Vue 3 - how to read data from a slave?

Question

Vue.js

Good afternoon. There is a desire but no idea how to read data from child components.

For example, there is such a thing

<parent>
       <child></child>
       <child></child>
</parent>

There is a computed variable in child , I need to read it from parent. I don’t want to hang anything on child, not any ref. I want it straight.

Are there any ideas

Answer 1

1) Throw a callback
2) Use $emit from child
3) store data globally (use vuex)

Answer 2

Do you want vuex? Make a separate state object with reactive api and use it in both parent and child

Answer 3

Thanks everyone, I figured it out myself.

<parent >
       <child ref="row-1"></child>
       <child ref="row-2"></child>
</parent>
