Question

有谁知道如何根据本周日期获得下周的约会？例如，如果我有这个星期四的日期（25/6/2009），我如何使用javascript来获取下一个星期四的日期（2009年2月7日）？

Answer 1

var firstDay = new Date("2009/06/25");
var nextWeek = new Date(firstDay.getTime() + 7 * 24 * 60 * 60 * 1000);

如果您喜欢“流利的”API，也可以查看DateJS。

Answer 2

function nextweek(){
    var today = new Date();
    var nextweek = new Date(today.getFullYear(), today.getMonth(), today.getDate()+7);
    return nextweek;
}

Answer 3

function dateObject.getNextWeekDay返回对象自己的日期之后的下一个工作日。

Date.prototype.getNextWeekDay = function(d) {
  if (d) {
    var next = this;
    next.setDate(this.getDate() - this.getDay() + 7 + d);
    return next;
  }
}

var now = new Date();
var nextMonday = now.getNextWeekDay(1); // 0 = Sunday, 1 = Monday, ...
var secondNextMonday = new Date(nextMonday).getNextWeekDay(1);
console.log('Next Monday : ' + nextMonday);
console.log('Second Next Monday : ' + secondNextMonday);

Answer 4

Date.prototype.addDays = function (d) {
    if (d) {
        var t = this.getTime();
        t = t + (d * 86400000);
        this.setTime(t);
    }
};

this_week.addDays(7);

Answer 5

下周返回的函数：

function getNextWeekDay (startDate, dayOfWeek){
    var dayOffset = dayOfWeek > startDate.getDay()
        ? dayOfWeek - startDate.getDay()
        : dayOfWeek - startDate.getDay() + 7;

    startDate.setDate(startDate.getDate() + dayOffset);

    return startDate;
}

var now = new Date();

var nextMonday = getNextWeekDay(new Date(),1); // 0 = Sunday, 1 = Monday, ...
var nextSaturday = getNextWeekDay(new Date(),6);
var nextSunday = getNextWeekDay(new Date(),0);
var secondNextMonday = getNextWeekDay(new Date(now.getTime() + ( 7 *24 * 60 * 60 * 1000)),1);
alert(nextMonday+ '- '+nextSaturday+ '- '+nextSunday+ '- '+secondNextMonday);

Answer 6

const getDateAfterWeek = (week) => {
let today = new Date();
  const nextweek = new Date(
    today.getFullYear(),
    today.getMonth(),
    today.getDate() + 7 * week,
  );
  return nextweek;
}

Answer 7

一个更直接的解决方案是

let nextWeek = new Date()
nextWeek.setDate(nextWeek.getDate() + 7)

请注意，它会保留当天的当前时间。

Answer 8

这是我的解决方案。

var today = new Date; // get current date
var first = today.getDate() - today.getDay() + 1 + 7; // First day is the day of the month - the day of the week
var last = first + 6; // last day is the first day + 6

var firstday = new Date(today.setDate(first));
var lastday = new Date(today.setDate(last));

console.log(firstday, lastday);
