What is the best way to switch to a different view when user navigates to a different url. In angular there is ng-view that takes care of this and inserts corresponding templates and in ember its all route based.
Is it better to just hide other views elements on routing using css or destroying other views and inserting current view?
EDIT
It would be great if someone could give an example how to re-render the view on navigating back to it again and restoring its previous state.
Eg.
if you have a check-box in a view that user can select to add some item to the cart , but in the middle he/she moves to some other url and then comes back, that check-box should be checked.
I would have a main content view with subviews and call remove on it, which is responsible for cleaning up any subviews too (calling remove on them first and going up the hierarchy tree). The concept of subviews doesn't come for free with backbone but isn't hard to implement. And finally attach a new content view.
This ensures you can cleanup and the browser is using a consistent amount of resources.
I would abstract this into some kind of layout view which has a content subview and a function like setContent(view) which handles the remove of any existing content view and the attach of the new one.
Personally I would have a router with sub routers in modules, e.g. a main router which finds a route starting with "checkout" and passes it over to a sub router in the checkout module which is responsible for attaching a new content view.
In Backbone the implementation is up to you which is both good and bad, depending on how nice you do it ;)
