Angular communication between controllers and directives

Question

I have this piece of code which allows a user to leave comments on a list of items. I created a directive and listen to keydown in order to let the user submit a comment if keyCode == 13.

Not sure if I should include the code to post a comment within the directive. What is the best way to communicate between controllers and directives?

I also check whether or not the input is empty before submitting the comment. It works but not sure this is Angular best practice?

Here is my plunker.

Answer 1

you don't need to write a directive, if you want to use ng-keydown..

example:

template:

<input type="text" ng-model="myText" ng-keydown="checkKeyCode($event)">

controller: -- written in coffeescript

$scope.checkKeyCode = ($event)->
  if $event.keyCode == 13 and $scope.myText?
    $scope.doSomething()
