How to clear element from all children in Angular (5+) Renderer2?
Angular Renderer2 is recommended to manipulate DOM programatically.
In my directive i take some el.nativeElement.innerText, transform this text and want to add it to my element:
el.nativeElement.innerText
const text = renderer.createText(`$el.innerText%`);
renderer.appendChild(el, text);
const text = renderer.createText(`$el.innerText%`);
renderer.appendChild(el, text);
The problem is with el - it already has the text, so it appends transformed text after it.
el
I checked Renderer2 docs and it seems I can use removeChild() without passing reference to child, so I can't use Renderer2 to clear component first?
removeChild()
In this case only way to achieve it is using innerText = '' before renderer methods, which makes it pointless.
innerText = ''

Maybe something like:
const childElements = this.el.nativeElement.children;
for (let child of childElements)
this.renderer.removeChild(this.el.nativeElement, child);
