我正在尝试使用 JQuery UI 使内联 SVG 元素可拖动,以便我可以制作自定义视频控件。
不幸的是我运气不佳。我试过这个SO answer在我的代码中,但没有到达任何地方。我还成功地拖动了 SVG 图像,但不是内联的。难道只是 JQuery UI 不能很好地与内联 SVG 配合使用吗?
有什么建议的替代方案吗?

最佳答案
我会调试一下,看看能否解决问题。 我注意到的第一件事是你没有关闭你的 html 标签;)
还有为什么当你使用 jquery 时“document.querySelector”...
编辑:
您似乎使用了很多非 jquery 代码,目前正在清理您的代码,我将修复 slider 。
编辑2:
您忘记了在使用 slider 滑动后还需要更新视频进度,我也为此添加了代码。
编辑3:
这是一些工作代码:https://jsfiddle.net/seahorsepip/gLudkdd9/5/
它仍然很困惑并且工作有问题,你用 4% 和 94% 所做的事情也没有任何意义。
实际上,您甚至不需要 jquery ui 只是为了使其可拖动,使用 mousedown mousemove 和 mouseup 来编写它非常容易。
