html - 按下按钮时不弹出 Boostrap 模态

问题描述

我试图弹出一个模式，但是当我按下按钮时没有任何反应。这是迄今为止的HTML代码-

<!DOCTYPE html>

    <!-- Button trigger modal -->
    <button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalScrollable">
      Launch demo modal
    </button>

    <!-- Modal -->
    <div class="modal fade" id="exampleModalScrollable" tabindex="-1" role="dialog" aria-labelledby="exampleModalScrollableTitle" aria-hidden="true">
      <div class="modal-dialog modal-dialog-scrollable" role="document">
        <div class="modal-content">
          <div class="modal-header">
            <h5 class="modal-title" id="exampleModalScrollableTitle">Modal title</h5>
            <button type="button" class="close" data-dismiss="modal" aria-label="Close">
              <span aria-hidden="true">&times;</span>
            </button>
          </div>
          <div class="modal-body">
            <p>
                Well, hello there!
            </p>
          </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>

当我打开页面时，左上角会出现一个按钮。按下它后，它会突出显示，但什么也没有发生。您知道为什么会发生这种情况，以及如何解决吗？

解决方案

You have used bootstrap 4 code instead of bootstrap 5 code, either make all your modals the way bootstrap 5 does it, and you can read it here: https://getbootstrap.com/docs/5.0/components/modal/

or just change bootstrap versions to bootstrap 4

The difference is mostly that in bootstrap 5 you use "data-bs" + something in your attributes instead of just "data-"
