success(function(data) {    angular.forEach(data.response.venues, function(item) {                        var pin = {                        latitude: parseFloat(item.location.lat),                            longitude: parseFloat(item.location.lng),                            title: item.name,                            id: item.id                     }                     pin.options = {                                             icon: $dynamicConstants.getCdnImagesUrl() + query + '.png',                                             labelStyle: { 'overflow': 'visible' }                     };                     $scope.map.markers.push(pin);                 })             }).error(function() {             });請問如何function(data)外獲取到var pin的值？
