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)
}

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);
}

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)
}

在遵循其他人的建议之前，你首先需要解析你的字符串:

var dateString = "2010-09-11";
var myDate = new Date(dateString);

//add a day to the date
myDate.setDate(myDate.getDate() + 1);

如果你想让它恢复到相同的格式，你必须“手动”完成:

var y = myDate.getFullYear(),
    m = myDate.getMonth() + 1, // january is month 0 in javascript
    d = myDate.getDate();
var pad = function(val) { var str = val.toString(); return (str.length < 2) ? "0" + str : str};
dateString = [y, pad(m), pad(d)].join("-");

但我建议像其他回复中提到的那样获得Date.js，这将对你有很大帮助。

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:

使用这个函数，它解决了我的问题:

    let nextDate = (daysAhead:number) => {
      const today = new Date().toLocaleDateString().split('/')
      const invalidDate = new Date(`${today[2]}/${today[1]}/${Number(today[0])+daysAhead}`)
      if(Number(today[1]) === Number(12)){
        return new Date(`${Number(today[2])+1}/${1}/${1}`)
      }
      if(String(invalidDate) === 'Invalid Date'){
        return new Date(`${today[2]}/${Number(today[1])+1}/${1}`)
      }
        return new Date(`${today[2]}/${Number(today[1])}/${Number(today[0])+daysAhead}`)
    }
