I'm trying the new iFrame Api examlpe @ http://code.google.com/apis/youtube/iframe_api_reference.html (Code Below here..)
Everythings work prerfect on Chrome, safari but there is an Error reporting on firefox 3.0 and IE6 -> JSON is undefined on line:13 The player is still working but javascript crash completely.
I tried to get json2.js library (http://www.json.org/) script on top of page but nothing works better. How can I arrange this JSON Error on these old browsers ?
<html>
<body>
<!-- 1. The <div> tag will contain the <iframe> (and video player) -->
<div id="player"></div>
<script src="js/json2.js"></script>
<script language="javascript">
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "http://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'u1zgFlCw8Aw',
playerVars: { 'autoplay': 1, 'controls': 0, 'showinfo': 0, 'loop': 1, 'rel' : 0, 'showsearch' : 0, 'enablejsapi' : 1},
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.playVideo();
}
function onPlayerStateChange(event) {
//
}
</script>
</body>
</html>

I got bitten by this too. The Youtube iframe API needs the HTML5 postMessage feature, which IE7 and other old browsers do not have.
