Adding minutes to datetime in momentjs
提问by CsharpBeginner
I need to add the variable secondsToMinutesto the startdate.
我需要将变量添加secondsToMinutes到startdate.
secondsToMinutesis "3:20"
startDate= "2:00 PM"
endDateshould equal "2:03:20 PM".
I've tried a number of ways and get errors each and every time.
secondsToMinutes是“3:20”
startDate=“2:00 PM”
endDate应该等于“2:03:20 PM”。我尝试了多种方法，但每次都会出错。
var startdate = data.StartTime;
startdate = moment(startdate).format('LTS');
var secondsToMinutes = readableDuration(self.runlength());//='3:20';
var seconds = secondsToMinutes.split(':')[1];
var minutes = secondsToMinutes.split(':')[0];
var date = moment(startdate)
.add(seconds, 'seconds')
.add(minutes, 'minutes')
.format('LTS');
Date shows up as invalid date.
日期显示为无效日期。

moment().format("LTS")returns a string value in hh:mm:ss AM/PMformat.
When you create a moment object using a string that is not in standard format, you should pass the input format as second parameter to moment constructor.
moment().format("LTS")以hh:mm:ss AM/PM格式返回字符串值。当您使用非标准格式的字符串创建 moment 对象时，您应该将输入格式作为第二个参数传递给 moment 构造函数。
For eg: Jan 1, 2017in string 01012017is not a standard representation. But if you need a moment object out of it, using moment("01012017")will give "Invalid Date" response when formatting. Instead, use moment("01012017","DDMMYYYY")
例如：Jan 1, 2017in string01012017不是标准表示。但是如果你需要一个 moment 对象，使用它moment("01012017")会在格式化时给出“无效日期”响应。相反，使用moment("01012017","DDMMYYYY")
var d = moment("01012017")
d.toISOString() => "Invalid date"
var d = moment("01012017", "DDMMYYYY")
d.toISOString() => "2016-12-31T18:30:00.000Z"
In your code, when creating 'date' variable pass "hh:mm:ss A" as second parameter in the moment constructor as mentioned below .
在您的代码中，创建 'date' 变量时，将“hh:mm:ss A”作为构造函数中的第二个参数传递，如下所述。
var date = moment(startdate, "hh:mm:ss A")
.add(seconds, 'seconds')
.add(minutes, 'minutes')
.format('LTS');

Moment has really good documentation. I would check it out: http://momentjs.com/docs/
Moment 有非常好的文档。我会检查一下：http: //momentjs.com/docs/
But to address your question more directly, you coulddo something like:
但要更直接地解决您的问题，您可以执行以下操作：
var secondsToMinutes = '3:20';
var seconds = secondsToMinutes.split(':')[1];
var minutes = secondsToMinutes.split(':')[0];
var momentInTime = moment(...)
.add(seconds,'seconds')
.add(minutes,'minutes')
.format('LT');
You should use the actual handlers to the best of your ability. There are some cool things you can do with durations now, but this is more succinct.
您应该尽最大努力使用实际的处理程序。现在你可以用持续时间做一些很酷的事情，但这更简洁。

As mentioned in a different answer:
正如在不同的答案中提到的：
moment('2:00:00 PM', 'h:mm:ss A')
Is necessary if you're handling thatformat. Regardless - adding/subtracting minutes/hours to a moment object is trivial. Passing invalid strings to a moment object is a different issue in-and-of itself. ;)
如果您正在处理该格式，则这是必要的。无论如何 - 为时刻对象添加/减去分钟/小时是微不足道的。将无效字符串传递给 moment 对象本身就是一个不同的问题。;)

In the last moment()call you're trying to parse the value '2:00:00 PM'. According to the docs you have to use String+Format call in this case:
在最后一次moment()调用中，您试图解析值“2:00:00 PM”。根据文档，在这种情况下您必须使用 String+Format 调用：
For consistent results parsing anything other than ISO 8601 strings, you should use String + Format.
对于解析除 ISO 8601 字符串以外的任何内容的一致结果，您应该使用字符串 + 格式。
When you do:
当你这样做时：
var date = moment('2:00:00 PM')
.add(30, 'seconds')
.add(2, 'minutes')
.format('LTS');
The datewill be an Invalid date. But if you pass format h:mm:ss Aas a second parameter:
该date会是一个Invalid date。但是，如果您将格式h:mm:ss A作为第二个参数传递：
var date = moment('2:00:00 PM', 'h:mm:ss A')
.add(30, 'seconds')
.add(2, 'minutes')
.format('LTS');
... the result is 2:02:30 PM.
……结果是2:02:30 PM。
