我不能使用imageUrl显示模式。

我需要展示使用JavaScript的模式，但到目前为止还没有成功。在下面的代码中，我使用for循环来获取要在图片库的主页中显示的所有图像卡。但是当图像卡按钮被点击时不能显示模式。下面是包含完整代码的索引页

Bootstrap 5被设计为不使用jQuery，但是您仍然可以在页面中加载jquery，并且您的脚本将工作得很好。但是，如果您想使用bootstrap 5推荐使用的vanilla js，则只需将您的模式交互函数更改为

function showIMG(imageUrl) {
  const myModal = new bootstrap.Modal(document.querySelector('#image-modal'));
  myModal.show();
  document.querySelector('#image-show').setAttribute('src', `/media/${imageUrl}`);
}
