Question

我有一个搜索控制器和一个类别控制器和一个共享属性工厂。在我的类别控制器中，我设置了一个sharedproperties.property，但我无法在搜索控制器中检索数据，它似乎是空数据，这里是我的代码

.factory('sharedProperties', function () {
        var property = '';

        return {
            getProperty: function () {
                return property;
            },
            setProperty: function(value) {
                property = value;
            }
        };
 })


.controller("SearchCtrl",['config','sharedproperties',function(config,sharedproperties)
{

$scope.search_subCategory_businesses= function()
        {
            $scope.bus_es = sharedProperties.getProperty();
            console.log("sharedProperty hahahaah is",sharedProperties.getProperty()); //logs empty instead of data

            angular.forEach($scope.bus_es,function(value,key)
                        {
                            $scope.business = value;

                            if($scope.business.logo == '' || $scope.business.logo==null)
                            {
                                $scope.business.logo=config.BaseImageURL+"uploads/defbanner.png"
                            }else
                            {
                                $scope.business.logo=config.BaseImageURL+$scope.business.logo;
                            }
                            this.push($scope.business);

                        },$scope.businesses);

        };

        //$scope.search_resultsFunction();
        $scope.search_subCategory_businesses();


}])



.controller("CategoryCtrl",['config','sharedproperties',function(config,sharedproperties)
{

$scope.getBusinesses=function(sub_category_id)
    {
           $.get($scope.BaseURL+"classes/util.php?sub_category_id="+sub_category_id+"&transaction=get_businesses",function(results){

                alert("results are"+JSON.parse(results));
                $scope.bus_es =JSON.parse(results);
                sharedProperties.setProperty($scope.bus_es);//successfully sets property

                console.log("sharedProperty is",sharedProperties.getProperty());
                window.location.href=BaseURL+"search.php";
        });


    }

}])

您正在混合使用jQuery回调和Angular Promises。你应该通过$ http调用BackEnd并使用promises。 $ http：https://docs.angularjs.org/api/ng/service/ $ http

.factory('sharedProperties', function () {
        var property = '';

        return {
            getProperty: function () {
                return property;
            },
            setProperty: function(value) {
                property = value;
            }
        };
 })


.controller("SearchCtrl",['config','sharedproperties',function(config,sharedproperties)
{

$scope.search_subCategory_businesses= function()
        {
            $scope.bus_es = sharedProperties.getProperty();
            console.log("sharedProperty hahahaah is",sharedProperties.getProperty()); //logs empty instead of data

            angular.forEach($scope.bus_es,function(value,key)
                        {
                            $scope.business = value;

                            if($scope.business.logo == '' || $scope.business.logo==null)
                            {
                                $scope.business.logo=config.BaseImageURL+"uploads/defbanner.png"
                            }else
                            {
                                $scope.business.logo=config.BaseImageURL+$scope.business.logo;
                            }
                            this.push($scope.business);

                        },$scope.businesses);

        };

        //$scope.search_resultsFunction();
        $scope.search_subCategory_businesses();


}])



.controller("CategoryCtrl",['$http','config','sharedproperties',function($http,config,sharedproperties)
{

$scope.getBusinesses=function(sub_category_id)
    {
           $http.get($scope.BaseURL+"classes/util.php?sub_category_id="+sub_category_id+"&transaction=get_businesses").then(function(results){

                alert("results are"+JSON.parse(results));
                $scope.bus_es =JSON.parse(results);
                sharedProperties.setProperty($scope.bus_es);//successfully sets property

                console.log("sharedProperty is",sharedProperties.getProperty());
                window.location.href=BaseURL+"search.php";
        });


    }

}])

更好的做法是在负责与后端通信的服务中进行这些http调用。
