i don't know what you are trying to do but this is one of the methods to get the action.
print_r(explode('@',Route::currentRouteAction()));
Output
Array ( [0] => HomeController [1] => index )
so 1st element will hold the controller (provided not namespaced, otherwise you will have to remove the namespace part manuelly) and 2nd element will hold the action.
your question and the explanation doesn't match.
if you want the action, this is one of the process.
but i think, Andreyco's answer gives you what you need. i just put it for future reference if someone finds it helpful.
@section()tags in your blade views to add your scripts. What does your routes.php file look like (and the controller code that creates the views for these pages)?
