                        fileStream.open(file,FileMode.READ);

    //算高度仅供参考

introTxt.height=(Math.floor(Number(fileStream.bytesAvailable/))+)*;

                        introTxt.text=fileStream.readMultiByte(fileStream.bytesAvailable,"gbk");

                        trace(introTxt.height);

                        scrollerId.verticalScrollBar.value=;
