Question

On demo I am trying to develop a chromeless Youtube player. Control links on that link works fine on Firefox and Chrome but doesn’t work on Internet Explorer. How can i fix this problem? I think problem is related with id’s but maybe i am confused because nothing that i have tried is not solve my problem.

  var ytplayer_playlist = [ ];
  var ytplayer_playitem = 0;
  swfobject.addLoadEvent( ytplayer_render_player );
  swfobject.addLoadEvent( ytplayer_render_playlist );
  function ytplayer_render_player( )
  {
     swfobject.embedSWF
    (
      'http://www.youtube.com/apiplayer?video_id='+ ytplayer_playlist[ ytplayer_playitem ] + '&enablejsapi=1&autoplay=1&loop=1&version=3&rel=0&fs=1&playerapiid=ytplayer',
      'ytplayer',
      '400',
      '225',
      '10',
      null,
      null,
      {
        allowScriptAccess: 'always',
        allowFullScreen: 'true'
      },
      {
        id: 'ytplayer'
      }
    );

  }
  function ytplayer_render_playlist( )
  {
    for ( var i = 0; i < ytplayer_playlist.length; i++ )
    {
      var img = document.createElement( "img" );
      img.src = "http://img.youtube.com/vi/" + ytplayer_playlist[ i ] + "/default.jpg";
      var a = document.createElement( "a" );
      a.href = "#ytplayer";

function stop() {

Answer 1

Replace these calls (calling on the object ytplayer):

ytplayer.pauseVideo();
ytplayer.playVideo();
// ...

With the following:

document.getElementById('ytplayer').pauseVideo();
// ...

Internet Explorer treats ytplayer object as HTMLCollection:

With selecting the element explicitely you can call the function.
