Blogs[]2-克隆BlogComponent的最好方法: Angular to Navmenu combobox？

<!-- navmenu.component.html -->
<app-blog #blogRef></app-blog>

// navmenu.component.ts
import { Component, ViewChild, AfterViewInit } from '@angular/core';
import { BlogComponent } from '../blog/blog.component';

@Component({
  selector: 'app-navmenu',
  templateUrl: './navmenu.component.html',
  styleUrls: ['./navmenu.component.css']
})
export class NavmenuComponent extends BlogComponent implements AfterViewInit {
  @ViewChild('blogRef') blogRef: BlogComponent;

  ngAfterViewInit() {
    // 在这里可以访问和操作克隆的BlogComponent实例
    console.log(this.blogRef);
  }
}
