Question

我是菜鸟，所以提前感谢你的帮助......

当我测试我的“摇滚，纸张，剪刀”javascript游戏时，“玩家与计算机”的分数似乎遍布地图。最终得分总是导致玩家或计算机获胜5，但每场比赛的日志显示得分以非常随机的增量递增和递减。

我做错了什么？

Answer 1

在getWinner（）

下需要另外一个选项

else if(playerMove == "scissors" && computerMove == "rock") { 
    winner = "computer"; 
}

Answer 2

除了剪刀（P1）与摇滚（CPU）的getWinner函数中缺少逻辑分支之外，您不会输出分数的结果。你将它作为一个字符串返回。只需将该字符串附加到当前控制台输出中，或将其全部显示在警报或其他内容中。

console.log("The final score is... " +
    "Player: " + playerWins + ", " +
    "Computer: " + computerWins);

你的getWinner函数也可以只返回一个int而不是一个字符串。 1 =玩家获胜，0 =领带，-1 = CPU获胜。
