How to pass variable from child to parent component?

Question

Vue.js

I have a regular show variable that shows and hides an element (show=false).
There is a mousedown event in the parent component, I want the show to change its value during this event. How can I pass this variable without vuex? I don’t quite understand how via emit because in those situations the events were called in the child component. I want to note that I am making a vue plugin and I have no idea how to make an event bus there

Answer 1

Try in child component to use $parent.show
