bytetotal = _root.getBytesTotal();
loaded = int(byteloaded /bytetotal * 100);

percent = loaded + "% ( " + int(byteloaded/1000) + " K / " + int(bytetotal/1000) + " K )";
percent = percent + "下载速度：" + int(byteloaded/t) + " K/s";
load_bar.gotoAndStop( loaded );
timeloaded = int(t/1000);
timeremain = int(timeloaded * (bytetotal- byteloaded) / byteloaded);
timeremain = int(timeremain / 60) + "分''''" + int(timeremain % 60) + "秒"";
timeloaded = int(timeloaded / 60) + "\''''" + int(timeloaded % 60) + "\"";
downloadtime = "已用时间：" + timeloaded + "剩余时间：" + timeremain;

AS3只需要加一小段就可以了
var request: URLRequest = new URLRequest( "f
