如何在JavaScript中从这个日期对象生成月份的名称(例如:10月/ 10月)?

var objDate = new Date("10/11/2009");

当前回答

我用了一个很有效的小窍门:

const monthNumber = 8; const yearNumber = 2018; const date = ' ${['Jan', 'Feb', 'Mar', 'Apr', “五月”,“六月”,“七月”,“八月”, 'Sep', 'Oct', 'Nov', 'Dec'][monthNumber - 1] } $ {yearNumber} '; console.log(日期);

如果您不想使用时刻,并希望显示月份名称-

.config($mdDateLocaleProvider) {
    $mdDateLocaleProvider.formatDate = function(date) {      
      if(date !== null) {
        if(date.getMonthName == undefined) {
          date.getMonthName = function() {
            var monthNames = [ "January", "February", "March", "April", "May", "June", 
            "July", "August", "September", "October", "November", "December" ];
            return monthNames[this.getMonth()];
          }
        }        
        var day = date.getDate();
        var monthIndex = date.getMonth();
        var year = date.getFullYear();
        return day + ' ' + date.getMonthName() + ' ' + year;
      }
    };
  }

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: [...]};

不幸的是,提取月份名称的最佳方法是从UTCString表示中提取:

Date.prototype.monthName = function() {
    return this.toUTCString().split(' ')[2]
};

d = new Date();
//=> Thu Mar 06 2014 23:05:21 GMT+0000 (GMT)

d.monthName();
//=> 'Mar'

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"]
