I am working on a page in a Laravel 5.7 application, that has a series of VueJS child components "Prospect" wrapped within a VueJS parent component "Prospects". The child components are table rows that each have a button to delete the row/child. The parent component has a button that deletes multiple child components.
However I am unsure as to how to get the parent component function to call the child component functions to delete the children that have been marked for deletion.
Deleting the child components one at a time from within the child component itself works fine. However I am trying to call the same Child component delete function multiple times from the loop within the parent component function deleteSelectedProspects().
From within deleteSelectedProspects() i need to access the index assigned to the child component, in order to reference the correct row in the $refs array.
How can I access the index of the child component in order to properly reference it in the $refs array inside the selectedBoxes.forEach loop?
