角1.2 $ Q休息

Question

$scope.model.initJobs = function(forceLoad){ 
    var deferred = $q.defer(); 
    var companyId = authService.getCompanyId(); 
    if(!Boolean(companyId) || companyId == 'undefined'){//no data was loaded yet - bummer 
     deferred.resolve([]); 
     return deferred.promise; 
    } 
    var jobs = jobsService.getJobs(companyId); 
    if(jobs && !forceLoad){ 
     deferred.resolve(jobs); 
     return deferred.promise; 
    } 

    $scope.__loading = true; 
    jobsService.getCompanyJobs(companyId).then(function(data){ 
     $scope.__loading = false; 
     jobsService.setJobs(data.data, companyId); 
     deferred.resolve(data.data); 
    }, 
    function(errorData){ 
     $scope.__loading = false; 
     $location.path('/notfound'); 
     jobsService.setJobs([], companyId)//those line are a precuation 
     deferred.resolve(data.data); 
    }); 
    return deferred.promise; 
} 

$scope.model.initJobs(true).then(function(data){ 
     $scope.model.jobs = data; 
    }); 

下凍結與角1.2.0和1.2.1的屏幕，是不是因爲我返回defrred。在相同的功能內多次承諾？ 這裏的想法是不加載數據，如果我已經存儲在我的服務。

有什麼想法？ 任何幫助表示讚賞&歡迎。

編輯： 我也許應該提一下，上面的ht在AngularJS 1.0.8上工作得很好！

你正在讓它變得比它需要的更難，通常你永遠不需要延期。

$scope.model.initJobs = function (forceLoad) { 
    var companyId = authService.getCompanyId(); 
    if (!Boolean(companyId) || companyId == 'undefined') { //no data was loaded yet - bummer 
     return $q.resolve([]); 
    } 
    var jobs = jobsService.getJobs(companyId); 
    if (jobs && !forceLoad) { 
     return $q.resolve(jobs); 
    } 

    $scope.__loading = true; 
    return jobsService.getCompanyJobs(companyId) 
    .then(function (data) { 
     jobsService.setJobs(data.data, companyId); 
     return data.data; 
    }) 
    .catch(function (errorData) { 
     $location.path('/notfound'); 
     jobsService.setJobs([], companyId) //those line are a precuation 
     //You seem not have tested because this won't work 
     return data.data; 
    }) 
    .finally(function() { 
     $scope.__loading = false; 
    }); 
}
