功能性：
尝试使用5次尝试创建测验，其中每个问题页面都是从每个类别显示的随机问题。
因此，如果用户得到每个问题都是正确的，那么下一个问题就会消失，如果用户在5次尝试中的3次中得到3个问题，他们将被导航到gameWin页面。否则，如果用户已经耗尽了所有5次尝试，则会将用户导航到GameOver页面。
问题：
此时，在用户耗尽所有5次尝试后，我的console.log中显示以下错误消息：=＆gt;未捕获RangeError：超出最大调用堆栈大小。
我想请求帮助解决如何在超出调用堆栈大小时纠正以下问题。

答案 0 :(得分：3)
我基本上猜测这里的else子句＆gt; if (exist == false)导致对showQuestion的同一无限调用（由@JonasGrumann评论），而exist是除false之外的值（由@Reddy评论，调用循环导致此RangeError）。 GamePage_question_list永远不会达到@FK82评论的第六个长度，因此if的{{1}}子句永远不会执行，而是else子句，其中if (GamePage_question_list.length > 5)永远被重新调用showQuestion的else子句（我认为if (exist == false)长度应该更加程序化：5）。
基本解决方案是更新此4条件，其中大于运算符可以是GamePage_question_list.length > 5，或>=可以是5，检查长度getter是否返回值大于/等于/等于5。
