Moment js Time Ago 计算错误的日期

Question

也许是一个简单的问题，但我不明白。

var date = new Date();
test = date.toISOString();
alert(moment(test, "YYYYMMDD").fromNow());

会return“16小时”，但为什么？

Answer 1

因为您正在使用 moment(String, String), instead of moment(String) (toISOString() output is obviously in ISO 8601 format) or moment(Date).

所以 moment(test, "YYYYMMDD") 将是一天的开始而不是当前时间。

如 Default 部分所述：

You can create a moment object specifying only some of the units, and the rest will be defaulted to the current day, month or year, or 0 for hours, minutes, seconds and milliseconds.

var date = new Date();
test = date.toISOString();
var m1 = moment(test, "YYYYMMDD")
console.log(m1.format());
console.log(m1.fromNow());
var m2 = moment(test)
console.log(m2.format());
console.log(m2.fromNow());
var m3 = moment(date)
console.log(m3.format());
console.log(m3.fromNow());
