HTML5 video loop src change on end play function not working
提问by Dhamu
I have a number of videos playing one by one in the same HTML5 video player
我有许多视频在同一个 HTML5 视频播放器中一一播放
HTML
HTML
<video id="homevideo" width="100%" autoplay autobuffer>
<source src="app/video1.mp4" type='video/mp4' />
</video>
JS
JS
video_count = 1;
videoPlayer = document.getElementById("homevideo");
videoPlayer.addEventListener("ended", function (){
video_count++;
if (video_count == 4) video_count = 1;
var nextVideo = "app/video" + video_count + ".mp4";
videoPlayer.src = nextVideo;
videoPlayer.play();
}, false);
If I put an alert before playing, it's working. But without the alert it's not. Initialize the second video play:
如果我在播放前发出警报,它就会起作用。但没有警报就不行了。初始化第二个视频播放:
videoPlayer.src = nextVideo;
alert("a");
videoPlayer.play();

The html5 video element has an own eventtype onended, you dont need your own eventlistener.
html5 视频元素有自己的事件类型,您不需要自己的事件侦听器。
Html:
网址:
<video id="homevideo" width="100%" autoplay onended="run()">
<source src="app/video1.mp4" type='video/mp4'/>
</video>
and
和
Script:
脚本:
video_count =1;
videoPlayer = document.getElementById("homevideo");
function run(){
video_count++;
if (video_count == 4) video_count = 1;
var nextVideo = "app/video"+video_count+".mp4";
videoPlayer.src = nextVideo;
videoPlayer.play();
};
PS: Keep in mind that providing only one format for your video is not enough since no single format is supported by all major browsers yet.
PS:请记住,仅为您的视频提供一种格式是不够的,因为所有主要浏览器尚不支持单一格式。
