Bootstrap 4 模态不会在点击时打开

Question

我无法打开我的模式。我只尝试了在 Bootstrap 4 站点上找到的纯 HTML，然后使用了一些 Javascript。我真的无法弄清楚我做错了什么。任何帮助将不胜感激！

enter code here

<div class="col-sm-3 col-centered  boxes" id="box1">

  <button type="button" class="btn btn-primary" id="box1modal" data-toggle="modal" data-target="#exampleModal">

  </button>

  <!-- Modal -->
  <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">

    <div class="modal-dialog" role="document">

      <div class="modal-content">

        <div class="modal-header">

          <h5 class="modal-title" id="exampleModalLabel">Wedding Invites</h5>

          <button type="button" class="close" data-dismiss="modal" aria-label="Close">

            <span aria-hidden="true">&times;</span>

          </button>

        </div>

        <div class="modal-body">

          <img src="Wedding%20Invites.jpg">


        </div>

        <div class="modal-footer">

          <button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>

          <button type="button" class="btn btn-primary">Save changes</button>

        </div>

      </div>

    </div>

  </div>

</div>
 `enter code here`<script type="text/javascript">

enter code here $("#box1modal").click(function(event){
enter code here$('#myModal').modal('show'); enter code here)};

Answer 1

如果您使用 bootstrap，则无需额外的脚本。bootstrap 本身提供脚本来运行不同的动画和动作。我检查了你的代码。 错误在于行

   <button type="button" class="btn btn-primary" id="box1modal" data-toggle="modal" data-target="#exampleModal">

看到您已将数据目标设置为#exampleModal，而您的模态ID 为“myModal”。只需将上面的代码更改为

   <button type="button" class="btn btn-primary" id="box1modal" data-toggle="modal" data-target="#myModal">

而且它可以在没有任何其他脚本的情况下正常工作。 希望这会有所帮助...

Answer 2

您已将数据目标指定为 examplemodal，并将 div 的 id 指定为 mymodal。两者应该是一样的，这就是问题所在。

Answer 3

我测试你的代码，一切都很好，只是你必须确保

1) 添加引用 2）你的代码必须在 $(document).ready(function(){ ---- }
