我正在使用AngularJS和PersistenceJS开发应用程序。

我在处理异步调用时遇到了麻烦

控制器:

cars.controller('CrashWidgetOneCtrl',function($scope, $location, $routeParams, CrashServices){
    if($routeParams.crashId){
        $scope.data = {};
        console.log("CrashID: "+$routeParams.crashId);
        crashId = $routeParams.crashId;
        alert(1);//Works

        CrashServices.getCrashDetails($scope, crashId).then(function(result){
            console.log(result);
            alert(2);//Never Fires
        });
    alert(3);//Gets executed
    }else{
        console.log("N");
    }

});


服务 :

cars.factory('CrashServices', function($http, $location, $q, CommonServices,$rootScope, $timeout){
    return{
        getCrashDetails:function($scope, crashId){
        var deferred = $q.defer();
        // Get user details if any
        $scope.$apply(function(){
            var crashInfoTable = App.CrashInfoTable.all();
            alert(4);
            crashInfoTable.list(null, function (results) {
                alert(5);//This also doesn't work
                deferred.resolve();
            });
        });
        return deferred.promise;
        }
    }

});


任何帮助将不胜感激。非常感谢。

注意:我正在使用PersistenceJS。

最佳答案

我不知道您是否需要scope.apply。
这似乎对我有用:

getCrashDetails:function($scope, crashId){
    var deferred = $q.defer();
    // Get user details if any
    App.CrashInfoTable.all().list(null, function(results) {
        deferred.resolve(results);
    });
    return deferred.promise;
}
