我有以下組件：import { Component, OnInit, Input, Output, EventEmitter } from '@angular/core';@Component({  selector: 'app-button',  styleUrls: ['./button.component.scss'],  template: `              <ion-button color="{{color}}" (click)="action.emit(null)" [disabled]="condition">                {{title}}              </ion-button>            `})export class ButtonComponent implements OnInit {  @Input() public title: string;  @Input() public color = 'primary';  @Input() public condition: any;  @Output() public action = new EventEmitter();  constructor() { }  ngOnInit() {  }}但是，當(dāng)我將布爾值傳遞出去時(shí)，它不會(huì)呈現(xiàn)，因?yàn)槲矣幸粋€(gè)布爾值，它以 false 開頭并根據(jù)輸入變?yōu)?true。編輯：問題是當(dāng) validDocument 變?yōu)?true 時(shí)，按鈕不會(huì)再次呈現(xiàn)并保持禁用狀態(tài)。HTML聲明：<app-button title="Buscar" (action)="go()" condition="!validDocument"></app-button>
