文件加载类的一个BUG

import flash.net.FileReference;
import flash.events.Event;
load();
function load():void
{
	var file:FileReference = new FileReference();
	file.browse();
	file.addEventListener(Event.SELECT,onSelect);
	file.addEventListener(Event.COMPLETE,onComplete);
}

function onSelect(e:Event):void
{
	var target:FileReference = e.currentTarget as FileReference;
	target.load();
}

function onComplete(e:Event):void
{
	trace("load complete");
}

这样加载是没法载入文件的。把file抽成全局变量试试。yeath,成功了;
