我是 bootstrap 模式的新手。我从 文档 中复制并粘贴了现场演示，但它似乎不起作用。 这里 是我的小提琴。任何帮助都将不胜感激。谢谢。我的代码如下。 

<head>
  <!-- Latest compiled and minified CSS -->
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
  <!-- Latest compiled and minified JavaScript -->
 <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
</head>

 <!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">
  Launch demo modal
</button>

<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
  <div class="modal-dialog" role="document">
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title" id="myModalLabel">Modal title</h4>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

为了充分利用 bootstrap 的魔力，它需要 jQuery，因此在 bootstrap js 文件上方的 head 标签中添加一个链接到 jQuery 的脚本标签，如下所示：

https://code.jquery.com/jquery-2.1.4.min.js

您可以在控制台中看到要求输入 jQuery 的错误：

您需要在 Bootstrap JavaScript 之前包含 jQuery。 

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
