【问题描述】:
我正在解决在两个控制器中重用具有范围访问权限的相同功能的问题 在这里描述: How to include/inject functions which use $scope into a controller in angularjs?
在控制器中:
new CommonService($scope).getSomethingFromDB();
在工厂:
services.factory("CommonService", function (DBService) {
function Factory ($scope) {
this.$scope = $scope;
}
Factory.prototype.getSomethingFromDB = function () {
if( angular.isUndefined(this.$scope.vrsteObracuna) || this.$scope.vrsteObracuna === null) {
this.$scope.loading = true;
DBService.getSomethingFromDB(
function success(data) {
this.$scope.loading = false; //ERROR !!!
this.$scope.vrsteObracuna = data;
},
function error(data, status, headers, config) {
this.$scope.loading = false;
etna.notifications.error("Error fetching!");
}
)
}
return this.$scope.vrsteObracuna;
}
return Factory;
});
问题是从 DBService.getSomethingFromDB 成功回调后 this.$scope.loading 未定义?
