node.js - AngularJS 数据绑定(bind)的问题

Question

大家好，我遇到了数据绑定(bind)问题。多年来，我一直试图弄清楚为什么我的少数人无法访问服务提供的 global.user。有人能弄清楚发生了什么事吗？预先感谢。最好的问候托马斯

个人资料.html

<section data-ng-controller="MyprofileController">
<h1>{{global.current_User()}}</h1>
</section>

myprofile.js

'use strict';

angular.module('mean.system').controller('MyprofileController', ['$scope', 'Global',         function ($scope, Global) {
$scope.global = Global;
$scope.test = 'testcase';}]);

服务

'use strict';

//Global service for global variables
angular.module('mean.system').factory('Global', [
function() {
    var current_user = window.user;
    return {
        current_User: function() {
            return current_user;
        },
        isloggedIn: function() {
            return !!current_user;
        }
    };
}

]);

非常感谢您的帮助。

刚刚发现 Firefox 确实打印了一条错误消息!

它应该可以工作，并且在我创建的 fiddle 中也可以:http://jsfiddle.net/BernhardW/mLQWs/

window.user = 'John Doe';

angular.module('mean.system', []);

angular.module('mean.system').controller('MyprofileController', function ($scope, Global) {
    $scope.global = Global;
    $scope.test = 'testcase';
});

angular.module('mean.system').factory('Global', function() {
    var current_user = window.user;

    return {
        current_User: function() {
            return current_user;
        },
        isloggedIn: function() {
            return !!current_user;
        }
    };
});

是否有任何错误显示？
