【问题描述】：
我已经按照导航栏中的汉堡包的逐步实施过程进行了操作。然而，在调整窗口大小时，导航栏会折叠，但点击它时不会打开。
请参考以下示例代码。我正在使用 bootstrap4 和 angular 6 版本。
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.3.1/js/bootstrap.min.js"></script>
<nav class="navbarc navbar-expand-lg navbar-dark shadow-sm p-3 mb-5 rounded navbar-fixed-top" style="padding: 0.5rem !important;
margin-bottom: .5rem !important; border-radius: 4px;
padding: 05px;">
<button class="navbar-toggler collapsed" type="button" data-toggle="collapse" data-target="#navbarNavDropdown" aria-controls="navbarNavDropdown" aria-expanded="false" aria-label="Toggle navigation">
<span class="navbar-toggler-icon"></span>
<span class="icon-bar"></span>
</button>
<div class="collapse navbar-collapse" id="navbarNavDropdown">
<ul class="navbar-nav mr-auto">
<li class="nav-item">
<a class="nav-links" style="font-size: 16px;" routerLink="">Special Discount <span class="sr-only">(current)</span></a>
</li>
<li class="nav-item">
<a class="nav-links" style="font-size: 16px;" routerLink="Products">Products on Discount</a>
</li>
</ul>
</div>
</nav>

我希望汉堡在点击事件时显示导航栏内容。 请帮助我了解我哪里出错了。 这方面的任何线索都会有所帮助..
【问题讨论】：
-
你在哪里添加那些
script元素？ Angular 从模板中剥离了这些元素。您应该在脚本数组中的angular.json文件中添加这两个 URL。 -
你能重现这个问题吗，这对我来说很好：codesandbox.io/s/youthful-dew-jy62k
-
@David ，引用已经存在于 angular.json 的脚本数组中。请参考以下snipet.-----"scripts": [ "./node_modules/jquery/dist/jquery.min.js", "./node_modules/popper.js/dist/popper.min.js ", "./node_modules/popper.js/dist/umd/popper.min.js", "./node_modules/bootstrap/dist/js/bootstrap.min.js" ], "es5BrowserSupport": true
-
@Cereal，我不明白，为什么汉堡包在“codesandbox”中运行良好而不在我的项目中运行良好？？
-
@user3794867 它工作正常，因为他直接在 HTML 文件中导入了依赖项。如果您最终也这样做，它可能也会起作用，但是可能有一些警告，因为它不是在您的 Angular 应用程序中包含文件的推荐方式。
