是否可以通过轻巧的方式（如Labnol）嵌入来自YouTube频道的最新3个视频？

Question

我试图以轻量级的Labnol方式（https://www.labnol.org/internet/light-youtube-embeds/27941/）嵌入YouTube频道的最新3部视频，改编可显示最近视频的Codegena（https://codegena.com/auto-embed-latest-video-youtube-channel/）中的代码，但是没有成功。

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>


<iframe class="latestVideoEmbed" vnum='0' cid="UCBJycsmduvYEL83R_U4JriQ" width="600" height="340" frameborder="0" allowfullscreen></iframe>
<iframe class="latestVideoEmbed" vnum='1' cid="UCBJycsmduvYEL83R_U4JriQ" width="600" height="340" frameborder="0" allowfullscreen></iframe>
<iframe class="latestVideoEmbed" vnum='2' cid="UCBJycsmduvYEL83R_U4JriQ" width="600" height="340" frameborder="0" allowfullscreen></iframe>

<script>
var reqURL = "https://api.rss2json.com/v1/api.json?rss_url=" + encodeURIComponent("https://www.youtube.com/feeds/videos.xml?channel_id=");
function loadVideo(iframe){
$.getJSON( reqURL + iframe.getAttribute('cid'),
  function(data) {
     var videoNumber = (iframe.getAttribute('vnum')?Number(iframe.getAttribute('vnum')):0);
    console.log(videoNumber);
     var link = data.items[videoNumber].link;
     id = link.substr(link.indexOf("=") + 1);  
     iframe.setAttribute("src","https://youtube.com/embed/"+id + "?controls=0&autoplay=1");
  }
   );
}
var iframes = document.getElementsByClassName('latestVideoEmbed');
for (var i = 0, len = iframes.length; i < len; i++){
   loadVideo(iframes[i]);
}

</script>
