Bootstrap5 Modal Uncaught TypeError：在未实现接口 Element 的对象上调用“querySelector”

Question

我想使用模态，就像在文档中一样，我以这种方式尝试

<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#staticBackdrop">
  Launch static backdrop modal
</button>

<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        ...
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>

单击按钮时，我收到此错误“未捕获类型错误：在未实现接口元素的对象上调用‘querySelector’”

我做错了什么？

data-bs-target并且您的模态id应该相同，更改data-bs-target值应该#exampleModal可以解决您的问题。
