angularjs - Accessing Value from JavaScript Callback -

i'm trying push value anglular.js service callback array. appreciated. thanks.

$scope.checkaddondependencies = function(addon) {     var addons = new array();     var arr = filterfilter($scope.addons, {checked: true});     var length = arr.length, element = null;      (var = 0; < length; i++) {         element = arr[i]['addoncode'];         addons.push(element); //works fine          myservice.addon_dependencies(arr[i]['addoncode']).then(function(dependency) {              addons.push(dependency); //not working         });      }      console.log(addons);     } 

basically need handle value in callback this:

myservice.addon_dependencies(arr[i]['addoncode']).then(function(dependency) {     addons.push(dependency);  }); 

update

since callback of function then() async, there no guarantee console.log(addons) shows in code order.
