当文件准备开始以HTML播放时执行脚本?
您可以将oncanplay 属性用于以下属性-<audio>,<embed>,<object>和<video>。
示例
<!DOCTYPE HTML> <html> <body> <video width = "300" height = "200" 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> alert("我准备开始。"); </script> </body> </html>
