Question

当平板电脑/移动视图中的菜单崩溃时，我无法启动引导下拉菜单或按钮。这是我的导航html：

<nav class="navbar navbar-default navbar-fixed-top">
        <div class="container">
          <div class="navbar-header">
            <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#navbar" aria-expanded="false" aria-controls="navbar">
              <span class="sr-only">Toggle navigation</span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
              <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="#"><img alt="brand" height="50" width="100" src="media/expend-logo.svg"></a>
          </div>
          <div id="navbar" class="navbar-collapse collapse">
            <ul class="nav navbar-nav navbar-right">
              <li class="active"><a href="#">Home</a></li>
              <li><a href="#about">About</a></li>
              <li><a href="#contact">Contact</a></li>
              <li class="dropdown">
                <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
                <ul class="dropdown-menu">
                  <li><a href="#">Action</a></li>
                  <li><a href="#">Another action</a></li>
                  <li><a href="#">Something else here</a></li>
                  <li role="separator" class="divider"></li>
                  <li class="dropdown-header">Nav header</li>
                  <li><a href="#">Separated link</a></li>
                  <li><a href="#">One more separated link</a></li>
                </ul>
              </li>
            </ul>
          </div><!--/.nav-collapse -->
        </div>
      </nav>

这些是脚本：

<script type="text/javascript" src="Scripts/jquery-2.1.1.min.js"></script>
<script type="text/javascript" src="Scripts/bootstrap.min.js"></script>
<script>
     $(document).ready(function () {
     $('.dropdown-toggle').dropdown();
     });
</script>

我做错了什么？提前谢谢！

                            <li><a href="link1"><p class="text-center"> Link page</p></a> </li>
                            <li role="separator" class="divider"></li>
                            <li><a href="link2"><p class="text-center"> Linkpage 2</p></a></li>
                            <li role="separator" class="divider"></li>
                            <li><a href="link3"><p class="text-center"> Link page 3</p></a></li>
                        </ul>
