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

对我来说，这是最佳解，

对于TypeScript也一样

const env = process.env.REACT_APP_LOCALE || 'en';

const namedMonthsArray = (index?: number): string[] | string => {
  const months = [];

  for (let month = 0; month <= 11; month++) {
    months.push(
      new Date(new Date('1970-01-01').setMonth(month))
        .toLocaleString(env, {
          month: 'long',
        })
        .toString(),
    );
  }
  if (index) {
    return months[index];
  }
  return months;
};

输出是

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

如果您不介意扩展Date原型(并且有一些很好的理由不想这样做)，您实际上可以提出一个非常简单的方法:

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

Date.prototype.getMonthName = function() {
    return this.monthNames[this.getMonth()];
};
Date.prototype.getShortMonthName = function () {
    return this.getMonthName().substr(0, 3);
};

// usage:
var d = new Date();
alert(d.getMonthName());      // "October"
alert(d.getShortMonthName()); // "Oct"

这些函数将应用于所有javascript Date对象。

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

我的最佳解决方案如下:

       var dateValue = Date();
       var month = dateValue.substring(4,7);
       var date = dateValue.substring(8,10);
       var year = dateValue.substring(20,24);
       var finaldateString = date+"-"+month+"-"+year;
