javascript - 从选定的持续时间循环播放视频

Question

我的设计中有一个视频文件，长度为 2 分钟。第一次，视频将从头开始播放，然后视频必须从 1.00 秒循环播放到 2.00 秒。使用 jquery 可以做到这一点吗？我尝试过替代方法。它有效，但视频中有跳跃。 Change video source after the first video ends 。

这是我的代码:

JQuery:

document.getElementById('bgvid').addEventListener('ended', myHandler, false);

function myHandler(e) {
   //*what to do?*//
}

HTML:

div class="anim-logo ">
    <video playsinline autoplay muted  poster="assets/img/video3.jpg" id="bgvid">
    <source src="assets/img/video3.webm" type="video/webm">
    <source src="assets/img/video3.mp4" type="video/mp4">
</video>
      </div><!--end of anim logo-->

Answer 1

你可以这样做:

var video = document.getElementById('videoElm')
video.addEventListener('ended',function(){
    // set the video's start position to the video's duration minus 10 seconds. "video.currentTime" is in milliseconds, "video.duration" is in seconds
    video.currentTime = (parseInt(video.duration) - 10) * 1000;
    video.play();
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
    <video id="videoElm" autoplay muted>
    <source src="http://clips.vorwaerts-gmbh.de/VfE_html5.mp4" type="video/webm">
</video>
</div>
