조건으로 required 되고 안되고 하기
본문
안녕하세요 항상 도움 받고 있습니다. 감사합니다.
만약 셀렉트에서 특정 값인 경우에
required 인 경우가 필수가 아니게 되려면 어떻게 해야 하나요?
코드는 아래와 같습니다.
매물 종류가 토지/임야로 셀렉트 된 경우에 아래 건축면적 required 값이 필수로 입력하지 않게 하려면 어떻게 해야 하나요?

$('#type_of_sale').on('change', function() {
if ($(this).val() == '토지/임야') {
$('#building_area_m2').prop('required', false);

} else {
