次のフォーム検証スクリプトを作成しましたが、「アイテムが選択されていません」というたびに機能しません。この問題を解決するために私を助けてください。
私のコード:
<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>
<form name="frm" method="post" action="#" onsubmit="return ValidateSchool(this)">
