I've been implementing the youtube API in my website, the playVideo() for example works fine, so I guess there is nothing wrong with the implementation.. but the getDuration() gets an error (not such function error)

this is how I try to do it :

function GetDuration() {
    var duration;
    if (ytplayer) {
        duration = ytplayer.getDuration();
    }
    $(".optionVideo").append("<p>" + duration + "</p>")
}

its error is that there is no such function. could anybody know what am I doing wrong ?

• 2 Example, jsFiddle? (Because according the Youtube API the function should exist.) – Styxxy Commented Jun 25, 2012 at 17:04
• Without the code as Styxxy suggests, we can't know for sure. Though looking just at this code, it could be that when this function is called, ytplayer is not fully initialized or it's the wrong object. – NateDSaint Commented Jun 25, 2012 at 17:07
• 1 @thormayer: Your jsFiddle has some errors. You forgot a ) after $(document).ready(. You forgot to include swfobject. You didn't have jQuery selected. Oh, and ytplayer is undefined. – gen_Eric Commented Jun 25, 2012 at 17:19
• @Rocket thanks, I've update it . jsfiddle/V36cL/3 – thormayer Commented Jun 25, 2012 at 17:28

You need to call GetDuration from your onYouTubePlayerReady, not from $(document).ready. The YouTube video may be ready after the DOM is.

Also, your onYouTubePlayerReady function needs to be global (jsFiddle wraps it in an anonymous function).

window.onYouTubePlayerReady = function(playerId) {
    window.ytplayer = document.getElementById("ytPlayer");
    GetDuration();
}
