导航栏切换在展开后不会折叠

Question

嗨，我有一个导航栏，一旦展开就不会折叠。

如果有人可以看看我的代码并给我一些建议，那将对我有很大帮助。

  <nav class="navbar navbar-expand-lg navbar-light bg-light border-bottom">
    <button class="btn btn-primary" id="menu-toggle">Show Rooms</button>

    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
      <span class="navbar-toggler-icon"></span>
    </button>

    <div class="collapse navbar-collapse" id="navbarSupportedContent">
      <ul class="navbar-nav ml-auto mt-2 mt-lg-0">
        <li class="nav-item active">
          {% if session['username'] %}
          <a id='change_username_btn' class="nav-link" href="#">{{ session['username'] }} <span class="sr-only">(current)</span></a>
        </li>
        <li class="nav-item">
          <a class="nav-link" href= "{{ url_for('logout') }}">Log Out</a>
        </li>

          {% else %}
          <li class="nav-item active">
              <a data-toggle="modal" data-target="#exampleModalCenter" id='change_username_btn' class="nav-link" href="#">Click Here to Enter Username<span class="sr-only">(current)</span></a>
          </li>

          {% endif %}
      </ul>
    </div>
  </nav>

您的代码有一个简单的问题。 您正在尝试折叠响应式导航栏，因此它不会很好地折叠。 您必须删除navbar-collapse类以防止响应。

试试这个（我没有改变你的设计）：

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script> <link href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css" rel="stylesheet"/> <script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/js/bootstrap.min.js"></script> <!DOCTYPE html> <html lang="en"> <head> <title>Bootstrap Example</title> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> </head> <body> <nav class="navbar navbar-expand-lg navbar-light bg-light border-bottom"> <button class="btn btn-primary" id="menu-toggle">Show Rooms</button> <button type="button" class="navbar-toggler collapsed" data-toggle="collapse" data-target="#navbarSupportedContent" aria-expanded="false" aria-controls="navbar"> <span class="navbar-toggler-icon"></span> </button> <div class="collapse" id="navbarSupportedContent"> <ul class="navbar-nav"> <li class="nav-item"> <a id='change_username_btn' class="nav-link" href="#">Name <span class="sr-only">(current)</span></a> </li> <li class="nav-item"> <a class="nav-link" href= "{{ url_for('logout') }}">Log Out</a> </li> </ul> </div> </nav> </body> </html>
