我有一个角度滤镜设置很好用:

categorieFilter = angular.module("categorieFilter", [])
categorieFilter.controller("catFilter", ["$scope", "store", function($scope, store){
    $scope.search = "";
    $scope.products = [];
    $scope.categories = [];

    $scope.categories = store.getCategories();
    $scope.products = store.getProducts();

    $scope.filterProductsByCats = function(category){
        $scope.search = category;
    };
}])
categorieFilter.factory('store', function(){
            var categories = ['Lattes','CC Blend','Frappes'];
            var products = [
                {name: 'Latte machiatto',category: 'Lattes'},
                {name: 'Frappe ice',category: 'Frappes'},
                {name: 'Latte caramel',category: 'Lattes'},
                {name: 'Frappe speculoos',category: 'Frappes'},
                {name: 'Cappucino',category: 'CC Blend'},
                {name: 'Filter coffee',category: 'CC Blend'},
            ];
            return {
                getCategories : function(){
                    return categories;
                },
                getProducts : function(){
                    return products;
                }
            };
        }); 

但是var类别和var产品仍然是硬编码的,所以我想从我的服务器中检索所需的数据来填充这些变量。而我似乎无法做到这一点?我有另一个功能,我可以获得所需的数据,但我不知道如何获得这些2合1 ......?

categories = angular.module('categories', []);
categories.controller("category",function($scope, $http){
    var serviceBase = 'api/';
    $http.get(serviceBase + 'categories').then(function (results) {
        $scope.categories = results.data;
        for(var i = 0; i < $scope.categories.length; i++){
            var categories = $scope.categories[i];
        }
});
});

那么如何正确地将var类别设置为所需的$ http.get以将我的服务器数据检索到上面的过滤器中呢?

答案 0 :(得分:2)

我认为您应该能够摆脱服务中的硬编码块并返回:

return {
    getCategories: $http.get('/categories').success(function (data) {
        return data;
    }),

    getProducts: $http.get('/products').success(function (data) {
        return data;
    })
}

确保为服务正确设置了依赖关系(即$http):

.factory('store', function ($http) {
    // The above return block here
});

这应该可以解决问题!
