我正在学习 Angular 和 Bootstrap。我有一些由 Yeoman 生成的代码，我的导航栏中的正常链接工作正常。但是，下拉元素不起作用(下拉菜单显示在导航栏中，但在单击时不会展开)。如您所见，我已将导航栏代码放入 View 本身。
有趣的是，当导航条码位于容器(例如 index.html)中时，它实际上会起作用。
我的问题是为什么我的导航栏代码在容器中正常工作的 View 中没有按预期工作？
这是我在 View 中的导航栏代码，导航栏下拉菜单不起作用(重要的是要注意其他导航栏元素似乎工作正常):

这是 Yoeman 为我的容器 (index.html) 生成的代码。导航条码应该和上面一样。

为了进行测试，我使用的是 Chrome，但我没有看到任何来自控制台的错误。我正在使用 Bootstrap 3。
感谢您的帮助。
问候， 盖杰
最佳答案
您可以尝试加强 dropdown-toggle 和 dropdown-menu 之间的关系。我认为 jQuery 首先寻找 data-parent，然后 href 来行动。向菜单添加一个 id 并从切换中指向它
<a data-parent="#messages-menu" href="#messages-menu" data-toggle="dropdown" class="dropdown-toggle">Messages <b class="caret"></b></a>
<ul id="messages-menu" class="dropdown-menu">
我只会使用 href(因为正如他们所说，每个 anchor 都应该始终有一个 href)
关于css - 导航栏中的下拉菜单不适用于 Bootstrap 和 Angular，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/23796174/
