Angular -如何通过Id自动填写表单

userData: any;

<input type="text" [(ngModel)]="userData.name" name="name">

import { Component } from '@angular/core';
import { HttpClient } from '@angular/common/http';

@Component({
  selector: 'app-form',
  templateUrl: './form.component.html',
  styleUrls: ['./form.component.css']
})
export class FormComponent {
  userData: any;

  constructor(private http: HttpClient) { }

  fetchUserDataById(userId: number) {
    this.http.get<any>('api/user/' + userId).subscribe(data => {
      this.userData = data;
    });
  }
}

ngOnInit() {
  const userId = 1; // 根据实际情况传入ID
  this.fetchUserDataById(userId);
}
