Bootstrap导航栏切换按钮不起作用

当页面缩小到平板电脑/手机大小时，显示切换按钮，但不起作用。下面是HTMLBootstrap导航栏切换按钮不起作用

<nav class="navbar navbar-inverse navbar-fixed-top"> 
 
    <div class="container"> 
 
    <div class="navbar-header"> 
 
     <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-nav-demo" aria-expanded="false"> 
 
     <span class="sr-only">Toggle navigation</span> 
 
     <span class="icon-bar"></span> 
 
     <span class="icon-bar"></span> 
 
     <span class="icon-bar"></span> 
 
     </button> 
 
     <a href="#" class="navbar-brand"><span class="glyphicon glyphicon-picture" aria-hidden="true"></span> IMGS</a> 
 
    </div> 
 
    <div class="collapse navbar-collapse" id="bs-nav-demo"> 
 
     <ul class="nav navbar-nav"> 
 
     <li><a href="#">About</a></li> 
 
     <li><a href="#">Contact</a></li> 
 
     </ul> 
 
     <ul class="nav navbar-nav navbar-right"> 
 
     <li><a href="#">Sign Up</a></li> 
 
     <li><a href="#">Login</a></li> 
 
     </ul> 
 
    </div> 
 
    </div> 
 
</nav> 
 

 
.... 
 
.... 
 

 

 
<script type="text/javascript" href="https://code.jquery.com/jquery-2.2.1.js"></script> 
 
<script type="text/javascript" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>

必要的JavaScript链接。

所以我找到了问题;这是非常轻微的。 href属性应该替换为脚本标签上的src属性。崇高文本的选项卡按脚本默认为href。

呼叫bootstrap.css为好。这里我只是从我的本地文件中调用它

<link href="http://freelancezonebd.com/sb-web/3/css/bootstrap.css" rel="stylesheet"/>

您可以从CDN调用它。也可以调用js文件使用“src”而不是“href”。谢谢。

    background-color: transparent; 
 
    background-image: none; 
 
    border: 1px solid transparent; 
 
    border-radius: 4px; 
 
    float: right; 
 
    left: -300px; 
 
}

<link href="http://freelancezonebd.com/sb-web/3/css/bootstrap.css" rel="stylesheet"/> 
 
<nav class="navbar navbar-inverse navbar-fixed-top">

\t \t \t \t <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-nav-demo" aria-expanded="false">
