Question

（我正在使用jQuery，bootstrap和bootbox，因为JSFiddle没有显示console.log）

所以我正在尝试console.log当前的第二个，但它只是记录页面加载的第二个。我将它从一个变量更改为一个函数，看看它是否会有所帮助，但它仍然会做同样的事情。

$(document).ready(function () {
    var d = new Date();
    // I changed this from a variable that was just
    // var secs = d.getSeconds();
    // Thinking that it was saving the second in which it loaded
    // As the second, but that still didn't help.
    var secs = function () {
        return d.getSeconds();
    };
    setInterval(function(){
        // This bootbox.alert is like a fancy console.log
        bootbox.alert(secs().toString());
        // Change the 100000 to 1000 when you want to run the code, and change it again when you want to edit it as It'll keep spamming you.
    }, 100000);
});

每次要更新秒数时，都需要调用new Date()。

将您的secs功能更改为以下内容并删除d变量。

var secs = function () {
    return new Date().getSeconds();
};

每次拨打secs();

时，此更改都会查找当前时间

您的实施引用了相同的时间点variable d，这就是秒数似乎没有变化的原因。
