jquery - 播放视频时保持展开框打开

标签 jquery html css iframe

我有一个图像 map ，其中包含多个点，单击这些点会放大为方框。当您在框外单击时，放大的框会关闭回到原来的位置。

查看此 fiddle

不幸的是，当我使用 IFrame 嵌入视频并单击视频播放时，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。

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

最佳答案

在尝试修复你的 JSFiddle 时，我询问了这个问题的解决方案:

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

作为引用，我将详细介绍我在您的 fiddle 上尝试过的所有内容:

  • 我尝试在您的 iframe，这样 map-point 按钮仍会保持其焦点， 因此保留其 CSS :focus 选择器。
  • 除上述内容外，我还尝试根据上面链接中投票最高的答案将 tabindex="0" 添加到您的 map-point 按钮。不幸的是，iframe 焦点覆盖了 tabindex。
  • 我尝试使用 document.getElementById('bad-map-point').scrollIntoView() 来自下一个投票最高的答案，但没有成功。
  • 我尝试在 fiddle 中使用 .manualfocus 类名和丑陋的 JS，但我弄乱了 CSS 而不是修复它，所以我恢复了它。

然后，我找到了一个很好、整洁、有效的解决方案!

  • 我在您的 map 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

  ...
}

和:

.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!

希望这对您有所帮助!
