播放视频时保持展开的框打开答案

【问题标题】：Keeping the expanded box open when a video is played播放视频时保持展开的框打开
【发布时间】：2016-07-16 17:00:40
【问题描述】：

我有一个图像地图，其中有多个点，单击时会放大到方框中。当您在框外单击时，放大的框会关闭回到原来的位置。

看到这个fiddle

不幸的是，当我使用 IFrame 嵌入视频并在视频上单击播放时，它会关闭放大的框，就像我在框外单击一样。

我相信这是因为它将焦点从 .mappoint 移开并将其带到 IFrame。

我目前的系统只使用 HTML 和 CSS，但我很乐意扩展，我只是对 jQuery 等知之甚少。

我卡住了，我希望放大的框在播放和暂停视频时保持放大。你们知道我的问题的解决方案吗？

标签： jquery html css iframe

【解决方案1】：

在尝试修复您的 JSFiddle 时，我从这个问题中询问了解决方案：

Is it possible to focus on a div using javascript focus function - Stack Overflow

作为参考，我将介绍我在你的小提琴上尝试过的所有内容：

我尝试在您的 iframe，这样map-point 按钮仍将保持其焦点，因此保留其 CSS :focus 选择器。
除上述内容外，我还尝试将tabindex="0" 添加到您的map-point 按钮，根据上面链接中投票最高的答案。不幸的是，iframe 的焦点超过了 tabindex。
我尝试使用下一个最高投票答案中的document.getElementById('bad-map-point').scrollIntoView()，但没有成功。
我尝试在小提琴中使用 .manualfocus 类名和丑陋的 JS，但我把 CSS 搞砸了，而不是修复它，所以我恢复了它。

然后，我找到了一个漂亮、整洁、有效的解决方案！

我在您的地图点上添加了hover 选择器，它适用于 iframe！

变化：

.distribution-map .map-point:active,
.distribution-map .map-point:focus,
.distribution-map .map-point:hover { //Added :hover

  ...
}

还有：

.distribution-map .map-point:active .content,
.distribution-map .map-point:focus .content,
.distribution-map .map-point:hover .content { //Added :hover

  ...
}

它很优雅，运行流畅，而且没有 JavaScript！

希望这会有所帮助！

这很有帮助！非常感谢亚伦！它现在可以与 iframe 一起使用，并且使用悬停功能看起来也更好哈哈！感谢您的辛勤工作，我永远不会想到添加悬停！干杯：D
