代码工作正常，直到我决定将我的登录和注册表单移动到它自己的部分，现在在我登录后，它确实重定向到 partials/dashboard.html 但我的用户对象数据不再可访问。我在我的 script.js 中有 console.logged 进行检查，该对象确实得到了控制台，但我无法在我的 dashboard.html 上访问它

索引.html

            });
        }
     })

服务器端代码工作正常，因为用户注册工作正常，登录表单确实抓取了用户对象。到目前为止，添加主题也运行良好。

这是我的 Chrome 控制台正在打印的内容

我确定它会是非常小但看不见的东西。提前感谢您的帮助..谢谢

已经更新了代码，隔离了 Controller 以避免混淆，但仍然没有，如果你看到我添加了一个

console.log($scope.$storage.user.name);

在我的 loginController 中的本地存储中设置数据之后。它实际上在我的 Chrome Javascript 控制台中执行 console.log 名称字段。但不是在 dashboard.html 中打印

最佳答案

通过在 $rootScope 而不是 $scope 中设置数据来修复它。

登录 Controller 

myapp.controller('loginController', function($scope, $rootScope, loginFactory, $localStorage, $sessionStorage, $location) {

            $scope.getUser = function(){
            console.log("Entered getUser controller")
            var user_repack = {
                email: $scope.user.email,
                password: $scope.user.password
            }
            loginFactory.getUser(user_repack, function(data){
                $location.path('/dashboard')
                $rootScope.users = data
                console.log($rootScope.users, "rootScope")
            });
        }

        $scope.logout = function(){
            console.log("Logged out");
            for (var i in $rootScope) {
                if (i.substring(0,1) !== '$') {
                    delete $rootScope[i];
                }
            }
            $location.path('/')
        }
    })

注销功能是在这个之前回答过的问题的帮助下完成的 How to reset $rootScope?
