onvolumechange 属性在用户更改网页上访问的视频或音频的音量时触发。这个改变可以是音量增大、音量减小、静音等。
<!DOCTYPE html> <html> <body> <h2 id="test">Play</h2> <video id = "myid" width = "320" height = "176" controls onvolumechange = "myFunction()"> <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 myFunction() { document.getElementById("test").innerHTML = "Volume changed"; } </script> </body> </html>
