我正在构建一个响应不同平台/设备的 bootstrap4 导航栏。导航栏不响应移动屏幕尺寸。下面是模板

<nav class="navbar navbar-inverse navbar-fixed-top">
<div class="container-fluid">
<div class="navbar-header">
<button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#myNavbar" aria-controls="myNavbar" aria-expanded="false" aria-label="Toggle navigation">
 <span class="icon-bar"></span>
 <span class="icon-bar"></span>
 </button>
 </div>
 <a class="navbar-brand" href="#">World Visuo</a>


 <div class="collapse navbar-collapse" id="myNavbar"> 
 <ul class="nav navbar-nav navbar-right" >
 <li class="active"><a href="#">Community</a></li>
 <li class="popup1_open data-toggle="modal" data-target="#myModal"><a href="#">Sign Up</a></li>
 <li class="popup2_open"><a href="#">Login</a></li>
 </ul>
 </div>

<!--Modals Starts-->

<div class="modal-content">

<div class="modal-header">

<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p>Some text in the modal.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div> <!--modal ends here-->

 </div>

 </nav>

 <!-- section 1 starts here-->
 <div class="container-fluid"></div><!-- section 1 ends -->

 <script src="https://code.jquery.com/jquery-3.3.1.slim.min.js">               </script>

我希望通过按钮切换“社区、注册、登录”，但只会隐藏内容但不会打开。我做错了什么？

【解决方案1】：

你需要加载你没有做的引导 javascript。此外，您正在使用 bootstrap 3，它不适用于 jquery slim，因此您需要在 jquery 上使用完整版本。我相信您需要使用 jquery 2，所以我加载了它。我还使用了最新版本的 bootstrap 3，即 3.7。您还需要将导航栏品牌放在导航栏标题中。这里所说的只是您代码的更新版本。
