Question

msgbox が常に true に戻るのはなぜですか??

<script type="text/javascript">
function deletesubj(x){
    var conf = confirm("Are you sure you want to delete this subject?"){
         return true;
    }
    else{
     return false;
}
}</script>

Answer 1

次の後に状態を確認します。

var conf = confirm("Are you sure you want to delete this subject?")
if (conf) {
    return true;
} else {
    return false;
}
