我的日期选取器组件代码：

• 模板代码：

第一个月

• component.ts

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

@Component({
  selector: 'app-date-picker',
  templateUrl: './date-picker.component.html',
  styleUrls: ['./date-picker.component.scss']
})
export class DatePickerComponent implements OnInit {

  model: NgbDateStruct;
  date: {year: number, month: number};

  constructor(private calendar: NgbCalendar) {
  }

  ngOnInit(): void {
  }
}
