该游戏运行正常，只不过得分不会增加并且我的“裁判员”框未显示基于结果分配给我的文本。
我使用了if else语句来随机分配计算机选择并替换图像，并相应地设置computerChoice变量。我为用户输入使用了if ife语句来分配正确的图像并设置userChoice变量。然后，我使用一组单独的if else语句嵌套来比较computerCoice和userChoice变量，并在裁判框中输出文本，并将广告1指向获胜者得分框，但这部分不起作用。有任何想法吗？

您必须将用户评分右移至用户评分输入字段。其次，您的得分将在每个游戏上重置。.它不具有可交换性。.我不希望您因可交换性而错过它或它被错过。.define userScore = 0; computerScore = 0; 在函数定义之前。
试试这个
