{{providerOutput}} <script> var app = angular.module( 'app', [] ); var MyFunc = function() { this.name = "default name"; this.$get = function() {
this.name = "new name"
return "Hello from MyFunc.$get(). this.name = " + this.name;
}; return "Hello from MyFunc(). this.name = " + this.name;
}; // returns the actual function
app.service( 'myService', MyFunc ); // returns the function's return value
app.factory( 'myFactory', MyFunc ); // returns the output of the function's $get function
app.provider( 'myProv', MyFunc ); function MyCtrl( $scope, myService, myFactory, myProv ) { $scope.serviceOutput = "myService = " + myService;
$scope.factoryOutput = "myFactory = " + myFactory;

</html>
生成结果：
myService = [object Object] myFactory = Hello from MyFunc(). this.name = default name myProvider = Hello from MyFunc.$get(). this.name = new name
app.factory扩展：
factory('AttendersService', function ($q, $http, $rootScope) {
var service = {};
var baseUrl = 'https://itunes.apple.com/search?term=';
var _artist = '';
var _finalUrl = '';
var makeUrl = function(){
_artist = _artist.split(' ').join('+');
_finalUrl = baseUrl + _artist + '&callback=JSON_CALLBACK'
return _finalUrl;
}
service.setArtist = function(artist){
_artist = artist;
}
service.getArtist = function(){
return _artist;
}
service.callItunes = function(){
makeUrl();
var deferred = $q.defer();
$http({
method: 'JSONP',

deferred.resolve(data);

.then(function(data){
$scope.data.artistData = data;
