尝试创建具有多个起点的 HTML5 视频序列

如何解决尝试创建具有多个起点的 HTML5 视频序列

我对 JavaScript 还很陌生。

我正在创建一个视频网站，最终用户可以在其中点击他们喜欢的任何视频并开始观看。我希望在第一个选定的视频结束后自动播放一系列视频。因此，假设最终用户选择 videoSource[2]，数组从那里开始并在 videoSource[2] 结束时播放 videoSource[3]。

I have managed to create an array that triggers the sequence to play,when the first video - videoSource[0] - has ended,however,when another video is selected,the sequence does not play.

我已阅读有关该主题的所有帖子，但似乎没有一个能解决我的问题。

这是我的 javascript 代码：

<script type='text/javascript'>

let videoSource = new Array();
videoSource[0] = 'VID/Home.mp4';
videoSource[1] = 'VID/MLSS.mp4';
videoSource[2] = 'VID/Ana.mp4';
videoSource[3] = 'VID/FRIEND.mp4';
videoSource[4] = 'VID/LVAletterBox.mp4';

let i = 0; 
const videoCount = videoSource.length;
const element = document.getElementById("videoPlayer");
 
function videoPlay(videoNum) {
    element.setAttribute("src",videoSource[videoNum]);
    element.autoplay = true;
    element.load();
    element.play();
}
document.getElementById('videoPlayer').addEventListener('ended',myHandler,false);
 
videoPlay(0); 
 
function myHandler() {
    i++;
    if (i == videoCount) {
        i = 0;
        videoPlay(i);
    } else {
        videoPlay(i);
    }
}


</script>

这是我的 HTML 代码：
