onMount hook of toDOM

1

I want to access the element rendered by “toDOM”, is there any hook can do that?

2

No, but you can just create actual DOM elements in toDOM and return those.

3

You mean I can write like this?

toDOM() {
  const someElement = document.createElement('div');
  someElement.textContent = 'hello world';

  return someElement;
}

If I can do like this, how can I express the 0 of ['div', 0] ??

4

Use the {dom, contentDOM} return format.

But if I want to make the content I input automatically become div’s content ( Just like 0 means ), what should I put into contentDOM ?

6

The parent of where your 0 was (which may be the same element as dom).

Hey, I got another question :joy: When I need bind an event listener to that element, how can I safely remove it to avoid memory leaks ?

It hasn’t been necessary to remove event listeners to prevent memory leaks for about 10 years (unless you are somehow holding on to a reference to the DOM element the listener is registered on).
