angularjs - How do I pass the variable in a function into my controller? -

i'm trying pass videourl variable in showresponse function controller. i've been trying figure out solution without success. can guide me in right direction?

var myapp = angular.module('myapp', []);  myapp.controller('mainctrl', ['$scope', function($scope){     $scope.videourl = videourl; }])  // helper function display javascript value on html page. function showresponse(response) {     var videourl = [];     (prop in response.items) {         videourl[prop] = "https://www.youtube.com/embed/" + response.items[prop].snippet.resourceid.videoid;         } }  // called automatically when javascript client library loaded. function onclientload() {     gapi.client.load('youtube', 'v3', onyoutubeapiload); }  // called automatically when youtube api interface loaded function onyoutubeapiload() {     gapi.client.setapikey('#######');     search(); }  function search() {     // use javascript client library create search.list() api call.     var request = gapi.client.youtube.playlistitems.list({         part: 'snippet',         playlistid: '########'     });      // send request api server,     // , invoke onsearchrepsonse() response.     request.execute(onsearchresponse); }  // called automatically response of youtube api request. function onsearchresponse(response) {     showresponse(response); } 

it better/easier if stuff into angular, it's happening within services. that's how data sharing supposed happen in angular. maybe that's challenging due nature of onclientload. dirty way is:

get controller's scope directly , set on scope. assuming you've got defined like:

<div ng-controller="mainctrl"></div> 

you can controller's scope using jquery:

function showresponse(response) {   var videourl = [];   (prop in response.items) {     videourl[prop] = "https://www.youtube.com/embed/" + response.items[prop].snippet.resourceid.videoid;       }   var scope = $('[ng-controller="mainctrl"]').scope();   scope.videourl = videourl; } 

note cause angular purists weep , gnash teeth.
