Bootstrap 模式未按预期工作

Question

我已将 bootstrap 模态添加到我的网站，但它不起作用。有人帮我修一下。谢谢

  <button type="button" class="btn btn-info btn-lg">Update</button>

  <!-- Modal -->
  <div class="modal fade" id="myupdate" role="dialog">
    <div class="modal-dialog modal-sm">
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">&times;</button>
          <h4 class="modal-title">New Update </h4>
        </div>
        <div class="modal-body">
          <p>This is a small modal.</p>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        </div>
      </div>
    </div>
  </div>
</div>

Answer 1

缺少您的数据切换和目标

<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myupdate">Open Small Modal</button>

Answer 2

您需要将 data-target 设置为您的 modal 的目标 id 并将 data-toggle = "modal" 设置为您要在其上激活模态的 button

<button type="button" data-target="#myupdate" data-toggle="modal" class="btn btn-info btn-lg">Update</button>

  <!-- Modal -->
  <div class="modal fade" id="myupdate" role="dialog">
    <div class="modal-dialog modal-sm">
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">&times;</button>
          <h4 class="modal-title">New Update </h4>
        </div>
        <div class="modal-body">
          <p>This is a small modal.</p>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
        </div>
      </div>
    </div>
  </div>
