我想获得一个日期对象，它比另一个日期对象晚30分钟。我如何用JavaScript做到这一点?
当前回答
var myDate= new Date();
var MyNewDate = new Date
(myDate.getFullYear(),myDate.getMonth(),myDate.getDate(),myDate.getMinutes()+10,01,01)

我知道这个话题太老了。但是我非常确定有一些开发人员仍然需要这个，所以我为您制作了这个简单的脚本。 希望你喜欢!
你好，现在是2020年，我做了一些修改，希望现在能更好地帮助你!
你好，现在是2022年，我又回来解决了一些问题，并为方法和函数提供了更好的命名。
function addTimeToDate(addedTime, date){ let generatedTime = date.getTime(); if(addedTime.seconds) generatedTime += 1000 * addedTime.seconds; //check for additional seconds if(addedTime.minutes) generatedTime += 1000* 60 * addedTime.minutes;//check for additional minutes if(addedTime.hours) generatedTime += 1000 * 60 * 60 * addedTime.hours;//check for additional hours return new Date(generatedTime); } Date.prototype.addTime = function(addedTime){ return addTimeToDate(addedTime, this); } let futureDate = new Date().addTime({ hours: 16, //Adding one hour minutes: 45, //Adding fourty five minutes seconds: 0 //Adding 0 seconds return to not adding any second so we can remove it. }); <button onclick="console.log(futureDate)">Travel to the future</button>
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;
};
var myDate= new Date();
var MyNewDate = new Date
(myDate.getFullYear(),myDate.getMonth(),myDate.getDate(),myDate.getMinutes()+10,01,01)
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'));
您应该获取当前日期的值以获得日期(ms)，并向其添加(30 * 60 *1000)。现在你有(当前日期+ 30分钟)ms
console.log('with ms'， Date.now() + (30 * 60 * 1000)) console.log('new Date'， new Date(Date.now() + (30 * 60 * 1000)))
