模式上的关闭按钮不起作用......我做错了什么？

Question

我制作了一个模式，当单击它时会弹出一个图像，但由于某种原因我无法让关闭按钮工作。有人可以检查我的代码，看看我哪里出错了吗？或者给我一些建议...谢谢！

<div id = "myModal" class = "modal">
        <div class = "modal-content">
            <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
            <!-- Modal Content (The Image) -->
            <img class="modal-content" id="mimg">

            <!-- Modal Caption (Image Text) -->
            <div id="caption"></div>
        </div>
    </div>
    <img id="myImg" src="http://i0.kym-cdn.com/photos/images/newsfeed/001/023/007/f29.png" alt="Trolltunga, Norway" width="300" height="200">

Answer 1

简单的例子，如果你使用 bootstrap，请确保使用 bootstrap 方式。

另外，请确保引用正确。

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

#myImg {
  width: 100%;
  height: auto;
}

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

<button type="button" class="btn" data-toggle="modal" data-target="#myModal">Open Modal</button>

<div id="myModal" class="modal">
  <div class="modal-dialog">
    <div class="modal-content">
      <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
      <!-- Modal Content (The Image) -->
      <img id="myImg" src="https://pbs.twimg.com/media/BU27_rrCYAAckFP.jpg" alt="Trolltunga, Norway">
      <!-- Modal Caption (Image Text) -->
      <div id="caption">Modal Caption (Image Text)</div>
    </div>
  </div>
</div>

您的代码不完整。尝试添加如下

<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>

<!-- Modal -->
<div id="myModal" class="modal fade" role="dialog">
  <div class="modal-dialog">

    <!-- Modal content-->
    <div class="modal-content">
      <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal">&times;</button>
        <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>
