First pass for a keypress directive for Angular.js

jcKeypress.js

  .directive('jcKeypress', function () {
    return {
      template: '',
      restrict: 'AE',
      scope: {
        keyCode: '@',
        keyAction: '&'
      },
      link: function(scope, element, attrs) {
        attrs.altKey = attrs.altKey || false;
        scope.altKey = scope.$eval(attrs.altKey);

        var keyListener = function(event) {
          console.log('KeyboardEvent: ' + event.keyCode + ' altKey: ' + event.altKey);
          if ( event.altKey === scope.altKey ) {
            if ( event.keyCode === parseInt(scope.keyCode) ) {
              if ( scope.keyAction ) {
                scope.$apply(function() {
                  scope.keyAction();
                });
              }
              event.preventDefault();
            }
          }
        };

        // window.addEventListener('keydown', keyListener);
        window.addEventListener('keypress', keyListener);
      }
    };
  });
