[javascript]정규식 활용 회원가입 기능(아이디 중복확인, 요소 입력확인) [펌]

 

1. 목표


1. 개발환경

  > Spring Boot 2.1.7, JDK 8

2. JavaScript, jQuery, 정규식을 활용해 회원가입 기능 구현

 

  > 뷰 요소 : ID, 이름, 비밀번호, 비밀번호 확인, 이메일

 

  > 정규식 활용 뷰 요소 :

- ID : 영소문자, 영대문자, 숫자만 가능하게끔 설정. 공백 포함 불가.

 

- 이름 : 공백 포함 불가.

 

- 이메일 : 이메일 형식에 맞게끔 설정(aaa@bbbb.bbb)

 

2. 기능


1. ID 중복체크

  > ID 입력란에 키다운 이벤트가 발생하면 ajax 통신을 통해 중복된 아이디인지 판별

  > 중복되지 않은 아이디인 경우에만 회원가입 버튼 활성화

 

2. 입력요소 빈 칸 체크

  > ID, 이름, 비밀번호가 비어있는지 체크

  > 비어있지 않은 경우에만 회원가입 버튼 활성화

 

3. 소스코드
