我正在嘗試為反應(yīng)形式構(gòu)建一個(gè)可重用的字段組件，但我無法從custom-input組件中獲取值。<form [formGroup]="form" (ngSubmit)="submit()">  <custom-input id="name" name="name" formControlName="name"></custom-input>  <button type="submit" name="button">Submit</button></form>我的自定義輸入可重用組件import { Component, OnInit, Input } from '@angular/core';import { FormControl } from "@angular/forms";@Component({  selector: 'custom-input',  template: '<input type="text" [class]="class" [id]="id" [name]="name" [formControlName]="formControlName">',  styles: []})export class CustomInputComponent implements OnInit {  @Input() public id: string;  @Input() public class: string;  @Input() public name: string;  @Input() public formControlName: string;  constructor() { }  ngOnInit() {  }}
