How can we direct the user to another tab in Angular Mat Tab using a child component?

Within my Angular page, I have implemented 4 tabs using mat-tab. Each tab contains a child component that encapsulates smaller components to cater to the specific functionality of that tab.

Now, I am faced with the challenge of navigating the user from a child component within one tab to either the 2nd or 3rd tab with the click of a button. How can I achieve this navigation between tabs when the child component is nested deep within another tab?

It's worth noting that I am not utilizing the router in this scenario, and I also need to figure out how to pass a data object to a child component located in a different tab.

Answer №1

When tackling this issue, consider the following approaches:

  1. Continuously emit @Output events from your child component until they reach the parent component, where you can manage the tabs.

  2. Pass a Subject to the child components from the parent component for subscription in the parent component. Use .next(index:number) to send messages back to the parent component.

  3. If your child components are deeply nested and scattered, create a global service with a Subject. Implement a method like changeTab(index:number) within which you call subject.next(index). In the parent component, subscribe to the global service to handle tab changes accordingly.
