これは、選択ボックスのコードです！
こんにちはカルロ、コードの別の部分は、矛盾です。 if（！$（event.target）.closest（ '＃browse-btn'）。length && ！$（event.target）.is（私は今、 '＃browse-btn'））{ if（$（ '＃browse-content'）が（ "：visible"））{ $（ '＃browse-content'）。hide（）; } } @ $ label.on（ 'クリック'、（E）=> リターン場合と }）@isDropOpen（）または@isDisabled（） e.stopPropagation（） @showDrop（） $（ 'HTML'） .one（ 'click'、（）=> @closeDrop（） ） ） – stef67
