Question

我正在尝试使用其网站上的代码使用引导模式窗口。不幸的是，当我使用窗口时，由于某种原因，窗口无法正常工作。

我用过这个样本：

<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-sm">Small modal</button>

<div class="modal fade bs-example-modal-sm" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel">
    <div class="modal-dialog modal-sm" role="document">
        <div class="modal-content">
            ...SOME MORE CONTENT HERE...
        </div>
    </div>
</div>

我得到的只是褪色的屏幕，模态本身位于布局之上，而在浏览器窗口中看不到。这可能是什么问题？

您的代码是正确的，您只需要添加内容

＆＃13;

<!DOCTYPE html>
<html lang="en">
<head>
  <title>Bootstrap Example</title>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width, initial-scale=1">
  <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>

<div class="container">
  
  <!-- your button -->
  <button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-sm">Small modal</button>
  
  <!-- your modal -->
  <div class="modal fade bs-example-modal-sm" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel">
  <div class="modal-dialog modal-sm" role="document">
    <div class="modal-content">
      <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">&times;</button>
          
          <!-- I have added content here -->
          <h4 class="modal-title">Modal Header</h4>
        </div>
        <div class="modal-body">
          <p>Some text in the modal.</p>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
    </div>
  </div>
</div>
  
  
  

</div>

</body>
