Javascript 如何在AngularJS中获得服务方法的结果？

我有以下代码：

PostApp.factory('loadPage', function ($http) {
return {
    loadOtherPage: function (page, status, permition, order, cultureId) {
        $http({
            url: '/Administrator/Post/PagedIndex',
            method: "POST",
            data: { page: page, status: status, permition: permition, order: order, cultureId: cultureId }
        }).success(function(data) {
            return  data;
        });

    }
};

}))

))

但不要将中loadPage.loadOtherPage服务的响应设置为$scope.ListOfItems变量。 浏览器控制台中的响应为json：

[{"PId":15,"Id":15,"Status":"انتشار","Permition":"سراسری","PublishedDateEn":"08/19/2013","Title":"xxxxxxxxxxxx","CultureId":1,"Username":"naser","CommentCount":0},{"PId":16,"Id":16,"Status":"انتشار","Permition":"سراسری","PublishedDateEn":"08/19/2013","Title":"yyyyyyyyyyyyyyyyyy","CultureId":1,"Username":"naser","CommentCount":0},{"PId":17,"Id":17,"Status":"انتشار","Permition":"سراسری","PublishedDateEn":"08/21/2013","Title":"zzzzzzzzzzzzzzzz","CultureId":1,"Username":"naser","CommentCount":0}]

最终$scope.ListOfItems为空？

（编辑：添加变量以提高清晰度）

loadOtherPage

函数不返回任何内容，这就是为什么

$scope.ListOfItems

为空。正确的方法是：

loadOtherPage: function (page, status, permition, order, cultureId) {
    var httpPromise =  $http({
        url: '/Administrator/Post/PagedIndex',
        method: "POST",
        data: { ... }
    });
    return httpPromise;
}

实际上，您将

$http

返回的承诺返回给调用者。您的控制器应为：

$scope.loaddata = function () {
    var loadPagePromise = loadPage.loadOtherPage( ... );
    loadPagePromise.success(function(data) {
        $scope.ListOfItems = data;
    });
};

---

非常好。但我在服务中的loadOtherPage函数中返回数据：$http（{url:'/Administrator/Post/PagedIndex'，方法：“Post”，数据：{…}）；tanks.

.success（函数（数据）{return data；}）

在请求成功时只注册一个额外的回调<代码>返回数据不是

loadOtherPage

的

return

语句。这是您要赋予

success（）

的匿名函数的

return

语句。函数式语言是个婊子，我知道…：P

$scope.loaddata = function () {
    var loadPagePromise = loadPage.loadOtherPage( ... );
    loadPagePromise.success(function(data) {
        $scope.ListOfItems = data;
    });
};
