问题
I've been creating a Google Maps API MVC5 application for the past weeks.
I know that I should keep all the logic inside the controller, but I have the following doubt: In my main View I have a button called "Avoid tolls". By pressing that button the user will see the route distances calculated previously in the controller (both with and without tolls).
My question is: Why should I get the route's distances in the controller (xml service) with and without tolls when I could do that inside the View ONLY if the user wanted to check the route distance without tolls? I feel I'm loosing time accessing information (xml service) that most likely will not be demanded by the user.
Perhaps there's a way to make the view go back to the controller by the time the button is pressed. Is that it?
Thank you!

you can hook the button upto an ajax request in javascript and request the additional info from the server then update your view based on the result.
