对于momentjs，只需使用格式符号。

const myDate = new Date()
const shortMonthName = moment(myDate).format('MMM') // Aug
const fullMonthName = moment(myDate).format('MMMM') // August

现在的自然格式是使用Moment.js。

在Moment.js中，以字符串格式获取月份的方法非常简单，不需要在代码中硬编码月份名称: 要获得当前月份和年份的月份名称格式和全年(2015年5月):

  moment(new Date).format("MMMM YYYY");

如果你使用剑道，也可以这样做。

kendo.toString(dateobject, "MMMM");

以下是kendo网站上的格式化器列表:

"d" Renders the day of the month, from 1 through 31. "dd" The day of the month, from 01 through 31. "ddd" The abbreviated name of the day of the week. "dddd" The full name of the day of the week. "f" The tenths of a second in a date and time value. "ff" The hundredths of a second in a date and time value. "fff" The milliseconds in a date and time value. "M" The month, from 1 through 12. "MM" The month, from 01 through 12. "MMM" The abbreviated name of the month. "MMMM" The full name of the month. "h" The hour, using a 12-hour clock from 1 to 12. "hh" The hour, using a 12-hour clock from 01 to 12. "H" The hour, using a 24-hour clock from 1 to 23. "HH" The hour, using a 24-hour clock from 01 to 23. "m" The minute, from 0 through 59. "mm" The minute, from 00 through 59. "s" The second, from 0 through 59. "ss" The second, from 00 through 59. "tt" The AM/PM designator. "yy" The last two characters from the year value. "yyyy" The year full value. "zzz" The local timezone when using formats to parse UTC date strings.

获取月份名称的数组:

Date.monthNames = function( ) {
var arrMonth = [],
    dateRef = new Date(),
    year = dateRef.getFullYear();

dateRef.setMonth(0);
while (year == dateRef.getFullYear()) {
    /* push le mois en lettre et passe au mois suivant */
    arrMonth.push( (dateRef.toLocaleString().split(' '))[2] );
    dateRef.setMonth( dateRef.getMonth() + 1);
}

return arrMonth;
}

alert(Date.monthNames().toString());

// -> janvier,février,mars,avril,mai,juin,juillet,août,septembre,octobre,novembre,décembre

这里是一个函数，你将1传递给12，并返回完整的月份名称例如" January "或" July "

    function getMonthName(monthNumber) {
      return new Date('1999-' + monthNumber + '-15').toLocaleString('en-us', { month: 'long' })
    }

不幸的是，提取月份名称的最佳方法是从UTCString表示中提取:

Date.prototype.monthName = function() {
    return this.toUTCString().split(' ')[2]
};

d = new Date();
//=> Thu Mar 06 2014 23:05:21 GMT+0000 (GMT)

d.monthName();
//=> 'Mar'
