내 코드 :
<script type="text/javascript">
function ValidateSchool(form){
var cat_school = document.getElementsByName('school[]');
for (i = 0; i < cat_school.length; i++){
if (cat_school[i].checked == true){
return true;
}else{
alert('No item selected');
return false;
}
}
}
</script>

어떤 아이디어 나 제안? 감사. 내가 이해할 수있는 최소한 하나 개의 항목이 체크되어 있는지 여부를 확인하려면에서
