几个小时以来,我一直在排除故障并寻找答案,但无济于事。正在逐字使用 API 文档中的示例代码。其他人发布并说适用于 IE9 的示例代码不适合我。我已经确认在 html 中正确设置了 doctype,我没有在 CSS 中使用 display=none 隐藏 iframe,浏览器模式是 IE9,文档模式是 IE9 标准。我的安全设置配置为中高。甚至 google 的示例页面在我的 IE9 浏览器中也不适合我。
https://developers.google.com/youtube/youtube_player_demo
当我单击“播放”尝试播放电影时(在上面的链接中),我在 IE 的脚本调试控制台中收到各种错误。第一个错误如下所示:
SCRIPT5009:“视频”未定义
请帮忙!我的示例代码如下。电影加载,我看到“API 准备就绪”警报,但在 IE9 中不会触发任何其他事件。我只是不知道我错过了什么!如果我不能很快解决这个问题,我将不得不放弃在我的项目中使用 YouTube 播放 html5 视频。
