Video controls in JS

hey guys,

i wanted to add a button to enlarge the video to full screen, is there anyway to do it in JS?
for my buttons i use it like that:

<script type="text/javascript">
    function play() {
        if (ytplayer) {
            ytplayer.playVideo();
        }
    }
    function pause() {
        if (ytplayer) {
            ytplayer.pauseVideo();
        }
    }
    function stop() {
        if (ytplayer) {
            ytplayer.stopVideo();
        }
    }
</script>

Hi,

the only thing can be useful is


player.setSize(width:Number, height:Number):Void

but I don’t know if it works the way you want (never used)

Bye.
