HTML

<select id='season' name='season'>
    <option value=''>All</option>
    <option value='0'>Spring</option>
    <option value='1'>Summer</option>
    <option value='2'>Fall</option>
    <option value='3'>Winter</option>
</select>

 

[방법1] 삼항 연산자

<select id='season' name='season'>
    <option value=''>All</option>
    <option value='0' ${season == '0' ? 'selected="selected"' : ''}>Spring</option>
    <option value='1' ${season == '1' ? 'selected="selected"' : ''}>Summer</option>
    <option value='2' ${season == '2' ? 'selected="selected"' : ''}>Fall</option>
    <option value='3' ${season == '3' ? 'selected="selected"' : ''}>Winter</option>
</select>

 

[방법2] 삼항 연산자 + JSTL

컨트롤러에서 넘어온 객체가 리스트인 경우

<select id='season' name='season'>
    <option value=''>All</option>
    <c:forEach items='${resultList}' var='list'>
        <option value='${list.listNo}' ${list.listNo == '1' ? 'selected="selected"' : ''}>${list.listName}</option>
    </c:forEach>
</select>

 

[방법3] JSTL

<select id='season' name='season'>
    <option value=''>All</option>
    <c:forEach items='${resultList}' var='list'>
        <option value='${list.listNo}' <c:if test='${list.listNo == "1"}'>selected='selected'</c:if>>${list.listName}</option>
    </c:forEach>
</select>
