app = angular.module("gallery", []);

app.controller("galleryController", ['$scope','$http', function($scope, $http){
    var gallery = this;
    gallery.data = [];

    gallery.getJson = function(){
        $http.get('/urltojson/main-hero.json').success(function(data){

        });
    }

    this.getJson();
}]);  })();

is it possible to call getJson from outside the controller?

Answer 1

Use angular.element and get the scope() of the element that resides within the controller you want to call methods on.

Example:

<div ng-controller="galleryController"><span id="test"></span></div>

You can do:

var scope = angular.element( document.querySelector( '#test' ) ).scope();
scope.getJson();
