如何刷新Angular.js中的特定控制器（在app.js中）

Question

在Angular.js中刷新特定控制器的最佳方法是什么，我可以检测到这样的页面更改：

//when app runs call this function.
app.run(function($rootScope, $route, $location, $cookies){
   //Bind the `$locationChangeSuccess` event on the rootScope, so that we dont need to 
   //bind in induvidual controllers.

   $rootScope.$on('$locationChangeSuccess', function() {
        $rootScope.actualLocation = $location.path();
    });        

   $rootScope.$watch(function () {return $location.path()}, function (newLocation, oldLocation) {
        if($rootScope.actualLocation === newLocation) {
            console.log('user hit back');
            if($rootScope.actualLocation=='/'){
              //clear cookie
              var testing = $cookies.getObject('globals');
              $location.path('/');
            }
        }
    });
});

我需要刷新我的navigationController，所以如果用户按下后退按钮或刷新浏览器窗口，它会动态保持其状态。

导航控制器：

nav.js

    'use strict';

    //app global variable
    //this is the controller that handles post requests
    //declare services as dependecies $http, $location, custom service apiServiceWeb
    app.controller('navigationController', function($scope, $route, $rootScope, $http, $location, $cookies, setCredentials) {

      //get what is in the cookie
      var cookieValue = setCredentials.getCookie('globals');
      console.log($cookies.get('globals'));

      //hide menu in certain paths 
      if ($location.path() == '/' || $location.path() == 'signup') {
        $scope.isConnected = true;

      } else {

        $rootScope.$watch('globals', function() {
          //if a currentUser does NOT exist, the hide menu.

          if (cookieValue = null) {
            $scope.isConnected = true;
          } else {

            $scope.isConnected = false;

          }

        });

      } 

    });

index.html

这是观点。

  <div ng-controller="navigationController">
          <!-- Navigation -->
    <nav class="navbar navbar-inverse navbar-fixed-top" role="navigation" ng-hide="isConnected">
        <div class="container">
      <!-- Brand and toggle get grouped for better mobile display -->
            <div class="navbar-header">
                <button type="button" class="navbar-toggle" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">
                    <span class="sr-only">Toggle navigation</span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                    <span class="icon-bar"></span>
                </button>
                <a class="navbar-brand" href="#">Start Bootstrap</a>
            </div>
            <!-- Collect the nav links, forms, and other content for toggling -->
            <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
                <ul class="nav navbar-nav">
                    <li>
                        <a href="#">About</a>
                    </li>
                    <li>
                        <a href="#">Services</a>
                    </li>
                    <li>
                        <a href="#">Contact</a>
                    </li>
                </ul>
            </div>
            <!-- /.navbar-collapse -->
        </div>
        <!-- /.container -->
    </nav>
    </div>
    <div ng-view=""></div>
