在IE10中将日历更改为法语时出现问题

Question

我在我的web应用中使用了两个日期选择器，通过选择开始日期和结束日期来过滤数据。我使用mat-datepicker of Angular Material。

我必须用法语显示日历，所以我使用了以下代码：

constructor(private dateAdapter: DateAdapter<Date>) {
    // Change calendar to french version
    this.dateAdapter.setLocale('fr');
}

这在chrome和mozilla中工作得很好。但在IE10中，我的日历仍然是英文的。截图如下：

以下是我的pollyfill.ts内容：

.....
import 'core-js/es6/symbol';
import 'core-js/es6/object';
import 'core-js/es6/function';
import 'core-js/es6/parse-int';
import 'core-js/es6/parse-float';
import 'core-js/es6/number';
import 'core-js/es6/math';
import 'core-js/es6/string';
import 'core-js/es6/date';
import 'core-js/es6/array';
import 'core-js/es6/regexp';
import 'core-js/es6/map';
import 'core-js/es6/weak-map';
import 'core-js/es6/set';

import 'core-js/es7/symbol';
import 'core-js/es7/object';
import 'core-js/es7/math';
import 'core-js/es7/string';
import 'core-js/es7/array';
import 'core-js/es7/map';
import 'core-js/es7/weak-map';
import 'core-js/es7/set';
import 'web-animations-js';  // Run `npm install --save web-animations-js`.
import 'zone.js/dist/zone';  // Included with Angular CLI.

根据Material Datepicker document，我使用以下代码创建了一个示例，它在IE10中运行良好，你可以参考它：

Component.ts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';

import * as _moment from 'moment';
// tslint:disable-next-line:no-duplicate-imports
//import {default as _rollupMoment} from 'moment';

const moment =  _moment;

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

@Component({
  selector: 'app-material-datepicker',
  templateUrl: 'material-datepicker.component.html',
  styleUrls: ['material-datepicker.component.css'],
  providers: [
    {provide: DateAdapter, useClass: MomentDateAdapter, deps: [MAT_DATE_LOCALE]},

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

  constructor(private adapter: DateAdapter<Date>) {
    this.adapter.setLocale('fr');
  }
  date = new FormControl(moment());
}

Conponent.html中的代码：

<mat-form-field>
  <input matInput [matDatepicker]="dp" placeholder="Verbose datepicker" [formControl]="date">
  <mat-datepicker-toggle matSuffix [for]="dp"></mat-datepicker-toggle>
  <mat-datepicker #dp></mat-datepicker>
</mat-form-field>

package.json：

{
  "name": "angular-material-sample",
  "version": "0.0.0",
  "scripts": {
    "ng": "ng",
    "start": "ng serve",

    "zone.js": "~0.8.26"
  },
  "devDependencies": {
    "@angular-devkit/build-angular": "~0.11.0",
    "@angular/cli": "~7.1.4",
    "@angular/compiler-cli": "~7.1.0",
    "@angular/language-service": "~7.1.0",
    "@types/node": "~8.9.4",
    "@types/jasmine": "~2.8.8",
    "@types/jasminewd2": "~2.0.3",

    "jasmine-spec-reporter": "~4.2.1",
    "karma": "~3.1.1",
    "karma-chrome-launcher": "~2.2.0",

    "ts-node": "~7.0.0",
    "tslint": "~5.11.0",
    "typescript": "~3.1.6"
  }
}

然后，结果如下：
