javascript - 如何在 javascript 中将天数添加到日期时间？

Question

我有日期和时间格式 datetimepicker。我想为日期时间添加天数

inputdattime 将从 datetimepicker 中选取

input datetime = Friday, October 23rd 2015, 12:00:00 am
 output should be if i add 2 days sunday, oct 25 2015 12:00:00 am

如何做到这一点

var deal_from_date = new Date();
var numberOfDaysToAdd  = 7;
 var date1 = deal_from_date.setDate(deal_from_date.getDate() + numberOfDaysToAdd);

实际输出应该是

"dddd, MMMM Do YYYY, h: mm:ss a"
 Sun Oct 25 2015 12:00:00

当前输出是:

     Sun Oct 25 2015 12:54:06

Answer 1

setDate() 方法可用于向日期添加天数

var today=new Date('23/10/2015');
var in_a_day=new Date(today).setDate(today.getDate()+2);

试试这段代码:-

var d = new Date('oct 25 2015 12:00:00 pm');
d.setDate(d.getDate() + 2)
alert(d);

output is :- Tue Oct 27 2015 12:00:00 GMT+0530 (IST)
