How to get an element from Controller?

I need to run 'legacy code' from inside of Controller and need to get element

 function EmailformController($scope) {
     // here I need to get current dom/jqueried element, how to do it? 
 }

You will want to use a directive. You should never be dealing with DOM elements inside of a controller. Only your business logic should go into the controller, DOM manipulation should go in a directive.
