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

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);

如果您不介意扩展Date原型(并且有一些很好的理由不想这样做),您实际上可以提出一个非常简单的方法:

Date.prototype.monthNames = [
    "January", "February", "March",
    "April", "May", "June",
    "July", "August", "September",
    "October", "November", "December"
];

Date.prototype.getMonthName = function() {
    return this.monthNames[this.getMonth()];
};
Date.prototype.getShortMonthName = function () {
    return this.getMonthName().substr(0, 3);
};

// usage:
var d = new Date();
alert(d.getMonthName());      // "October"
alert(d.getShortMonthName()); // "Oct"

这些函数将应用于所有javascript Date对象。

只需要编写一个简单的toLocaleString包装器:

函数 LocalDate(locale) { this.locale = locale; } LocalDate.prototype.getMonthName = function(date) { return date.toLocaleString(this.locale,{month:“long”}); }; var objDate = new Date(“10/11/2009”); var localDate = new LocalDate(“en”); console.log(localDate.getMonthName(objDate)); localdate.locale = “ru”; console.log(localDate.getMonthName(objDate)); localdate.locale = “zh”; console.log(localDate.getMonthName(objDate));

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"]

我的最佳解决方案如下:

       var dateValue = Date();
       var month = dateValue.substring(4,7);
       var date = dateValue.substring(8,10);
       var year = dateValue.substring(20,24);
       var finaldateString = date+"-"+month+"-"+year;

你可以使用或不使用当地语言翻译

创造价值“2009年10月11日”

const objDate =新日期("10/11/2009"); const月=[‘简’,2月,3月,4月,“可能”,“君”,7月,8月,9月,10月,11月,12月的) if (objDate !== '无效日期' && !isNaN(objDate)) { console.log(objDate.getDate() + ' ' + months[objDate.getMonth()] + ' ' + objDate.getFullYear())) }

ECMAScript国际化API将month转换为本地语言(例如:october 11)

const convertDate = new Date('10/11/2009') Const lang = 'fr' // de, es, ch if (convertDate !== '无效日期' && !isNaN(convertDate)) { console.log(convertDate. getdate () + ' ' + convertDate. log)toLocaleString(朗,{ 月:“长” })) }
