当中的提示改变时执行脚本HTML 元素?
当提示改变时,oncuechange 属性在 HTML 中触发。它与 <track> 元素配合使用。
<video> <track oncuechange = "alert(‘Changed!’)”> </video>
示例
你可以尝试运行以下代码来实施oncuchange 属性 −
<!DOCTYPE HTML> <html> <body> <video width = "300" height = "200" controls autoplay> <source src = "/html5/foo.ogg" type = "video/ogg" /> <source src = "/html5/foo.mp4" type = "video/mp4" /> <track src = "subtitles_en.vtt" kind = "subtitles" srclang = "en" label="English" oncuechange = "alert(‘Changed!’)”> Your browser does not support the video element. </video> </body> </html>
