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

var player;
function onYouTubePlayerAPIReady() {
    player = new YT.Player('player', {

      videoId: 'P2jViqMnnK4',
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange,
         'onError': onError,

      },
      playerVars: {

                'controls': 0,
                'showinfo': 0,
                'iv_load_policy': 3,
            },
    });
}

    var tag = document.createElement('script');
        tag.src = "https://www.youtube.com/player_api?enablejsapi=1&version=3";
    var firstScriptTag = document.getElementsByTagName('script')[0];
        firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
