我是 Javascript 新手，遇到了问题。我有一个 Javascript 文件，我已链接到一个 HTML 文件，当我仅将它用于一个功能时，它工作正常，但现在我添加了第二个极其相似的功能，它已停止工作，我已经对其进行了多次搜索，但无法确定它为什么会停止工作。我的 HTML 文件如下。
<head>

很抱歉这可能是一个明显的错误，感谢你们花时间查看此问题。
最佳答案
我认为 } 丢失了
if (theSecondAnswer == "a=7, b=9, c=17") {
answers.push("m5");
answers.push("s2");
} // <==== This is missing
