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>

var myDate= new Date();
var MyNewDate = new Date 
(myDate.getFullYear(),myDate.getMonth(),myDate.getDate(),myDate.getMinutes()+10,01,01)

一行代码

  var afterSomeMinutes = new Date(new Date().getTime() + minutes * 60000);

在哪里分钟是一个数字

var add_minutes =  function (dt, minutes) {
return new Date(dt.getTime() + minutes*60000);
}
 console.log(add_minutes(new Date(2014,10,2), 30).toString());

使用已知的现有库来处理处理时间计算所涉及的异常。我现在最喜欢的是moment.js。

<script src="//cdnjs.cloudflare.com/ajax/libs/moment.js/2.13.0/moment.js"></script>
<script>
 var now = moment(); // get "now"
 console.log(now.toDate()); // show original date
 var thirty = moment(now).add(30,"minutes"); // clone "now" object and add 30 minutes, taking into account weirdness like crossing DST boundries or leap-days, -minutes, -seconds.
 console.log(thirty.toDate()); // show new date
</script>
