如何使用bootstrap 5在没有jQuery的情况下编写JavaScript代码？

<script src="path/to/bootstrap.min.js"></script>

document.querySelector('#myButton').addEventListener('click', function() {
  // 在这里编写点击按钮后的操作
});

<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#myModal">
  打开模态框
</button>

<div class="modal fade" id="myModal" 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">模态框标题</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        模态框内容
      </div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">关闭</button>
        <button type="button" class="btn btn-primary">保存</button>
      </div>
    </div>
  </div>
</div>
