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"]

如果你赶时间……那就给你!

const date = new Date(Date.now());
date.toLocaleString('en-US', {month: 'short'}); // {month:'long'}

预期产出:“四月”

您可以使用datejs来实现这一点。检查格式说明符，MMMM给出了月份的名称:

var objDate = new Date("10/11/2009");
document.write(objDate.toString("MMMM"));

datejs本地化了超过150个locale !在这里看到的

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。

如果你正在使用jQuery，你可能也在使用jQuery UI，这意味着你可以使用$.datepicker. formatdate()。

$.datepicker.setDefaults( $.datepicker.regional[ "nl" ] );   // dutch
$.datepicker.formatDate( "dd MM yy", objDate );

date对象中一些常见的简单处理可以通过它来完成。

var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ]; var monthShortNames = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" ]; function dateFormat1(d) { var t = new Date(d); return t.getDate() + ' ' + monthNames[t.getMonth()] + ', ' + t.getFullYear(); } function dateFormat2(d) { var t = new Date(d); return t.getDate() + ' ' + monthShortNames[t.getMonth()] + ', ' + t.getFullYear(); } console.log(dateFormat1(new Date())) console.log(dateFormat2(new Date()))

或者你可以制作日期原型

Date.prototype.getMonthName = function() { var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ]; return monthNames[this.getMonth()]; } Date.prototype.getFormatDate = function() { var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ]; return this.getDate() + ' ' + monthNames[this.getMonth()] + ', ' + this.getFullYear(); } console.log(new Date().getMonthName()) console.log(new Date().getFormatDate())

Ex:

var dateentt3新日期()#发情

var dateFormat4 = new Date（）.getFormatDate（）;# 16 三月， 2017
