Question

我有一个加载两个模块的Flex 4应用程序。第一个模块是用户登录模块，第二个模块是用户平衡。当显示用户应用程序启动登录屏幕时。当用户登录此模块时，传递给java并处理一些验证并返回到flex。在flex中，如果用户有效，则将该用户名传递给第二个模块。在该模块中，使用该名称再次将用户名传递给java并获得该用户的余额。

但我的代码无效？

正在使用此代码： -

Answer 1

因为module2在这个时候是creationComplete，所以，你可以因为module2在这个时候是creationComplete，所以，你可以在login_resultHandler加载module2时

flex4模拟从一个模块传递到另一个模块的数据
