我發現arial-expanded 的屬性有時候會出現錯誤，即使下拉選單已經關閉，檢查此屬性卻仍是true。 <script> function check(){ alert("1=" + $("#1").attr("aria-expanded") + " 2=" + $("#2").attr("aria-expanded")); } </script> </head> <body onclick="check()"> <div class="dropdown btn-group-vertical" id="p1"> <button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown" aria-expanded="false" id="1" data-parent="#p1" aria-haspopup="true"> Dropdown button1 </button> <div class="dropdown-menu"> <div class="dropdown-header">Dropdown header 1</div> <a class="dropdown-item" href="#">Link 1</a> <a class="dropdown-item" href="#">Link 2</a> <div class="dropdown-divider"></div> <a class="dropdown-item" href="#">Link 3</a> </div> <button type="button" class="btn btn-primary dropdown-toggle" data-toggle="dropdown" aria-expanded="false" id="2" data-parent="#p1" aria-haspopup="true"> Dropdown button2 </button> <div class="dropdown-menu"> <div class="dropdown-header">Dropdown header 2</div> <a class="dropdown-item" href="#">Link 1</a> <a class="dropdown-item" href="#">Link 2</a> <div class="dropdown-divider"></div> <a class="dropdown-item" href="#">Link 3</a> </div>
