Question

我正在尝试一个简单的bootstrap navbar。但是，我的data-toggle无效。

这是HTML：

<body>
    <nav class="navbar navbar-default navbar-inverse navbar-fixed-top">
        <div class="navbar-header">
            <button type="button" class="navbar-toggle" data-target=".navbar-collapse" data-toggle="collapse">
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
        </div> 
        <div class="navbar-collapse collapse">
            <ul class="nav navbar-nav">
                <li class="active"><a href="#">Home</a></li>
                <li><a href="#">Meet the Team</a></li>
                <li><a href="#">Get Involved</a></li>
                <li><a href="#">Contact Us</a></li>
            </ul>
        </div>
    </nav>
</body>

Answer 1

<nav class="navbar navbar-toggleable-md navbar-inverse navbar-fixed-top">
  <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbar-collapse" aria-controls="navbar-collapse"
    aria-expanded="false" aria-label="Toggle navigation">
    <span class="navbar-toggler-icon"></span>
  </button>
  <div class="collapse navbar-collapse" id="navbar-collapse">
    <ul class="navbar-nav mr-auto mt-2 mt-lg-0">
      <li><a href="#">Meet the Team</a></li>
      <li><a href="#">Meet the Team</a></li>
      <li><a href="#">Get Involved</a></li>
      <li><a href="#">Contact Us</a></li>
    </ul>
  </div>
</nav>

问题是data-target=".navbar-collapse"。

点只属于类。您必须使用＃和可折叠部分<div class="collapse navbar-collapse" id="navbar-collapse">

的ID
