Angular - Renderer2 :如何设置没有值的属性？

import { Component, Renderer2, ElementRef } from '@angular/core';

@Component({
  selector: 'app-example',
  template: '<div #myDiv></div>'
})
export class ExampleComponent {
  constructor(private renderer: Renderer2, private el: ElementRef) {
    const divElement = this.el.nativeElement.querySelector('#myDiv');
    this.renderer.setProperty(divElement, 'disabled', true);
  }
}
