在 Javascript 中不转换为纪元的情况下增加日期对象

如何解决在 Javascript 中不转换为纪元的情况下增加日期对象

是否可以将日期对象增加一天而不将对象转换为纪元号？

例如传统方式将日期对象转换为纪元数：

var today = new Date();
var tomorrow = new Date(today.valueOf()); // copy date object without converting to epoch
tomorrow.setDate(tomorrow.getDate() + 1); // Now gets converted to epoch :'(

解决方法

set* 方法不会“转换为纪元号”，它们会修改日期的内部时间值并返回修改后的值。日期对象仍然是一个日期。

如果你想要一个添加一天并返回一个新 Date 对象的方法，编写一个函数，可能命名为 addDays，它需要一个日期和天数来添加并返回一个新的 Date 对象随着天数的增加。很多库都有这样的功能，写起来不难。

不确定是否可以在不转换的情况下做到这一点。也许之后再转换回来。

var today = new Date();
var tomorrow = new Date(today.valueOf());

const x = tomorrow.setDate(tomorrow.getDate() + 1);
console.log(x) //epoch

const z = new Date(x)
console.log(z.toString())
