没有实用程序的一行程序:

new Date(+new Date() + 60000*15) // +15 minutes

let d = new Date();
d.setMinutes(d.getMinutes() + 30);

// console.log(d)

新日期() var newDateObj =新日期(); (+ 30 * 60 * 1000); 游戏机。log (newDateObj);

事情就是这么简单;

let initial_date = new Date;
let added30Min = new Date(initial_date.getTime() + (30*60*1000));

简单地，你可以在momnet库中使用这段代码:

console.log(moment(moment()).add(30,"minutes").format('MM/DD/YYYY hh:mm:ss'));

我总是创建7个函数，在JS中使用date: addSeconds, addMinutes, addHours, addDays, addWeeks, addMonths, addYears。

你可以在这里看到一个例子:http://jsfiddle.net/tiagoajacobi/YHA8x/

使用方法:

var now = new Date();
console.log(now.addMinutes(30));
console.log(now.addWeeks(3));

这些是函数:

Date.prototype.addSeconds = function(seconds) {
  this.setSeconds(this.getSeconds() + seconds);
  return this;
};

Date.prototype.addMinutes = function(minutes) {
  this.setMinutes(this.getMinutes() + minutes);
  return this;
};

Date.prototype.addHours = function(hours) {
  this.setHours(this.getHours() + hours);
  return this;
};

Date.prototype.addDays = function(days) {
  this.setDate(this.getDate() + days);
  return this;
};

Date.prototype.addWeeks = function(weeks) {
  this.addDays(weeks*7);
  return this;
};

Date.prototype.addMonths = function (months) {
  var dt = this.getDate();
  this.setMonth(this.getMonth() + months);
  var currDt = this.getDate();
  if (dt !== currDt) {  
    this.addDays(-currDt);
  }
  return this;
};

Date.prototype.addYears = function(years) {
  var dt = this.getDate();
  this.setFullYear(this.getFullYear() + years);
  var currDt = this.getDate();
  if (dt !== currDt) {  
    this.addDays(-currDt);
  }
  return this;
};
