Answer №1

If the components' structure remains constant, one can attempt accessing them using this.$parent.$parent. However, navigating to the Page is feasible with this method, but dealing with PageForm inside the slot area becomes problematic.

Although theoretically possible to attach a ref to a component and access a method through it, the behavior in such cases tends to be unpredictable...

The most reliable approach is to exchange data through props/emit if the components are adjacent to each other.
