当HTML中的<cue>元素发生变化时执行脚本?
当提示改变时,oncuechange 属性在HTML中触发。它与元素一起使用。
<video> <track oncuechange = "alert(‘Changed!’)”></video>
Example
您可以尝试运行以下代码来实现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>
