I have an iframe with a video, for example:
</script>
<ins class="adsbygoogle"
     style="display:block"
     data-ad-client="ca-pub-5408099190056760"
     data-ad-slot="7305827575"
     data-ad-format="auto"
     data-full-width-responsive="true"></ins>
<script>
     (adsbygoogle = window.adsbygoogle || []).push({});
</script>        </div>
                      <div class="relativetags">
              相关标签:

      <div class="fly-panel detail-box" id="flyReply">
        <fieldset class="layui-elem-field layui-field-title" style="text-align: center;">

<p>Sure. You can use VideoJS. You may have a hard time getting control of the iFrame as you put it. You can embed various video hosting sites' video with VideoJS, supposedly. </p>

<pre><code>&lt;script&gt;
VideoJS.DOMReady(function() {
var player = VideoJS.setup("current_video");
player.play();
player.currentTime(666);
});
&lt;/script&gt;
</code></pre>

<p>That iframe will give you trouble, however in general you can do this without a library.</p>

<pre><code>// get the video element
let video = document.getElementsByTagName('video')[0]
// jump it to a specific time
video.currentTime = 10 // the number of seconds you want it to be at
</code></pre>
                                                                        <div class="appendcontent">

<p>Unfortunately, not always. There is no single solution to seek a time in a <strong>Flash</strong> video if you don't know what the source of the video is.</p>

<p>If you ever encounter HTML5 video, you can try this: Start HTML5 video at a particular position when loading?</p>
