執行一個腳本當提示更改在HTML中的元素?
當提示更改時,HTML中的oncuechange 屬性被觸發。它與<track>元素一起使用。
<video> <track oncuechange = "alert(‘Changed!’)”> </video>
示例
你可以嘗試執行以下程式碼實現oncuchange 屬性 -
<!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>
