模态正文不会显示

Question

这些讨厌的模态再次出现。我可以让我的模态弹出，但由于一些奇怪的原因，它的正文中的文字并没有显示出来。这是怎么回事？这是模式：

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

    <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>Modal text.</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>

  </div>
</div>

Answer 1

也许这是你正在使用的Bootstrap的版本？

我刚刚将代码换成Codepen上使用Bootstrap 4.0.0的现有对话框，它可以工作：

<!-- basic modal -->
<!-- <div class="modal fade" id="basicModal" tabindex="-1" role="dialog" aria-labelledby="basicModal" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h4 class="modal-title" id="myModalLabel">Basic Modal</h4>
        <button type="button" class="close" data-dismiss="modal" aria-label="Close">
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">
        <h3>Modal Body</h3>
      </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> -->

<div id="basicModal" class="modal fade" role="dialog">
  <div class="modal-dialog">

    <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>Modal text.</p>
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
      </div>
    </div>

  </div>
