我正在解决在两个 Controller 中通过范围访问重用相同函数的问题 在这里描述: How to include/inject functions which use $scope into a controller in angularjs?
在 Controller 中:
new CommonService($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?
最佳答案
您还没有将 $scope 放入“成功”闭包中,请尝试使用此代码:
services.factory("CommonService", function (DBService) {
function Factory ($scope) {
this.$scope = $scope;
}
Factory.prototype.getSomethingFromDB = function () {
if( angular.isUndefined(this.$scope.vrsteObracuna) || this.$scope.vrsteObracuna === null) {
this.$scope.loading = true;
var that = this;
DBService.getSomethingFromDB(
function success(data) {
that.$scope.loading = false; //ERROR !!!
that.$scope.vrsteObracuna = data;
},
function error(data, status, headers, config) {
that.$scope.loading = false;
etna.notifications.error("Error fetching!");
}
)
}
return this.$scope.vrsteObracuna;
}
return Factory;
});
关于javascript - 使用 $scope 访问 Angular 重用函数,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/40906183/
