moment.js 日期包装类

Moment.js

1创建时间对象

moment(); 当前时间

moment(new Date(2020, 3, 7)); date 对象创建

moment(1318781876406); 时间戳创建

moment("12-25-1995", "MM-DD-YYYY"); 日期文字+日期格式

moment("12-25-1995", ["MM-DD-YYYY", "YYYY-MM-DD"]);

moment([year, month , date , hours , minutes , seconds , milliseconds ]); 数组创建

moment.unix(Number)　　　　　　　　　　　　　　 unix时间

2 修改时间对象

2.1 加减

moment().add(1000) 加毫秒

moment().add('days', 7) 加7天

moment().subtract('days', 7); 减7天

moment().add({days:-7,months:1}); 加1月，减7天

2.2设值

moment().seconds(30); year/month/date/day/minutes/seconds 方法

moment().seconds(); 取值

设首/尾

moment().startOf('year'); // set to Jan 1 12:00:00.000 pm this year

moment().startOf('month'); // set to the first of this month, 12:00:00.000 pm

moment().startOf('day'); // set to 12:00:00.000 pm today

moment().startOf('hour'); // set to now, but with 0 mins, 0 secs, and 0 ms

moment().startOf('minute'); // set to now, but with 0 seconds and 0 milliseconds

moment().startOf('second'); // same as moment().milliseconds(0);

moment().endOf('year');

moment().sod(); 当天头

moment().eod(); 当天尾

4 比较

var a = moment([2007, 0, 29]);

var b = moment([2007, 0, 28]);

a.diff(b, 'days') // 1

5 汉化

moment.lang('zh-cn', {

months : "一月_二月_三月_四月_五月_六月_七月_八月_九月_十月_十一月_十二月".split("_"),

monthsShort : "1月_2月_3月_4月_5月_6月_7月_8月_9月_10月_11月_12月".split("_"),

}

calendar : {

sameElse : 'L'

relativeTime : {
