Youtube iFrame API 'YT is undefined'

本文关键字：is undefined YT iFrame Youtube API 更新时间：2023-09-26

我正在尝试将此代码放入模块函数中：

$(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;
  function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.PLAYING && !done) {
      // setTimeout(stopVideo, 6000);
      done = true;
    }
    if(event.data == YT.PlayerState.ENDED)
    {
      location.reload();
    }
  }
  function catchError(event)
  {
    if(event.data == 100) console.log("De video bestaat niet meer");
  }
  function stopVideo() {
    player.stopVideo();
  }
  return my;
}(VIDEO || {}, jQuery));

问题是：即使它是自执行的，也不会发生任何事情，并且不会显示iFrame。我正在尝试这样做，因为它是作业的一部分。我们必须在模块中工作。

你需要简化代码：

.HTML

<div id="player"></div>

爪哇语

$(document).ready( function() {
  console.log( "ready!" );
  loadPlayer();
});
function getArtistId() {
  return 'l-gQLqv9f4o';
}
function loadPlayer() { 
  if (typeof(YT) == 'undefined' || typeof(YT.Player) == 'undefined') {
    var tag = document.createElement('script');
    tag.src = "https://www.youtube.com/iframe_api";
    var firstScriptTag = document.getElementsByTagName('script')[0];
    firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
    window.onYouTubePlayerAPIReady = function() {
      onYouTubePlayer();
    };
  } else {
    onYouTubePlayer();
  }
}
var player;
function onYouTubePlayer() {
  player = new YT.Player('player', {
    height: '490',
    width: '880',
    videoId: getArtistId(),
    playerVars: { controls:1, showinfo: 0, rel: 0, showsearch: 0, iv_load_policy: 3 },
    events: {
      'onStateChange': onPlayerStateChange,
      'onError': catchError
    }
  });
}
  var done = false;
  function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.PLAYING && !done) {
      // setTimeout(stopVideo, 6000);
      done = true;
    } else if (event.data == YT.PlayerState.ENDED) {
      location.reload();
    }
  }
  function onPlayerReady(event) {
    //if(typeof(SONG.getArtistId()) == undefined)
    //{
    //  console.log("undefineeeed"); 
    //} 
    //event.target.playVideo();   
  }
  function catchError(event)
  {
    if(event.data == 100) console.log("De video bestaat niet meer");
  }
  function stopVideo() {
    player.stopVideo();
  }

编辑

关于您的评论q，我对代码进行了一些更改。稍后需要使用onYouTubePlayerAPIReady()调用玩家。我编辑了所有以前的代码。
