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

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"]

这是另一个，支持本地化:)

Date.prototype.getMonthName = function(lang) {
    lang = lang && (lang in Date.locale) ? lang : 'en';
    return Date.locale[lang].month_names[this.getMonth()];
};

Date.prototype.getMonthNameShort = function(lang) {
    lang = lang && (lang in Date.locale) ? lang : 'en';
    return Date.locale[lang].month_names_short[this.getMonth()];
};

Date.locale = {
    en: {
       month_names: ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'],
       month_names_short: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    }
};

然后，您可以轻松地添加对其他语言的支持:

Date.locale.fr = {month_names: [...]};

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

在IE 11, Chrome, Firefox上测试

const dt = new Date(); Const locale = navigator。语言!= undefined ?导航器。[0]: navigator.language; const fullMonth = dt。toLocaleDateString(区域设置，{month: 'long'}); console.log (fullMonth);

这里是一个函数，你将1传递给12，并返回完整的月份名称例如" January "或" July "

    function getMonthName(monthNumber) {
      return new Date('1999-' + monthNumber + '-15').toLocaleString('en-us', { month: 'long' })
    }
