Question

enter image description here

我从事Flex应用程序。我有以下问题：事实上，在第一页中会出现一个authentification弹出窗口，只有当用户存在于数据库中时才会关闭。这部分工作正常，但我想在弹出窗口中建立一个帮助用户恢复其帐户的链接。我的问题我不知道如何导航到恢复电子邮件的页面，我使用状态，但它没有工作，请你帮我。这是authentification popup的代码

我已经更正了这段代码，但是当用户点击按钮“我忘了我的密码”时出现的面板出现在弹出窗口上，就像在屏幕截图中提到的那样

Answer 1

我没有看到您尝试更改状态的任何代码。您是否只需要在“忘记图标”图像上添加事件监听器？

<s:Image x="7" y="115" width="29" height="20" source="assets/forgot_icon.png" click="{currentstate='forgivepasswordState'}"/>
