Bootstrap下拉菜单不起作用

css

我无法正常使用下拉菜单。我可以使导航栏完美显示，但是当我单击“
Dropdown”（二者之一）时，它不会显示下拉菜单。我曾尝试查看有关此问题的其他文章，但没有什么能解决每个人的问题。我直接从bootstrap网站复制了源代码，但似乎无法在我的机器上使用它。谁有想法？我盯着它看了一个小时，似乎无法弄清楚问题出在哪里。

<head>
<script src="resource/js/jquery-1.11.0.js"></script>
<script src="resources/js/bootstrap.js"></script>

<script type="text/javascript">
$(document).ready(function() {
    $('dropdown-toggle').dropdown()
});
</script>
</head>
<body>
<nav class="navbar navbar-default" role="navigation">
  <div class="container-fluid">
    <!-- Brand and toggle get grouped for better mobile display -->
    <div class="navbar-header">
      <button type="button" class="navbar-toggle" 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>
  <a class="navbar-brand" href="#">Brand</a>
</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 class="active"><a href="#">Link</a></li>
    <li><a href="#">Link</a></li>
    <li class="dropdown">
      <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></a>
      <ul class="dropdown-menu" role="menu">
        <li><a href="#">Action</a></li>
        <li><a href="#">Another action</a></li>
        <li><a href="#">Something else here</a></li>
        <li class="divider"></li>
        <li><a href="#">Separated link</a></li>
        <li class="divider"></li>
        <li><a href="#">One more separated link</a></li>
      </ul>
    </li>
  </ul>
  <form class="navbar-form navbar-left" >
    <div class="form-group">
      <input type="text" class="form-control" placeholder="Search">
    </div>
    <button type="submit" class="btn btn-default">Submit</button>
  </form>
  <ul class="nav navbar-nav navbar-right">
    <li><a href="#">Link</a></li>
    <li class="dropdown">
      <a href="#" class="dropdown-toggle" data-toggle="dropdown">Dropdown <b class="caret"></b></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 class="divider"></li>
        <li><a href="#">Separated link</a></li>
      </ul>
    </li>
  </ul>
</div><!-- /.navbar-collapse -->

也许尝试

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script src="//netdna.bootstrapcdn.com/bootstrap/3.1.1/js/bootstrap.min.js"></script>
<link rel="stylesheet" type="text/css" href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css">

看看是否行得通。
