这个文档提到了时刻。ISO_8601作为格式化选项(从2.7.0 - http://momentjs.com/docs/#/parsing/special-formats/)，但这些都不能工作(即使是2.7.0):
var date = moment();
date.format(moment.ISO_8601); // error
moment.format(date, moment.ISO_8601); // error
(http://jsfiddle.net/b3d6uy05/1/)
如何从moment.js中获得ISO 8601 ?
当前回答
var date = moment(new Date(), moment.ISO_8601);
console.log(date);
其他回答
使用不带参数的格式:
var date = moment();
date.format(); // "2014-09-08T08:02:17-05:00"
(http://jsfiddle.net/8gvhL1dz/)
moment().toISOString(); // or format() - see below
http://momentjs.com/docs/#/displaying/as-iso-string/
Update Based on the answer: by @sennet and the comment by @dvlsg (see Fiddle) it should be noted that there is a difference between format and toISOString. Both are correct but the underlying process differs. toISOString converts 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, format uses the default format (YYYY-MM-DDTHH:mm:ssZ) without milliseconds and maintains the timezone offset.
我开了一个问题，因为我认为它会导致意想不到的结果。
var date = moment(new Date(), moment.ISO_8601);
console.log(date);
当你使用Mongoose将日期存储到MongoDB时，你需要使用toISOString()，因为所有的日期都存储为以毫秒为单位的ISOdates。
moment.format()
2018-04-17T20:00:00Z
moment.toISOString() -> USE THIS TO STORE IN MONGOOSE
2018-04-17T20:00:00.000Z
如果需要格式化字符串:YYYY-MM-DDTHH:mm:ssZ
var date = moment();
console.log(date.format("YYYY-MM-DDTHH:mm:ssZ"));
