get of Map<string，string>不是Angualr测试中的函数

import { Component } from '@angular/core';
import { FormGroup, FormControl } from '@angular/forms';

@Component({
  selector: 'app-form',
  template: `
    <form [formGroup]="myForm">
      <input formControlName="name" placeholder="Name">
      <input formControlName="email" placeholder="Email">
    </form>
    <button (click)="submit()">Submit</button>
  `
})
export class FormComponent {
  myForm: FormGroup;

  constructor() {
    this.myForm = new FormGroup({
      name: new FormControl(''),
      email: new FormControl('')
    });
  }

  submit() {
    const name = this.myForm.get('name').value;
    const email = this.myForm.get('email').value;
    console.log('Name:', name);
    console.log('Email:', email);
  }
}
