我完全不知道为什么以下代码在2019年1月3日当天执行此操作时会给我2021年...什么...我缺少什么...所以我需要一个我认为编码伙伴坐在我旁边。>。<< / p>
function daysTillChristmas()
{
var today = new Date();
var christmasDay1 = new Date(today.getFullYear() +1, 12, 25);
var test = today.getFullYear() + 1;
var christmasDay2 = new Date(2020, 12, 25);
console.log(today);
console.log("Today: " + today);
console.log("Today Full Year: " + today.getFullYear());
console.log("ChristmasDay1: " + christmasDay1);
console.log(christmasDay2);
console.log("ChristmasDay2: " + christmasDay2);
console.log("Test: " + test);
}
我的输出是...
"2019-01-03T22:54:33.294Z"
