Bootstrap 5 - 模态不显示

Question

我正在尝试在使用以下代码点击图像时打开模式：

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

这是来自 Bootstrap Modal Doc 的原始代码但是还是让它工作了，我点击了按钮，但没有任何反应

可能是您遗漏了一些 bootstrap 依赖项。

这是完整的工作代码演示：

<!doctype html>
<html lang="en">

    <head>
        <!-- Required meta tags -->
        <meta charset="utf-8">
        <meta name="viewport" content="width=device-width, initial-scale=1">

        <!-- Bootstrap CSS -->

    </head>

    <body>
    
        <!-- Bootstrap Bundle with Popper -->

        <script src="https://cdn.jsdelivr.net/npm/bootstrap@5.0.1/dist/js/bootstrap.bundle.min.js" integrity="sha384-gtEjrD/SeCtmISkJkNUaaKMoLD0//ElJ19smozuHV6z3Iehds+3Ulb9Bn9Plx0x4" crossorigin="anonymous"></script>  

        <!-- Dialog demo -->  
                
        <button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModalLive">
            Launch demo modal
        </button>

        <div class="modal fade" id="exampleModalLive" tabindex="-1" aria-labelledby="exampleModalLiveLabel" style="display: none;" aria-hidden="true">
          <div class="modal-dialog">
            <div class="modal-content">
              <div class="modal-header">
                <h5 class="modal-title" id="exampleModalLiveLabel">Modal title</h5>
                <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
              </div>
              <div class="modal-body">
                <p>Woohoo, you're reading this text in a modal!</p>
              </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>
