AS3语言注意事项汇总

1. 在IE中，主DisplayObject加入stage后，可能其大小还是0，这时可以通过监听resize信息，在主DisplayObject获得正确的大小后，运行主要程序。需要注意的是在这个过程中，可能会触发多次resize事件。

package
{
    import flash.events.Event;
    import flash.display.Sprite;
    import flash.display.StageAlign;
    import flash.display.StageScaleMode;

    [SWF(width="400", height="300", frameRate="60", backgroundColor="#000000")]
    public class Startup extends Sprite
    {
        public function Startup()
        {
            // These settings are recommended to avoid problems with touch handling
            stage.scaleMode = StageScaleMode.NO_SCALE;
            stage.align = StageAlign.TOP_LEFT;

            if((stage.stageWidth != 0)&&(stage.stageHeight != 0)){
                init();
            } else {
                //work around IE flash embedding issues
                trace('stage is 0x0; listening for resize event');
                stage.addEventListener(Event.RESIZE, onResize);
            }
        }

        private function onResize(e:Event):void
        {
            if((stage.stageWidth != 0)&&(stage.stageHeight != 0)){
                stage.removeEventListener(Event.RESIZE, onResize);
                MainProcess();
            }
        }

        private function MainProcess():void
        {

        }
    }
}
