flex记住密码等操作

1 在密码正确的情况下，如果“记住密码”是选中的，那么将用户名，密码和记住密码的状态保存
var userInfoCookie:SharedObject = SharedObject.getLocal("userInfoCookie");
                        if(rememberPsw.selected)
                        {
                        userInfoCookie.data.userName = nameid.text;
                        userInfoCookie.data.userPsw = passwordid.text;
                        userInfoCookie.data.isRememberPsw = true;
                        }
                        else
                        {
                            userInfoCookie.data.userName = "";
                            userInfoCookie.data.userPsw = "";
                            userInfoCookie.data.isRememberPsw = false;
                        }
                        userInfoCookie.flush();
2 在加载登录界面时调用initialize="preInit()"方法：
var userInfoCookie:SharedObject = SharedObject.getLocal("userInfoCookie");
                if(userInfoCookie.data.hasOwnProperty("userName") && userInfoCookie.data.isRememberPsw && userInfoCookie.data.userName != "")
                {
                    this.nameid.text = userInfoCookie.data.userName;
                    this.passwordid.text = userInfoCookie.data.userPsw;
                    this.rememberPsw.selected =  true;
                }
