NodeJS不更新MySQL数据库

尝试使用Javascript和NodeJS在XAMPP本地主机上更新MySQL中的数据库表，但由于某种原因，代码没有像我认为的那样处理 . 这是一个时钟程序，我所设置的只是在单击按钮时将名称插入列中的简单测试 . 基本上，当代码部分到达时没有采取任何行动（它现在只在第一个按钮上） . 我该怎么办？谢谢 .

JS

var clock = {
    bool: false,
    in: 0,
    inText: "Clock-in time: ",
    inText2: "Already clocked in: ",
    out: 0,
    outText: "Not clocked in.",
    outText2: "Clock-out time is: "
};

var rest = {
    bool: false,
    out: 0,
    outText: "Break-out time is: ",
    outText2: "Already on break: ",
    in: 0,
    inText: "Not on break.",
    inText2: "Break-in time is: "

};
