我正在创建一个通过YT api嵌入的youtube播放器,但我一直收到一个警告,即变量YT未定义.我可以看到youtube API的脚本被包含在内,它应该创建变量YT - 所以为什么这不起作用？它适用于我网站上的其他地方.

这是链接:

和我的代码:

<script>

 $(document).ready(function() {

    var tag = document.createElement('script');
    tag.src = "http://www.youtube.com/player_api";
    var firstScriptTag = document.getElementsByTagName('script')[0];
    firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
    var player;

    var videoSupport = Modernizr.video;
    var ua = navigator.userAgent.toLowerCase();
    var vid = {};

    var params = { allowScriptAccess: "always" };
    var atts = { id: "video_player_flash" };

    {exp:channel:entries channel="creators" dynamic="off" entry_id="{segment_3}" sort="asc" limit="1"}  
    vid.description = "{creator_description}";
    vid.videoID = '{segment_4}';
    vid.link = encodeURI("{creator_link}");
    vid.title = "{title}";
    vid.photos = [];
    {creator_work}  
        vid.photos[{row_index}] = {};
        vid.photos[{row_index}].url = "{work_img}"; …

我正在尝试将此代码放在模块函数中:

$(document).ready(function()
    {
        VIDEO.onYouTubeIframeAPIReady();
}


        var VIDEO = (function (my, $){
var tag = document.createElement('script');
var onPlayerStateChange;
  tag.src = "https://www.youtube.com/iframe_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  var player;


   my.onYouTubeIframeAPIReady =function() {
    player = new YT.Player('player', {
      height: '490',
      width: '880',
      videoId: SONG.getArtistId(),
      playerVars: { controls:1, showinfo: 0, rel: 0, showsearch: 0, iv_load_policy: 3 },
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange,
        'onError': catchError
      }
    });
  }

  function onPlayerReady(event) {


  if(typeof(SONG.getArtistId()) == undefined)
  {
    console.log("undefineeeed"); 
  } 


    event.target.playVideo();   
  }

  var done = false; …

我在我的 React 网站上使用Youtube Player API 。当我在网站上尝试时，出现以下错误：TypeError: Cannot read property 'ready' of undefined。这是我正在使用的代码：

var player;
function loadVideo() {
    window.YT.ready(function () {
      new window.YT.Player("player", {
        height: "390",
        width: "640",
        videoId: "M7lc1UVf-VE",
        events: {
          onReady: onPlayerReady,
          onStateChange: onPlayerStateChange,
        },
      });
    });

    function onPlayerReady(event) {
      event.target.playVideo();
      player = event.target;
    }

    function onPlayerStateChange(event) {
      var videoStatuses = Object.entries(window.YT.PlayerState);
      console.log(videoStatuses.find((status) => status[1] === event.data)[0]);
    }
  }

  useEffect(() => {
    setMaxDuration("06:00");
    var tag = document.createElement("script");
    tag.src = "https://www.youtube.com/iframe_api";
    var firstScriptTag = document.getElementsByTagName("script")[0];
    firstScriptTag.parentNode.insertBefore(tag, …
