Angularjs 在决心中注入决心

我想知道，是否可以将一个resolve参数注入另一个resolve参数。代码将告诉您更多信息：

.state('videos.videosLection', {
        url : '/:lection',
        templateUrl : '/partials/videosLection.html',
        controller : 'VideosLectionCtrl',
        menuItem : 'Videos',
        resolve : {
                selectedLection : function ($stateParams, lections) {
                        ...
                },
                sections : function(Section, selectedLection) {
                        ...
                }                   
         }
})

我使用angular UI路由器进行路由。我需要在开始解析节之前进行SelectedSelection。

有什么想法吗？非常感谢

您能将

SelectedSelection

片段转化为服务吗？然后就这样做：

resolve: {
    sections: function(Section, selectedLectionService, $stateParams, lections){
        var result = selectedLectionService($stateParams, lections);
        // do something with result here...
    }
}

我不知道这是否能满足你的所有需求，但也许它能帮你找到正确的方向。如果没有效果，请告诉我。

我终于明白了，这里的方法是只解析一个对象，它有两个属性，它们本身就是承诺。查看代码：

resolve : {
    data : function($stateParams, lections, Video, Section, $q) {
        // defer for the data object
        var defer = $q.defer();

        // selectedLection
        var selectedLection = null;

        // if there is lection selected
        if($stateParams.lection)
        {
            // lection is selected
            lections.forEach( function(lection)
            {
                // find the selected lection
                if(lection.addressUrl == $stateParams.lection)
                {
                    // save it
                    selectedLection = lection;
                }
            });
        }
        else
        {
            // resolve it with everything empty
            defer.resolve({
                selectedLection : null,
                lectionVideos : [],
                sections: []
            });
            return defer.promise;
        }

        // promise to the lection videos
        var deflectionvideos = $q.defer();
        // find all the videos by the lection id
        Video.GetAllByLection(selectedLection.id, null, function(data) {
            // resolve it with the data
            deflectionvideos.resolve(data);
        }, function(error) {
            // resolve it with empty array
            deflectionvideos.resolve([]);
        });

        // promise for the sections
        var defsections = $q.defer();
        // find all the sections of selected lectino
        Section.GetAllByLection(selectedLection.id, function(data) {
            // resolve it with the data
            defsections.resolve(data);
        }, function(error) {
            // resolve it with empty array
            defsections.resolve([]);
        });

        // wait, untill all the promises for sections and lectionsvideos are resolved
        $q.all([
                deflectionvideos.promise,
                defsections.promise
            ]).then(function(data) {
                // resolve it with actual data
                defer.resolve({
                    selectedLection : selectedLection,
                    lectionVideos : data[0],
                    sections: data[1]
                });
            });

        // return promise for the data object
        return defer.promise;
    }
}

如果你们有其他方法或更好的解决方案，请告诉我：-）

希望它能帮助别人

不。解析继承仅适用于从父状态到子状态。问题是，由于某种原因，我无法访问服务中的$stateParams，因此此解决方案对我不起作用。。或者我做错了什么：-）
