loading multiple video players with youtube api

Question

I need to load more than one video with youtube's API. This is my first time using it so I'm not sure what I'm doing wrong, but this is what I'm trying:

  var player;
  var player2;
  function onYouTubePlayerAPIReady() {
    player = new YT.Player('player', {
      videoId: 'hdy78ehsjdi'
    });
    player2 = new YT.Player('player', {
      videoId: '81hdjskilct'
    });
  }

Answer 1

The first parameter of new YT.Player needs to be the id of the HTML element (f.e. a DIV) to be replaced with an iframe to the video. As you use 'player' for both of these objects, you will load both into the same element.

<div id="ytplayer1"></div>
<div id="ytplayer2"></div>

<script>
  var player;
  var player2;
  function onYouTubePlayerAPIReady() {
    player = new YT.Player('ytplayer1', {
      height: '390',
      width: '640',
      videoId: 'hdy78ehsjdi'
    });
    player2 = new YT.Player('ytplayer2', {
      height: '390',
      width: '640',
      videoId: '81hdjskilct'
    });
  }
</script>

Parameters of the functions are described in the Youtube API documentation:
https://developers.google.com/youtube/iframe_api_reference#Loading_a_Video_Player (EDIT: changed to the right link)

Answer 2

Since onYouTubeIframeAPIReady function is supposed to called only once the following approach could be used:

• initialize and save video player information (ControlId,width,height,VideoId) in array

• call onYouTubeIframeAPIReady function to create all the video players

Example

var playerInfoList = [{id:'player',height:'390',width:'640',videoId:'M7lc1UVf-VE'},{id:'player1',height:'390',width:'640',videoId:'M7lc1UVf-VE'}];

      function onYouTubeIframeAPIReady() {
        if(typeof playerInfoList === 'undefined')
           return; 

        for(var i = 0; i < playerInfoList.length;i++) {
          var curplayer = createPlayer(playerInfoList[i]);
        }   
      }
      function createPlayer(playerInfo) {
          return new YT.Player(playerInfo.id, {
             height: playerInfo.height,
             width: playerInfo.width,
             videoId: playerInfo.videoId
          });
      }
