我尝试在 bootstrap 中创建一个下拉菜单,但它不起作用! 我在 w3schools 中尝试了很多样本​​,但没有一个有效:(

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>

<!-- My Code -->
<div class="container">
<h2>Dropdowns</h2>
<p>The .dropdown class is used to indicate a dropdown menu.</p>
<p>Use the .dropdown-menu class to actually build the dropdown menu.</p>
<p>To open the dropdown menu, use a button or a link with a class of .dropdown-toggle and data-toggle="dropdown".</p>
<div class="dropdown">
<button class="btn btn-primary dropdown-toggle" type="button" data-toggle="dropdown">Dropdown Example
<span class="caret"></span></button>
<ul class="dropdown-menu">
<li><a href="#">HTML</a></li>
<li><a href="#">CSS</a></li>
<li><a href="#">JavaScript</a></li>
</ul>
</div>
</div>

最佳答案

尝试完成标记。在这里工作正常。
