Question

这是我的问题的编辑。这里有相当多的代码，但问题区域低于第二组三行注释。为了防止问题出在哪里我完全错了，我把剩下的都放进去了。使用“if”语句，我可以在运行中正常显示，但不能在调试中显示。如果我摆脱条件它在调试中运行良好，但不是在常规运行。这些错误仅在测验的第一次运行时发生。在任何一种模式下运行都很好我接受第二次测验。任何帮助或建议表示赞赏。感谢...

Answer 1

状态更改后，您不应该立即运行showTheQuestion()。您所在州的组件还没有时间进行初始化。我认为你不需要那个功能，因为州是显示“显示问题”的那个。

如果你真的需要它，你应该把它添加到其中一个状态组件的创建完成事件，或者可能是状态本身的enterState事件。

不会在运行中显示数据，或者不会在调试中显示数据。
