so far tried code below...

factory.js

        angular.module("app").factory('geotreefactory', function() {             return {   gettreecheck: function (geolocation) {       if (geolocation.id === 5657){         $.each(geolocation.parent(),function(index,location) {           if (location.id !== geolocation.id) {             $.each(location._childrenoptions.data.items,function(index,child){               var disablechildid = 'disabled' + child.id;               var model = $parse(disablechildid);                 model.assign($scope, true);             })             var disableitemid = 'disabled' + location.id;             var model = $parse(disableitemid);             model.assign($scope, true);           }         });       }       // if child checked disable parents       try {           var parent = geolocation.parent().parent();           var disableparentid = 'disabled' + parent.id;           var parentmodel = $parse(disableparentid);           parentmodel.assign($scope, true);       } catch (err) {      // ignore since happens when node selected has no children          }      //expand , collapse tree on parent check childrens can disabled.       $scope.riskinprcsgeolocationtree.expand($scope.riskinprcsgeolocationtree.findbytext(geolocation.text));       $scope.riskinprcsgeolocationtree.collapse($scope.riskinprcsgeolocationtree.findbytext(geolocation.text));       //if parent item checked, disable children       if(geolocation.items) {           $.each(geolocation.items,function(index,location) {             var disableitemid = 'disabled' + location.id;             var model = $parse(disableitemid);             model.assign($scope, true);           });       }        },        //else block function if ocnditions false       gettreeuncheck: function(geolocation) {         if (geolocation.id === 5657){           var getparent = geolocation.parent();           $.each(geolocation.parent(),function(index,location) {             if (location.id !== geolocation.id) {               $.each(location._childrenoptions.data.items,function(index,child){                 var disablechildid = 'disabled' + child.id;                 var model = $parse(disablechildid);                   model.assign($scope, false);               })               var disableitemid = 'disabled' + location.id;               var model = $parse(disableitemid);               model.assign($scope, false);             }           });         }         // if child unchecked enable parent         try {           var parent = geolocation.parent().parent();           var checkedchildrens = [];           (var i=0; i<selectedriskgeolocations.length; i++){             var checknodes = selectedriskgeolocations[i];             checkedchildrens.push(checknodes);           }           if (checkedchildrens.length === 0){             var disableparentid = 'disabled' + parent.id;             var parentmodel = $parse(disableparentid);             parentmodel.assign($scope, false);           };       }         catch (err) {           // ignore since happens when node selected has no children          }         //if parent item unchecked,  enable childrens         if(geolocation.items){             $.each(geolocation.items,function(index,location){               var disableitemid = 'disabled' + location.id;               var model = $parse(disableitemid);               model.assign($scope, false);             });         }       } }; 

controller.js

var selectedctlgeolocations = [];                     var selectedctlgeolocationids = [];                     $scope.populatecontrolinprcsgeoloction = function(geolocation) {                         var pos = $.inarray(geolocation.text,selectedctlgeolocations);                         if (pos < 0) {                             selectedctlgeolocations.push(geolocation.text);                             selectedctlgeolocationids.push(geolocation.id);                              // if parent item checked, disable                             // children                          geotreefactory.gettreeifblock();                          } else {                             selectedctlgeolocations.splice(pos, 1);                             selectedctlgeolocationids.splice($.inarray(                                     geolocation.id, selectedctlgeolocationids),                                     1);                              // if parent item unchecked, enable                             // children                             geotreefactory.gettreeelseblock();                         }                      }; 

alright, way off here, you're trying do?

app.factory('myservice', function(){   return {     ifblock: function(){       // code run if condition true     },     elseblock: function(){       // code run if condition false     }   } });  app.controller('main', function(myservice){   $scope.myevent = function(geolocation){     if(condition){       myservice.ifblock(geolocation);     } else {       myservice.elseblock(geolocation);     }   } }); 

you solve problem (and if understand problem correctly, preferred method):

app.service('myservice', function(){   return {     go: function(geolocation){       if(condition){         // code run if condition true       } else {         // code run if condition false       }     }   } });  app.controller('main', function(myservice){   $scope.myevent = function(geolocation){     myservice.go(goelocation);   } });
