jstl if 조건 판단 문자열 코드

 <c:if test="${netWorkInfo.networkType eq '   '}">

            <input type="radio" name="networkType" id="networkType" value="   " checked="checked"/>   

            <input type="radio" name="networkType" id="networkType" value="     "/>

            <input type="radio" name="networkType" id="networkType" value="     " checked="checked"/>     

            <input type="radio" name="networkType" id="networkType" value="4S"/>4S

        </c:if>

        <c:if test="${netWorkInfo.networkType eq '4S'}">

            <input type="radio" name="networkType" id="networkType" value="   "/>   

            <input type="radio" name="networkType" id="networkType" value="     "/>     

            <input type="radio" name="networkType" id="networkType" value="4S" checked="checked"/>4S

        </c:if>

설명:
String a="111";String b="111";< c:if test="${b eq a}">   eq 를 사용 하 는 것 이 같 습 니 다. 문자열 은 '' 를 사용 하여 구문 조건 을 ${} 에 판단 합 니 다.
