如何知道是否有溢出隐藏的子div:隐藏在Angular6中

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

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.css']
})
export class YourComponent {
  @ViewChild('childDiv', { static: true }) childDiv: ElementRef;
}

ngAfterViewInit() {
  const isOverflowHidden = this.childDiv.nativeElement.scrollHeight > this.childDiv.nativeElement.clientHeight ||
    this.childDiv.nativeElement.scrollWidth > this.childDiv.nativeElement.clientWidth;
  
  if (isOverflowHidden) {
    console.log('子div存在溢出隐藏的内容');
  } else {
    console.log('子div没有溢出隐藏的内容');
  }
}
