Sendind data between controllers use Service. But what better? Use $on at controller and $broadcast at service; Or simply javascript Object? (Exp: 

myapp.factory('MyService', function(){
    var obj = {};

    return{
        setObject: function(value){
            obj.value = value;
        },

        getObject: function(){
            return obj;
        }
    };
});

  • What is your actual use case? – Wottensprels Aug 21 '14 at 07:16
  • @Sprottenwels I have search controller with can search by 3 instance. That controller has 'Search' button and tabs which choose searched instance. Another - Instance1Controller may generated view for searched list. So I may exchange data between controllers. – Geray Suinov Aug 21 '14 at 07:20
  • @Sprottenwels and global question: at what situation use each method?)) – Geray Suinov Aug 21 '14 at 07:22

you can exchange data between two controllers by using same service example: 

myapp.controller('myController', ['$scope','MyService'
function ( $scope,myService) {
   var obj={};
   obj=myService.setObject();
   $scope.obj=obj;
}]);

myapp.controller('myController2', ['$scope','MyService'
function ( $scope,myService) {
   var obj2={};
   obj2=myService.setObject();
   $scope.obj2=obj2;
}]);

 myapp.factory('MyService', function(){
    var obj = {};

    _setObject = function (value) {
      obj.value = value;
      return obj;
    }

    _getObject = function () {
        return obj;
    }

    return {
        setObject : _setObject ,
        getObject :_getObject 
    }
});

controllers contains the reference of service object when one controller change the object the other controller object automatically get changed because they shared the same reference of that service object

  • I know that, but I asked what method more better – Geray Suinov Aug 21 '14 at 07:41

    this is better because $broadcast and $on starts event bubbling and creats more $watches which slows the perfomance and not easy to manage . and secondly angular also say use minimum $on and broadcast as possible for more http://stackoverflow.com/questions/11252780/whats-the-correct-way-to-communicate-between-controllers-in-angularjs – malik rizwan Aug 21 '14 at 07:53
