角度2应用程序无法在ie / edge中工作

Question

我不知道为什么app不能正常工作。应用程序在chrome和firefox中工作得很好。即/ edge不显示日期。这是默认的教程角度2应用程序没有修改。我的英语。

import { Component } from '@angular/core'

@Component({
  selector: 'my-app',
  template: `
    <h1>My First Angular App</h1>

    <button (click)="showCurrentMonth()">Show Month</button>
    <span *ngIf="curentMonth">{{curentMonth}}</span>
    <br/>
    <button (click)="showCurrentcurentDate()">Show Date</button>
    <span *ngIf="curentDate">{{curentDate}}</span>
    `
})

export class AppComponent {
  splitedDate: string[] = new Date().toLocaleDateString().split(".");
  curentMonth: string;
  curentDate: Date;
  months = [
    "January","February","March","April",
    "May","June","July","August",
    "September","October","November","December"
  ]
  showCurrentMonth() {
    // udefined in IE/Edge
    this.curentMonth = this.months[parseInt(this.splitedDate[1]) - 1] 
  }
  showCurrentcurentDate() {
    var splitedcurrentDate: number[] = new Date()
       .toLocaleDateString()
       .split(".")
       .map(d => parseInt(d, 10))
    // invalid Date in IE/Edge
    this.curentDate = new Date(splitedcurrentDate[2], splitedcurrentDate[1],  splitedcurrentDate[0]) 
   }
}
