利用SharedObjects保存信息
??????? flash没有像html的cookies，但是通过SharedObjects可以实现类似的功能。
?
??????? 创建SharedObjects并保存用户名称
???????
//create a shared object to store the user name this line actually//specifies the file name (userFile), it will have an extension of .sol ...var so:SharedObject = SharedObject.getLocal("userFile");//create and populate a userLoginName property for the shared object...so.data.userLoginName = txtUserLoginName.text;//write the file to the users disk...so.flush();?
??? 从SharedObjects中读取数据
?
??
var so:SharedObject = SharedObject.getLocal("userFile");if(so.data.userLoginName != undefined){ this.txtUserLoginName.text = so.data.userLoginName; this.txtPassword.setFocus();}?
?
? 删除SharedObjects中的信息
?
?
??
so.clear();so.flush();
