如何在IE浏览器的mat-datepicker中修复两位数的年份？

Question

在IE浏览器中，当我键入包含两位数字的日期时，例如: 03/12/17，mat-datepicker会将年份转换为03/12/1917。

我希望mat-datepicker将年份17转换为当前年份2017，例如，如果我输入03/12/17，则mat-datepicker应该将该日期转换为03/12/2017。

在Chrome浏览器中，mat-datepicker将两位数的年份正确地转换为17到2017年。

在IE浏览器中有解决这个问题的方法吗？

谢谢。

尝试使用以下代码：

html页面中的代码：

<mat-form-field>
  <input matInput [matDatepicker]="dp" placeholder="Month and Year" [formControl]="date">
  <mat-datepicker-toggle matSuffix [for]="dp"></mat-datepicker-toggle>
  <mat-datepicker #dp
                  startView="multi-year"
                  (yearSelected)="chosenYearHandler($event)"
                  (monthSelected)="chosenMonthHandler($event, dp)"
                  panelClass="example-month-picker">
  </mat-datepicker>
</mat-form-field>

.ts文件中的代码：

import {Component} from '@angular/core';
import {FormControl} from '@angular/forms';
import {MomentDateAdapter} from '@angular/material-moment-adapter';
import {DateAdapter, MAT_DATE_FORMATS, MAT_DATE_LOCALE} from '@angular/material/core';

// Depending on whether rollup is used, moment needs to be imported differently.
// Since Moment.js doesn't have a default export, we normally need to import using the `* as`
// syntax. However, rollup creates a synthetic default module and we thus need to import it using
// the `default as` syntax.
import * as _moment from 'moment';

const moment =  _moment;

export const MY_FORMATS = {
  parse: {
    dateInput: 'MM/DD/YYYY',
  },
  display: {
    dateInput: 'MM/DD/YYYY',
    monthYearLabel: 'MMM YYYY',
    dateA11yLabel: 'LL',
    monthYearA11yLabel: 'MMMM YYYY',
  },
};

@Component({
  selector: 'app-material-datepicker',
  templateUrl: 'material-datepicker.component.html',
  styleUrls: ['material-datepicker.component.css'],
  providers: [
    // `MomentDateAdapter` can be automatically provided by importing `MomentDateModule` in your
    // application's root module. We provide it at the component level here, due to limitations of
    // our example generation script.
    {provide: DateAdapter, useClass: MomentDateAdapter, deps: [MAT_DATE_LOCALE]},

    {provide: MAT_DATE_FORMATS, useValue: MY_FORMATS},
  ],
})
export class MaterialDatepickerComponent {

  constructor(private adapter: DateAdapter<Date>) {
  }
  date = new FormControl(moment());
}

然后，结果如下：
