Javascript 日期对象相差一个月

Question

我知道 javascript 从 0 开始计算月份。但是，我不知道在将来获取日期时如何考虑这一点。

例如，当尝试获取明天的日期时，以下代码 returns 除了月份之外的所有内容都是正确的（打印为下个月）：

const weekday = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];
const month =  ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"];

var today = new Date();
today.setUTCDate(today.getUTCDate()+1);

let newDate = weekday[today.getDay()] +' '+today.getDate()+' '+month[today.getDay()]+', '+ today.getFullYear();

console.log(newDate)

Answer 1

只需将today.getDay()替换为today.getMonth()

const weekday = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];
const month =  ["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"];

var today = new Date();
today.setUTCDate(today.getUTCDate()+1);

let newDate = weekday[today.getDay()] +' '+today.getDate()+' '+month[today.getMonth()]+', '+ today.getFullYear();

console.log(newDate)
