如何在使用angular8启用提交按钮的情况下按enter键时启用搜索按钮

<input type="text" (keydown.enter)="search()" />
<button id="submitBtn" (click)="submit()">提交</button>
<button id="searchBtn" (click)="search()">搜索</button>

import { Component, ViewChild, ElementRef } from '@angular/core';

@Component({
  selector: 'app-search',
  templateUrl: './search.component.html',
  styleUrls: ['./search.component.css']
})
export class SearchComponent {
  @ViewChild('searchBtn') searchButton: ElementRef;

  ngAfterViewInit() {
    this.searchButton.nativeElement.disabled = true;
    document.addEventListener('keydown', (event) => {
      if (event.key === 'Enter') {
        this.searchButton.nativeElement.disabled = false;
      }
    });
  }

  search() {
    // 执行搜索操作
  }

  submit() {
    // 执行提交操作
  }
}
