[JSP] JSP로 게시판 만들기[MODEL 1] - 12(답글달기)

Programming/JSP - 게시판만들기 2013. 1. 25. 16:40
이곳에서도 reply.jsp 와 reply_ok.jsp를 모두 수정해야합니다.

기존의 reply.jsp

    pageEncoding="EUC-KR"%>
<%@ page import="java.sql.*"%>  
<script language = "javascript">  // 자바 스크립트 시작

function replyCheck()
  {
   var form = document.replyform;
   
   if( !form.name.value )   // form 에 있는 name 값이 없을 때
   {
    alert( "이름을 적어주세요" ); // 경고창 띄움
    form.name.focus();   // form 에 있는 name 위치로 이동
    return;
   }
   
   if( !form.password.value )
   {
    alert( "비밀번호를 적어주세요" );
    form.password.focus();
    return;
   }
   
  if( !form.title.value )
   {
    alert( "제목을 적어주세요" );
    form.title.focus();
    return;
   }
 
  if( !form.memo.value )
   {
    alert( "내용을 적어주세요" );
    form.memo.focus();
    return;
   }
 
  form.submit();
  }
 </script>
