对于初学者来说，您的代码确实效率低下且混乱，我绝对不建议重新启动。但是，如果您想保留已有的代码，为了制作分数计数器，您不需要函数，只需根据结果函数中的结果添加到分数即可。
这是更新后的 HTML 代码
和您的 javascript 代码，
您也不需要在所有内容中放置 span 标记，这是一种非常糟糕的方法。
Well for starters your code is really inefficient and messy, and I wouldn't definitely recommend re-starting. But if you want to keep the code you already have, to make the score counter you don't need a function, just add to the score based of the result in the result function.
Here's the updated HTML code
and your javascript code
also you do not need to put span tags in everything, it's a really bad way of doing it.
据我了解，您想将游戏的获胜者保存在某个地方，以便稍后查看，对吧？
好吧，也许你可以使用 localStorage；
这样，您所要做的就是获取结果并将它们存储在 localStorage 中，如下所示：
要从 localStorage 获取结果，您可以将其保存在变量中：
这样，如果 localStorage 上没有任何结果， checkResult 将返回空值；
from what I understand you want to save the winner of the game somewhere so you can check it later right?
Well, maybe you can use localStorage;
With that, all you gotta do is take the result and store them on localStorage, like this:
and for get the result from localStorage, you can save it on a variable:
in that way if do not have any results on localStorage, checkResult will return null;
