如何在angular 9中设置对象模型中的数组属性

export class User {
  name: string;
  age: number;
  hobbies: string[];
}

import { Component } from '@angular/core';
import { User } from './user.model';

@Component({
  selector: 'app-user',
  templateUrl: './user.component.html',
  styleUrls: ['./user.component.css']
})
export class UserComponent {
  user: User;

  constructor() {
    this.user = new User();
    this.user.hobbies = [];
  }
}

<label for="hobbies">Hobbies:</label>
<input type="text" id="hobbies" [(ngModel)]="user.hobbies" name="hobbies">

import { Component } from '@angular/core';
import { User } from './user.model';

@Component({
  selector: 'app-user',
  templateUrl: './user.component.html',
  styleUrls: ['./user.component.css']
})
export class UserComponent {
  user: User;

  constructor() {
    this.user = new User();
    this.user.hobbies = [];
  }

  saveUser() {
    console.log(this.user.hobbies); // 打印用户输入的hobbies
    // 其他保存用户的逻辑...
  }
}
