[jsp와 servlet] 익명 방명록 만들기 ⑦ 글 번호 클릭하여 상세 보기

 

①① list jsp 에서 작성 해 놓은 코드를 이용하여 번호를 클릭하면 "/guset/detail" servlet 을 구동 할 수 있게 해 준다 

<tr><td><a href = "/webApp3/guest/detail?num=${vo.num }" onclick = "a()"> ${vo.num }</td>

 

 

doGet 에는 번호 클릭 후 상세 페이지로 이동하게 하고 상세페이지를 눌렀다면 cnt 가 1 증가하게 만들어 준다. 

doPost 에는 클라이언트가 내용 수정 후 수정 버튼을 눌렀을 때 수정이 가능 하도록 구현 해준다
