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(&lsquo;Changed!&rsquo;)&rdquo;></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(&lsquo;Changed!&rsquo;)&rdquo;>         Your browser does not support the video element.      </video>   </body></html>
