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

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"]

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

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;
      }
    };
  }

文档。写(新日期()。toLocaleString('en-us',{月:'长',年:'数字',日:'数字'}))

我是通过DatePipe完成的。

const datePipe = new DatePipe(this.locale);
datePipe.transform(myDate, 'MMM. y');

你可以像这样在构造函数中注入默认区域:

constructor(@Inject(LOCALE_ID) private locale: string){}

Angular的引用https://angular.io/api/common/DatePipe

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);
