import flash.display.Loader;import flash.net.URLRequest;loader对象的方法以：load（）方法，使用如下：var loader:Loader = new Loader();//注册加载器var url:URLRequest=new URLRequest("1.png");//注册加载地址loader.load(url);addChild(loader);loader.contentLoaderInfo.addEventListener(Event.COMPLETE,LoadComplete);//Event.COMPLETE事件是一个异步的事件
