示例您可以尝试运行以下代码来了解如何在媒体准备开始播放时执行脚本 -
<!doctype html><html> <body> <video id = "myid" width = "320" height = "176" controls oncanplay="display()"> <source src = "/html5/foo.ogg" type = "video/ogg" /> <source src ="/html5/foo.mp4" type = "video/mp4" /> your browser does not support the video element. </video> <script> function display() { alert("video loaded!"); } </script> </body></html>
以上就是当媒体准备好开始播放时，在html中执行脚本的详细内容。
