Answer 1

我认为JS文件加载顺序错误。引导JS需要jQuery才能工作。

Answer 2

请确保您有顺序链接jQuery和引导JS。

<nav class="navbar navbar-inverse navbar-static-top" role="navigation"> 
       <div class="container"> 
      <div class="navbar-header"> 
      <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1"> 
      <span class="sr-only">Toggle navigation</span> 
      <span class="icon-bar"></span> 
      <span class="icon-bar"></span> 
      <span class="icon-bar"></span> 
      </button> 
     </div> 

     <!-- Collect the nav links, forms, and other content for toggling --> 
     <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1"> 
        <ul class="nav navbar-nav"> 
         <li><a href="#">Home</a></li> 
         <li><a href="#">Mission</a></li> 
         <li><a href="#">Services</a></li> 
         <li><a href="#">Staff</a></li> 
         <li><a href="#">Testimonials</a></li> 
        </ul> 
       </div> 
      </nav>
