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

我想到了一个部分解决方案。它使用正则表达式提取月份和日期名称。但当我查看区域和语言选项(窗口)时，我意识到不同的文化有不同的格式顺序……也许更好的正则表达式模式会有用。

function testDateInfo() {
        var months = new Array();
        var days = new Array();
        var workingDate = new Date();
        workingDate.setHours(0, 0, 0, 0);
        workingDate.setDate(1);
        var RE = new RegExp("([a-z]+)","ig");
        //-- get day names 0-6
        for (var i = 0; i < 7; i++) {

            var day = workingDate.getDay();
            //-- will eventually be in order
            if (days[day] == undefined)
                days[day] = workingDate.toLocaleDateString().match(RE)[0];
            workingDate.setDate(workingDate.getDate() + 1);
        }
        //--get month names 0-11
        for (var i = 0; i < 12; i++) {
            workingDate.setMonth(i);
            months.push(workingDate.toLocaleDateString().match(RE)[1]);
        }
        alert(days.join(",") + " \n\r " + months.join(","));
    }

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"]

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。

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
