明天在纯JS的一行，但它是丑陋的!

new Date(new Date().setDate(new Date().getDate() + 1))

结果如下:

Thu Oct 12 2017 08:53:30 GMT+0200 (Romance Summer Time)

未来5天:

var date = new Date(),
d = date.getDate(),
m = date.getMonth(),
y = date.getFullYear();


for(i=0; i < 5; i++){
var curdate = new Date(y, m, d+i)
console.log(curdate)
}

两种方法:

1:

var a = new Date()
// no_of_days is an integer value
var b = new Date(a.setTime(a.getTime() + no_of_days * 86400000)

2:类似上述方法

var a = new Date()
// no_of_days is an integer value
var b = new Date(a.setDate(a.getDate() + no_of_days)

使用vanilla js递增日期年份:

start_date_value = "01/01/2019"
var next_year = new Date(start_date_value);
next_year.setYear(next_year.getYear() + 1);
console.log(next_year.getYear()); //=> 2020

以防有人想增加date (day)以外的值

JavaScript日期的时区/夏令时感知日期增量:

function nextDay(date) {
    const sign = v => (v < 0 ? -1 : +1);
    const result = new Date(date.getTime());
    result.setDate(result.getDate() + 1);
    const offset = result.getTimezoneOffset();
    return new Date(result.getTime() + sign(offset) * offset * 60 * 1000);
}

使用dateObj.toJSON()方法获取日期的字符串值参考:https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toJSON 从返回值中切片日期，然后增加所需的天数。

var currentdate = new Date();
currentdate.setDate(currentdate.getDate() + 1);
var tomorrow = currentdate.toJSON().slice(0,10);
