所以我是一名正在进行决赛的学生，我一直在从我们已经完成的其他项目中抽取例子 . 我可以得到一切工作，但结果是一个简单的纸岩剪刀蜥蜴spock游戏，但我不知道为什么结果不起作用

我想要的是结果会将函数内部的变量设置为Tie，Win，Lose然后我可以将它附加到警报但它不能正常显示为未定义 . 任何帮助将不胜感激我被卡住了 .

如果您更改此行代码：
function winResults(string)阅读：
function winResults(wcType)您还需要修复对
winResults的调用，以便在每种情况下传递的参数都是字符串文字 - 现在所有这些调用都会被写入，就像它们传递名为WIN，LOSE或TIE的变量一样 . 例如，您目前拥有的位置：winResults(TIE)你应该改为：
winResults("TIE")
