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");

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。

也可以这样做:

var x = new Date().toString().split(' ')[1];    // "Jul"

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

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.

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"
