检测客户端是否使用 HTML5 Youtube 播放器 [英] Detect if client using HTML5 Youtube player

问题描述

在带有嵌入式 YouTube 播放器的页面上，是否可以判断正在使用哪个版本的播放器(HTML5 或 Flash)?

On a page with an embedded YouTube player, is it possible to tell which version of the player is being used (HTML5 or Flash)?

推荐答案

事实证明，您可以检查播放器上某些属性是否存在.最明显的可能是 cueVideoByFlashvars，所以你可以这样做:

It turns out you can check for the existence/absence of certain properties on the player. The most obvious one is perhaps cueVideoByFlashvars, so you can do:

<代码>var isHtml5Player = !player.cueVideoByFlashvars;

正如 Jeff 提到的那样，不得不依赖它并不好，因为它随时可能发生变化.

As Jeff mentions it's not great to have to rely on this as it could change at any time.
