将嵌入式YouTube视频时间戳同步到自定义进度条
我被困在我今天一直在做的项目的一部分上。任务是同步嵌入的YouTube视频中的时间戳信息，并显示与页面底部的歌曲长度相匹配的自定义进度条。到目前为止，这是布局：
基本上，我如何提取恒定时间戳来更新进度，以及如何设置条形图的动画以完成与视频结尾的100％匹配。
我已经禁用了用户对嵌入式YouTube视频进行scrobble的功能。注意：用户不应该使用自定义进度条更改youtube视频的时间（它只是用于可视队列）！
如果您需要更多说明，请与我们联系。 HTML和CSS如下。谢谢！！ ：）

热爱你的问题！
-
使用
id="player"的div切换iframe（您想要的任何名称，可以是“my_own_player”或“XYZ_player”......） 然后现在你已经准备好将你的iframe播放器转换为Youtube播放器对象，这样你就可以使用“IFrame播放器API”来实现你想要的效果。 -
确保按照您想要的iframe方式设置div的样式。
-
只需添加以下脚本：
//This function creates an <iframe> (and YouTube player) function onYouTubeIframeAPIReady() { player = new YT.Player("player", { height: "850", width: "477", videoId: "2GvIq2SpVFM", events: { "onReady": onPlayerReady, "onStateChange": onPlayerStateChange } }); } -
将
videoId替换为您的视频ID。 -
将
height替换为您视频的高度。 -
将
width替换为您视频的宽度。 -
getCurrentTime（）
-
getDuration（）
现在，要像你说的那样获得“视频时间戳”，以便轻松获得进度条。玩家对象有两种方法可以做到这一点：
getDuration是视频的总时间（以秒为单位）。虽然getCurrentTime是视频播放的时间。划分
getCurrentTime getDuration，您将获得进度条的比率。将它乘以100，即可获得所需的百分比：
(player.getCurrentTime()/player.getDuration())*100;
就是这样！获得代表 getCurrentTime / getDuration 的百分比后，html进度条就不需要任何其他内容。只需将html bar元素的宽度设置为该百分比。只需确保红色“条形”具有背景（另一个div），它很容易被识别为进度条的向外限制。或者只是将它放在页面上可见的另一个div中，如下所示：
<div id="progress" style="width: 800px; height: 10px; border: 1px solid #fff;">
<div id="bar" style="width: 1px; height: 10px; background: #f00;"></div>
</div>
