js code in controller

[eluser]spherop[/eluser]
is there anything i should be wary of in including blocks at the bottom of my controllers for js controller logic?

I assume you are echoing javascript in the controllers?

I tend to write my js in views, however sometimes I cheat and just echo json return data in the controller.

The only thing you should be wary of is maintainability. if you have a large applications with every controller containing blocks of javascript it may become unreadable.
