当媒体到达HTML末尾时，使用HTML中的onended 属性执行脚本。您可以添加“感谢您收看”，“敬请期待！”等消息。
您可以尝试运行以下代码以实现onended 属性-
<!DOCTYPE HTML>
<html>
<body>
<video width = "300" height = "200" controls onended = "display()">
<source src = "/html5/foo.ogg" type = "video/ogg" />
Your browser does not support the video element.
</video>
<script>
function display() {
alert ("Thank you for watching! Stay tuned!");
}
</script>
</body>
</html>
