You can use ElementRef. E.g.

您可以使用ElementRef. 例如

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

@Component({
  selector: 'test-text',
  template: `<p> Text </p>`
})
export class TestComponent {
  elRef: ElementRef

  constructor(elRef: ElementRef) {
    this.elRef = elRef;
  }      

  getHtmlContent() {
    //This will return '<p> Text </p>' as a string
    return this.elRef.nativeElement.innerHTML;
  }
}
