javascript - 将数据从工厂传输到 Controller

Question

不知何故，我无法将数据从工厂方法获取到 Controller 。我正在使用 javascript 远程处理，下面给出了工厂

function userRecordFetchFactory($rootScope) {
        var custRec = {};   
            return {                                        
                checkRecordType : function(urlObject) {
                 function loadRecordType(err, records, event) {
                        if (err) {
                            displayReadingInformationErrorView();
                        } else if (records != null && records.length == 0) {
                            displayReadingInformationErrorView();
                        } else {
                             custRec = {
                                Name : records[0].get('Name'),
                                lat : records[0].get('Latitude__c'),
                                lon : records[0].get('Longitude__c'),
                                SiteStreet : records[0]
                                        .get('SiteStreet__c'),
                                SiteCity : records[0].get('SiteCity__c'),
                                SiteCountryCode : records[0]
                                        .get('SiteCountryCode__c'),
                                SitePostalCode : records[0]
                                        .get('SitePostalCode__c'),
                                AddressID : records[0].get('AddressID__c'),
                                loaded : true
                            };

                        }
                    }
                    if (urlObject && urlObject.aid
                            && urlObject.aid.startsWith(accPrefix)) {
                        objModel = new RemoteObjectModel.Account();
                    }
                    if (urlObject && urlObject.aid
                            && urlObject.aid.startsWith(leadPrefix)) {
                        objModel = new RemoteObjectModel.Lead();
                    }

                    if (objModel) {
                        objModel.retrieve({
                            where : {
                                Id : {
                                    eq : urlObject.aid
                                }
                            }
                        }, loadRecordType);
                    }

                    return custRec;
                }
            };
        }

下面给出了我的 Controller 来访问数据

function LocatorInitController($document, $scope,
                userRecordFetchFactory) {
                console.log("inside the controller"+urlParams);
                $scope.CustomerSite = {};
                userRecordFetchFactory.checkRecordType(urlParams)
                .then(function successData(data){
                $scope.CustomerSite = data.data;
                execGeoCoding();
                });

我收到错误无法读取未定义的属性成功。在工厂中，方法 checkRecordType 有一个检索函数，它是一个 javascript 远程调用，并且该函数有一个对 loadrecordtype 的回调。

建议你用更简单的方式来编写你的工厂以便于阅读。你所有的嵌套导致你无法轻易看到整个事情

将所有可访问的成员放在顶部

// pass functions as references to object properties
// can easily see the whole factory object at top of the file
var custRec = {
  checkRecordType : checkRecordType,
  subscribe       : subscribe    
};

return custRec;


// move function declarations to the bottom and out of the way

function checkRecordType(){
    /// do stuff
    return stuff;
}

function loadRecordType(err, records, event) {
   /// do stuff
    return stuff;
}

function subscribe(scope, callback){
   /// do stuff
    return stuff;
}
