SharedObject功能强大，可以保存本地永久数据，存储和共享数据，实时共享数据，下面是一个保存本地数据的例子：
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
import mx.controls.Alert;
    private function save():void {
            // 创建一个本地保存数据的对象s  
            var test:SharedObject = SharedObject.getLocal("testcookie");
            test.data.user = user.text;
            test.data.psw = age.text;
            test.flush(); //提交保存
        }
        private function show():void{
            var test2: SharedObject = SharedObject.getLocal("testcookie");
            Alert.show(test2.data.user);
            Alert.show(test2.data.psw);
        }
