我创建了这个，有两个视频链接会弹出相同的视频。如何添加第二个视频，以便当我单击底部链接时会弹出第二个视频？我认为我需要向函数show()添加一个参数。也许为“video”元素的每个视频创建一个单独的类。我非常感谢对这项任务的任何帮助。另外，如果您知道有关编辑 DOM 元素以及用于 CSS 网页的常见 Javascript 函数的在线资源，请告诉我。 Javascript，例如 classlist.toggle、onclick="show();"我确实计划制作一个涵盖 Javascript 的课程视频，也许是“2023 年完整的 Javascript 课程：从零到专家！”作者：乔纳斯·施梅特曼。

刚刚向每个视频弹出 div 添加了唯一 ID（例如“popup1”和“popup2”）。
