如何从angular中的typescript文件中获取背景颜色，并将其绑定到我的html页面？

backgroundColor: string;

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

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.css']
})
export class YourComponent implements OnInit {
  backgroundColor: string;

  constructor(private elementRef: ElementRef) { }

  ngOnInit(): void {
    const element = this.elementRef.nativeElement;
    this.backgroundColor = window.getComputedStyle(element, null).getPropertyValue('background-color');
  }
}

<div [ngStyle]="{'background-color': backgroundColor}">
  <!-- 其他内容 -->
</div>
