JSTL -> JSP Standard Tag Library
JSTL 종류.
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%@ taglib prefix="fn" uri="http://java.sun.com/jsp/jstl/functions"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form"%>
실무에서 많이 사용하는 JSTL이다.
<%@ taglib prefix="daum" tagdir="/WEB-INF/tags/daum" %>
이런식으로 WEB-INF 밑에 외부파일을 태그 라이브러리로 사용하는경우도 많다.
fn 태그
#contains
<a href="${fn:contains(featuredTypeUri,'-mobile') ? '/sp' : ''}/pages/
${list.featuredUrl}" target="_blank">
#replace
<td>${fn:replace(fn:replace(list.displayListFlag,'Y','공개'),'N','비공개')}</td>
#substring
<td>${fn:substring(board.creationDate, 0, 4)}-${fn:substring(board.creationDate, 4, 6)}
-${fn:substring(board.creationDate, 6, 8)}</td>
#indexOf
<c:if test="${fn:indexOf(requestContext.httpHost, 'www.url.com') > -1 ||
fn:indexOf(requestContext.httpHost, '111.111.111.11') > -1}">
#length
<td rowspan="${fn:length(category.conditions)}">

<div class="input_wrap">
<c:set var="phone_arr" value="${fn:split(seller.phoneNumber, '-') }"/>

</div>
</td>
#contains
-문자열 포함여부 : Parameter(Target String , Matched String) Return -> true / false를 반환
#replace
-문자열 재정의 Parameter(Target String , Matched String, Change String) Return -> Change String
#substring
-문자열 자르기 Parameter(Target String , StartIndex , EndIndex)
#indexOf
-문자열 포함여부 : Parameter(Target String , Matched String) Return -> 일치하는 시작열 반환 / 미일치시 -1 반환
EX) ('ABCDE' , 'E') -> 4반환. index는 0부터 시작.
#length
-문자열 길이 : 길이반환
#split
-문자열 나누기 : (Target String ,Matched String)
-Return -> Matched String을 기준으로 배열반환
