当文件可以一直播放到最后而无需在 HTML 中暂停缓冲时,使用 oncanplaythrough 属性执行脚本.
示例
您可以尝试运行以下代码来实现oncanplaythrough 属性-
<!DOCTYPE html>
<html>
<body>
<video id = "myVideo" width = "400" height = "200" controls oncanplaythrough = "display()">
<source src = "/html5/foo.ogg" type = "video/ogg" />
<source src = "/html5/foo.mp4" type = "video/mp4" />
Your browser does not support the video element.
</video>
<script>
function display() {
alert("Can be played without pausing for buffering.");
}
</script>
</body>
</html>
