Question

There are four routing components A, B, C, and D under the parent component APP. There are A1, B1, C1, and D1 subcomponents under these four routing components respectively. There is also an E component under the app. When these components A1, B1, C1, and D1 are clicked, the methods in the E component are triggered and the corresponding parameters are passed to the methods in the E component.

You can set the value of E component computed store, and then watch this value, and then trigger watch's handler according to the value of store. If you need to trigger it every time you click on the same component, you need to trigger it every time Every click changes a value, and computed should be cached.
A better way would be to write an action as vuex, and then import this action in each component, and you can use it.
