如何国际化 ng-bootstrap datepicker？

Question

在我的项目中，我使用ng-bootstrap datePicker。我的 datePicker 小部件非常简单：DEMO。

但我需要将他的国际化（需要设置俄语）。请帮我。

js:

import {Component} from '@angular/core';
import {NgbDate, NgbCalendar} from '@ng-bootstrap/ng-bootstrap';

@Component({
  selector: 'ngbd-datepicker-range',
  templateUrl: './datepicker-range.html',
  styles: [``]
})
export class NgbdDatepickerRange {

  hoveredDate: NgbDate;

  fromDate: NgbDate;
  toDate: NgbDate;

  constructor(calendar: NgbCalendar) {
    this.fromDate = calendar.getToday();
    this.toDate = calendar.getNext(calendar.getToday(), 'd', 10);
  }

  onDateSelection(date: NgbDate) {
    if (!this.fromDate && !this.toDate) {
      this.fromDate = date;
    } else if (this.fromDate && !this.toDate && date.after(this.fromDate)) {
      this.toDate = date;
    } else {
      this.toDate = null;
      this.fromDate = date;
    }
  }

  isHovered = (date: NgbDate) => this.fromDate && !this.toDate && this.hoveredDate && date.after(this.fromDate) && date.before(this.hoveredDate);
  isInside = (date: NgbDate) => date.after(this.fromDate) && date.before(this.toDate);
  isRange = (date: NgbDate) => date.equals(this.fromDate) || date.equals(this.toDate) || this.isInside(date) || this.isHovered(date)
}

好的，这里是解决方案：https://stackblitz.com/edit/angular-dd3vve ?file=app/datepicker-range.ts

我改变了什么（以这个演示为例）：

// now class extend NgbDatepickerI18n
export class NgbdDatepickerRange extends NgbDatepickerI18n {

。

// call to super() in constructor
constructor(calendar: NgbCalendar) {
  super()

。

// implement the abstract methods
getWeekdayShortName(weekday: number): string {return "td"};
getMonthShortName(month: number): string {return "mt"};
getMonthFullName(month: number): string {return "month"};
getDayAriaLabel(date: NgbDateStruct): string {return "e"};

。

// provide in component
@Component({
  selector: 'ngbd-datepicker-range',
  templateUrl: './datepicker-range.html',
  providers: [{provide: NgbDatepickerI18n, useClass: NgbdDatepickerRange}],

您需要更改方法以返回可用值

您可以简单地使用：

import { LOCALE_ID } from '@angular/core';
import { registerLocaleData } from "@angular/common";
import localeRo from "@angular/common/locales/ro";
import localeRoExtra from "@angular/common/locales/extra/ro";

registerLocaleData(localeRo, "ro", localeRoExtra);

然后在 @NgModule 装饰器中使用提供程序：

providers: [{ provide: LOCALE_ID, useValue: "ro-RO"}]

没有必要NgbDatepickerI18n！
