How to cancel render in vue&?

Question

Vue.js

I make a kind of tabs, from a child element, I call the parent method, which **does not matter much** while I need the child itself to not form html. Can't figure out how to do it better?

mounted: function () {
      let tab = {
        title: this.title,
        content: this.$el.innerHTML
      };
      this.$parent.addTab(tab);
    },

that is, you need to cancel the render.
And if anyone knows how to get data from
<slot></slot>more elegant (more correct) than this.$el.innerHTML- in general, I will say thanks

Answer 1

why not insert the component into the parent instead of this perverted html copy?

Answer 2

It's not very clear what you want to do. Do you want to extract html from a child component, and so that the component does not draw this html? It seems to me that this is not possible. And I don't think that's right.
Maybe then you don't need to use this child component, but just draw this html in the parent?
