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

另一种格式化日期的方法

new Date().toLocaleString('en-us',{month:'long', year:'numeric', day:'numeric'}) //output: "May 21, 2019"

如果你不想使用一个外部库，或者存储一个月份名称的数组，或者如果ECMAScript国际化API因为浏览器兼容性而不够好，你可以通过从日期输出中提取信息来实现:

var now = new Date();
var monthAbbrvName = now.toDateString().substring(4, 7);

这将为您提供缩写的月份名称，例如october。我相信日期将以各种格式出现，这取决于初始化和您的地区，因此请查看toDateString()返回的内容，并基于此重新计算您的substring()值。

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

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.

您可以使用几种可用的日期格式化程序之一。因为这属于JavaScript规范，所以它可以在浏览器和服务器端模式下使用。

objDate.toString().split(" ")[1]; // gives short name, unsure about locale 
objDate.toLocaleDateString.split(" ")[0]; // gives long name

e.g.

js> objDate = new Date(new Date() - 9876543210)
Mon Feb 04 2013 12:37:09 GMT-0800 (PST)
js> objDate.toString().split(" ")[1]
Feb
js> objDate.toLocaleString().split(" ")[0]
February
