角度错误TypeError：无法设置未定义的属性“名称”

Question

我正在尝试从表单中获取值，但是我一直在收到此错误。这是代码。我的formControlName是值的“名称”，并且我试图将其放在我创建的类Address类型的变量中。变量是newAddress，表单组是addressForm。这是我要尝试实现的功能，这是我的Address类。

onSubmit() {
    this.newAddress.name = this.addressForm.value['name'];
    console.log(this.newAddress.name);
    this.addressForm.reset({
      name: '',
      addressLine1: '',
      city: '',
      state: '',
      zipcode: '',
     });
      this.addressFormDirective.resetForm();
  }

export class Address {
    name: string;
    addressLine1: string;
    city: string;
    state: string;
    zipcode: string;
}

首先在构造函数中将其初始化

this.newAddress=new Address()
