Angular ngController vs Controller constructed within Directive

Question

I\'m wondering what the use cases are for these two methods of creating a controller:

Using ngController:

myApp.controller(\'myContr         


        

Answer 1

Adding some detail regarding accessing methods and values within the directive controller:

Parent directive

myApp.directive ( 'parent', [ function() {
    return {
        restrict: 'A',
        scope: {},
        controller: [ '$scope', function( $scope ) {
            //this.myVar = ''; //accessible in child directives
            //$scope.myVar = ''; //accessible in template
            $scope.myVar = this.myVar = '';
        }],
        template: '
 {{myVar}} 
',
        link: function( scope, element, attrs ) {

            console.log( scope.myVar );

        }
    };
}]);

Child directive

myApp.directive ( 'child', [ function() {
    return {
        restrict: 'A',
        require: '^parent',
        link: function( scope, element, attrs, ctrl ) {

            console.log( ctrl.myVar );

        }
    };
}]);
