提问by Takwa Chammam
I am trying to add two dates:
我正在尝试添加两个日期：
date start Fri Apr 26 2013 16:08:03 GMT+0100 (Paris, Madrid)
+
date periode Fri Apr 26 2013 00:10:00 GMT+0100 (Paris, Madrid)
I used this code:
我使用了这个代码：
var periode=$("#dure").val();
var start = $("#start").val()
var end =$("#end").val();
var dateStart= new Date(start);
console.log('start');
console.log(dateStart);
var date=dateStart.format('yyyy-mm-dd');
per=date+' '+periode;
var datePeriode= new Date(per);
console.log('datePeriode');
console.log(datePeriode);
var dateEnd= dateStart.getTime()+datePeriode.getTime();
console.log('dateEnd');
console.log(dateEnd);
In my JavaScript console, I get:
在我的 JavaScript 控制台中，我得到：
dateDebut
Fri Apr 26 2013 16:33:11 GMT+0100 (Paris, Madrid)
datePeriode
Fri Apr 26 2013 00:15:00 GMT+0100 (Paris, Madrid)
dateEnd
2733922091000
How can I fix that? Am I missing something?
我该如何解决？我错过了什么吗？

If you want to add a time period to a date, you basically have to convert both of them into milliseconds.
如果要为日期添加时间段，则基本上必须将它们都转换为毫秒。
var date = new Date();
var dateMillis = date.getTime();
//JavaScript doesn't have a "time period" object, so I'm assuming you get it as a string
var timePeriod = "00:15:00"; //I assume this is 15 minutes, so the format is HH:MM:SS
var parts = timePeriod.split(/:/);
var timePeriodMillis = (parseInt(parts[0], 10) * 60 * 60 * 1000) +
(parseInt(parts[1], 10) * 60 * 1000) +
(parseInt(parts[2], 10) * 1000);
var newDate = new Date();
newDate.setTime(dateMillis + timePeriodMillis);
console.log(date); //eg: Fri Apr 26 2013 08:52:50 GMT-0700 (MST)
console.log(newDate); //eg: Fri Apr 26 2013 09:07:50 GMT-0700 (MST)

Convert datePeriod to milliseconds instead of making it into a date object for your addition.
将 datePeriod 转换为毫秒，而不是将其转换为用于添加的日期对象。
You need to convert the sum to a date. getTime()is in milliseconds since 1-1-1970. So you want to do.
您需要将总和转换为日期。 getTime()自 1-1-1970 以来的毫秒数。所以你想做。
var ending = new Date();
ending.setTime(dateEnd);
console.log(ending);
setTimewill set the date properly for you.
setTime将为您正确设置日期。
