你可以试试这个:

let d = new Date()， t = d.toDateString()。分割(" "); Console.log (t[2] + " " + t[1] + " " + t[3]);

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.

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'

我们不需要声明一个包含所有月份名称的数组，然后用一个索引来指向，我们也可以把它写成一个简短的版本，如下所示:

var objDate = new Date().toLocaleString("en-us", { month: "long" }); // result: August
var objDate = new Date().toLocaleString("en-us", { month: "short" }); // result: Aug

只是扩展了许多其他优秀的答案-如果你正在使用jQuery -你可以做一些类似的事情

$.fn.getMonthName = function(date) {

    var monthNames = [
    "January", "February", "March",
    "April", "May", "June",
    "July", "August", "September",
    "October", "November", "December"
    ];

    return monthNames[date.getMonth()];

};

其中date等于var d = new date (somevalue)。这样做的主要优点是@nickf避免使用全局名称空间。

如果我们需要传递输入，那么我们需要使用以下方式

输入:“2020-12-28”

代码:

new Date('2020-12-28').toLocaleString('en-us',{month:'short', year:'numeric'})

输出:“2020年12月”
