vue.js ToDoList 만들기 [컴포넌트 통신X] --1

 

-Todolist 제작

header, input, list, footer 네 가지의 컴포넌트로 나누어 제작

 

---

 

-기능 설명

input : list 입력, list없을 시 작성 안내 문구, 입력칸이 공백인데 등록 버튼 클릭 시 작성 안내 모달창 출력

list : input으로 받은 list 출력, 할일 목록 진행중/완료 체크 기능, 일정 삭제 기능

footer : list 전체 삭제

 

 

-현재 문제점

1. list 입력 시 바로 적용되지 않고 새로 고침 후 화면에 일정이 등록됨

2. list 삭제 버튼 클릭 시 바로 적용이 안되고 새로 고침 후 삭제 확인 됨

2. list 전체 삭제 버튼 클릭 시 바로 적용되지 않고 새로 고침 후 삭제 확인 됨

=> 각 컴포넌트간에 데이터 전달이 안돼서 갱신이 안됨

 

 

-해결 방법

전체 컴포넌트에서 하나의 데이터만 바라보게 변경

 

 

디자인 무시 부탁 ..
