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>

没有实用程序的一行程序:

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

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'));

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

以下是ES6版本:

let getTimeAfter30Mins = () => {
  let timeAfter30Mins = new Date();
  timeAfter30Mins = new Date(timeAfter30Mins.setMinutes(timeAfter30Mins.getMinutes() + 30));
};

这样称呼它:

getTimeAfter30Mins();

一行代码

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

在哪里分钟是一个数字
