How do I format a date as ISO 8601 in moment.js?
提问by sennett
This docs mention moment.ISO_8601as a formatting option (from 2.7.0 - http://momentjs.com/docs/#/parsing/special-formats/), but neither of these work (even 2.7.0):
这个文档提到moment.ISO_8601了一个格式化选项（从 2.7.0 - http://momentjs.com/docs/#/parsing/special-formats/），但这些都不起作用（甚至 2.7.0）：
var date = moment();
date.format(moment.ISO_8601); // error
moment.format(date, moment.ISO_8601); // error

How can I get an ISO 8601 from moment.js?

moment().toISOString(); // or format() - see below

UpdateBased on the answer: by @sennet and the comment by @dvlsg (see Fiddle) it should be noted that there is a difference between formatand toISOString. Both are correct but the underlying process differs. toISOStringconverts to a Date object, sets to UTC then uses the native Date prototype function to output ISO8601 in UTC with milliseconds (YYYY-MM-DD[T]HH:mm:ss.SSS[Z]). On the other hand, formatuses the default format (YYYY-MM-DDTHH:mm:ssZ) without milliseconds and maintains the timezone offset.
更新根据答案：@sennet 和@dvlsg 的评论（参见Fiddle），应该注意的是format和之间存在差异toISOString。两者都是正确的，但底层过程不同。toISOString转换为 Date 对象，设置为 UTC，然后使用本机 Date 原型函数以毫秒 ( YYYY-MM-DD[T]HH:mm:ss.SSS[Z])输出 UTC 格式的 ISO8601 。另一方面，format使用YYYY-MM-DDTHH:mm:ssZ没有毫秒的默认格式 ( ) 并保持时区偏移。
I've opened an issueas I think it can lead to unexpected results.
我打开了一个问题，因为我认为它会导致意想不到的结果。

Use formatwith no parameters:
format不带参数使用：
var date = moment();
date.format(); // "2014-09-08T08:02:17-05:00"

Also possible with vanilla JS
也可以使用 vanilla JS
new Date().toISOString() // "2017-08-26T16:31:02.349Z"

When you use Mongoose to store dates into MongoDB you need to use toISOString() because all dates are stored as ISOdates with miliseconds.
当您使用 Mongoose 将日期存储到 MongoDB 时，您需要使用 toISOString()，因为所有日期都存储为 ISOdates，以毫秒为单位。
moment.format()
2018-04-17T20:00:00Z
moment.toISOString() -> USE THIS TO STORE IN MONGOOSE
2018-04-17T20:00:00.000Z

If you just want the date portion (e.g. 2017-06-27), and you want it to work regardless of time zone and also in Arabic, here is code I wrote:
如果您只想要日期部分（例如 2017-06-27），并且您希望它不受时区和阿拉伯语的影响，这里是我写的代码：
function isoDate(date) {
if (!date) {
return null
}
date = moment(date).toDate()
// don't call toISOString because it takes the time zone into
// account which we don't want. Also don't call .format() because it
// returns Arabic instead of English
var month = 1 + date.getMonth()
if (month < 10) {
month = '0' + month
}
var day = date.getDate()
if (day < 10) {
day = '0' + day
}
return date.getFullYear() + '-' + month + '-' + day
}

var x = moment();
//date.format(moment.ISO_8601); // error
moment("2010-01-01T05:06:07", ["YYYY", moment.ISO_8601]);; // error
document.write(x);
