 문제일까요?
