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

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;
      }
    };
  }

其他回答

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

它可以被用作

var month_Name = new Date().getMonthName();

对于momentjs,只需使用格式符号。

const myDate = new Date()
const shortMonthName = moment(myDate).format('MMM') // Aug
const fullMonthName = moment(myDate).format('MMMM') // August

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));

也可以这样做:

var x = new Date().toString().split(' ')[1];    // "Jul"

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){}
