Question

I’m building a very simple mp3 player. What I need is to make it start playing the music on load, as soon as the page has loaded. Any ideas how should I do that?

This is my code so far. I have this function called musicPlay, I wish to let that function execute on page load.

package {
    import flash.display.MovieClip;
    import flash.events.MouseEvent;
    import flash.media.Sound;
    import flash.net.URLRequest;

    public class mp3Player extends MovieClip {

        public function mp3Player(){

            btnPlay.addEventListener(MouseEvent.CLICK, musicPlay);

            function musicPlay (evt:MouseEvent):void {
                var myMusic:Sound = new Sound();
                var soundFile:URLRequest = new URLRequest('background.mp3');
                myMusic.load(soundFile);
                myMusic.play();
            }

        }
    }
}

The concept of pages doesn’t really work well in an application, and Flex is primarily used for applications. However, in this case, I suspect you can achieve the desired functionality using the applicationComplete method of Flex’s Application tag.

If you use a generic event as the argument to your musicPlay function, it can respond to both the click and the applicationComplete events.

        public function musicPlay (evt:Event):void {
            var myMusic:Sound = new Sound();
            var soundFile:URLRequest = new URLRequest('background.mp3');
            myMusic.load(soundFile);
            myMusic.play();
        }

The syntax you provided us weird, because you normally wouldn’t define a function inside another function. ( Will that even compile? )

Update, since the poster is not using the Flex Framework, the applicationComplete event won’t exist. As such, I’d probably look into putting the mp3 player functionality on a single frame, and doing something on an enterFrame event.
