innerHTML is not working for some tags like button or custom tags [duplicate]

Answer 1

innerHTML is not a attribute exposed as a property of HTML Element.

So this will not work.

You can use @ViewChild to access DOM Element

app.component.html

app.component.ts

import {ElementRef} from '@angular/core';
@ViewChild('someVar') el:ElementRef;

constructor() {}

ngAfterViewInit() {
      this.el.nativeElement.innerHTML = "some html";
}
