I am trying to attach a keyup event to a directive in my Angular project. Here is the directive:

angular.module('clinicalApp').directive('chatContainer', function() {
  return {
    scope: {
      encounter: '=',
      count: '='
    }
    templateUrl: 'views/chat.container.html',

    link: function(scope, elem, attrs) {
      scope.count = 500;
    }
  };
});

And here is the html from the template:

<div class="span4 chat-container">
  <div class="chat-body">
    <form accept-charset="UTF-8" action="#" method="POST">
      <div class="text-area-container">
        <textarea id="chatBox" class="chat-box" rows="2"></textarea>
      </div>
      <div class="button-container btn-group btn-group-chat">
        <input  id="comment" class="btn btn-primary btn-small btn-comment disabled"  value="Comment" ng-click="addMessage()"/>
      </div>
    </form>
    </div>
  </div>
</div>

I want to access the chatbox in my link function and attach the keyup event to it. I know I can get it with jQuery, but that cannot be the Angular way. What is the proper way to grab that element from the dom?

You can easily do it with Angular' element' find() method:

 var chatbox = elem.find("textarea");  // Finding
 chatbox.bind("keyup",function(){      // Binding
     console.log("KEYUP!")
 })
