其他解决方案:

var dateAv = new Date();
var endTime = new Date(dateAv.getFullYear(), dateAv.getMonth(), dateAv.getDate(), dateAv.getHours(), dateAv.getMinutes() + 30);
          

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

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));

也许像这样?

var d = new Date(); var v = new Date(); v.setMinutes (d.getMinutes () + 30); console.log (v)

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)))
