我試圖在dropdown-menu隱藏引導程式時觸發一個函式，這是我嘗試過的代碼：
jQuery(document).ready(function($) {
$(".dropdown-menu").on("hidden.bs.collapse", function(e) {
console.log(e);
});
});<link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap/5.2.0/css/bootstrap.rtl.min.css" rel="stylesheet" />
<link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap/5.2.0/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap/5.2.0/js/bootstrap.bundle.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="btn-group dropup">
<button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
Dropup
</button>
<ul class="dropdown-menu">
<li><a class="dropdown-item" href="#">Menu item</a></li>
<li><a class="dropdown-item" href="#">Menu item</a></li>
<li><a class="dropdown-item" href="#">Menu item</a></li>
</ul>
</div>沒有任何東西被寫入控制臺，我做錯了什么？
謝謝！
uj5u.com熱心網友回復：
在 .dropdown-menu 的父元素上添加事件偵聽器。在你的情況下
.dropup你需要使用
hidden.bs.dropdown..collapse你用的是導航的
jQuery(document).ready(function($) {
$(".dropup").on("hidden.bs.dropdown", function(e) {
console.log(e);
});

<div class="btn-group dropup">
<button type="button" class="btn btn-secondary dropdown-toggle" data-bs-toggle="dropdown" aria-expanded="false">
Dropup
</button>
<ul class="dropdown-menu">
<li><a class="dropdown-item" href="#">Menu item</a></li>
<li><a class="dropdown-item" href="#">Menu item</a></li>
<li><a class="dropdown-item" href="#">Menu item</a></li>
