文档。写(新日期()。toLocaleString('en-us'，{月:'长'，年:'数字'，日:'数字'}))

将名称存储在一个数组中，并根据月份的索引进行查找。

var month=new Array(12);
month[0]="January";
month[1]="February";
month[2]="March";
month[3]="April";
month[4]="May";
month[5]="June";
month[6]="July";
month[7]="August";
month[8]="September";
month[9]="October";
month[10]="November";
month[11]="December";

document.write("The current month is " + month[d.getMonth()]);

JavaScript getMonth()方法

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。

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.

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"]

也可以这样做:

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