當我更改瀏覽器大小時，Bootstrap4導航欄菜單不起作用

我正在使用CDN中的bootstrap4導航欄，當我更改瀏覽器分辨率時，導航欄菜單不顯示選項，我看不到錯誤在哪裏，任何暗示都是很好的。這裏是我的代碼：當我更改瀏覽器大小時，Bootstrap4導航欄菜單不起作用

您需要指定正確的目標崩潰。它應該是data-target="#navbarNav"，因爲id=navbarNav在navbar-collapse。

<button class="navbar-toggler navbar-toggler-right" type="button" data-toggle="collapse" data-target="#navbarNav" aria-controls="#navbarNav" aria-expanded="false" aria-label="Toggle navigation"> 
     <span class="navbar-toggler-icon"></span> 
</button>

是的，解決辦法是添加jQuery的，改變數據目標= 「＃navbarNav」，因爲ID = navbarNav在導航欄崩潰，它是由@ZimSystem說 –
