javascript - 在 JavaScript 中创建复制警报？
问题描述
嘿，我是新的 Web 开发人员，正在做一个报价网站项目。
我创建了一个 Html 页面，其中有一些引号，所有引号下方都有一个复制按钮。
您可以访问我的 CodePen 以清楚地理解问题 https://codepen.io/Akash11166666/pen/JjRzqzp
（我已经显示了来自 Javascript 的复制按钮和引号，因此您无法在 HTML 中找到这些元素。）
如您所见，我的 CodePen 它们工作得很好，但我们不知道文本是否被复制。（在我的 CodePen 中，我已经使跨度可见）所以我需要在<span>Copied</span>单击每个复制按钮时可见。您无法在 HTML 中找到，因为它来自 javascript，与创建复制按钮相同。它们应该是动态的，当单击相应的复制按钮时，span元素应该在几秒钟后可见和不可见。
我已经尝试了很多方法来解决这个问题，但它们都不起作用，尽管我是 javascript 新手，而且我对此不太了解。
我的 CodePen 项目供参考

我会再次告诉我的问题，<span>Copied</span>当单击每个复制按钮时，我需要一个可见的。
