デモにはYoutubeクロームレスJavascriptプレーヤーがあります。ユーザーがプレーヤーの下のプレイリスト画像をクリックしない限り、タイトルと時間は表示されません。タイトルと時間を表示するには、ユーザーは再生リストの画像をクリックするか、次の動画に移動するのを待つ必要があります。最初のビデオの自動ロード後に何もクリックせずにタイトルと時間を書き込みたい。javascript関数の順序に問題がある可能性があります。これ以外は何も思い浮かびません。
すべてのコードは、将来の次の人々を助けるために以下にあります

// 1) Create following elements in your HTML:

//
// Variables
// -- ytplayer_playlist: an array containing YouTube Video IDs
// -- ytplayer_playitem: index of the video to be played at any given time
//
