- 회원 등급 변경(등급변경 버튼을 클릭해서 변경)
<button class="btn bc5 changeLevel">등급변경</button>버튼 관련 스크립트(현재등급과 회원번호를 서블릿에 보내주기위함)
<script>
$(".changeLevel").on("click", function(){
//클릭한 버튼을 기준으로 해당 회원의 번호
const memberNo = $(this).parent().parent().children().eq(1).text();
//클릭한 버튼을 기준으로 선택한 등급
const memberLevel = $(this).parent().prev().children().val();
//회원등급에 필요한 정보수집은 끝 -> 회원번호, 선택한등급
//-> 서버에 update요청을 해줘야함(1. 폼태그로 요청 / 2. a태그로 요청)
//-> 지금은 form도 a태그도 아닌 javascript(폼/a태그를 만들어서 요청이 가능하긴함)
//-> a태그 요청 <a href="/서블릿주소?key1=value1&key2=value2"> -> 이역할을 해주는 javascript함수가 잇음
// location.href
location.href = "/changeLevel.do?memberNo="+memberNo+"&memberLevel="+memberLevel;
