Angularjs 如何调用声明到控制器中的函数并需要将其调用到app.run块中？

我已经在pageChanged中编写了一个函数，并将其转换为控制器。我必须将此函数调用到app.run块中。我提到的参数是$rootScope、$scope等。 它给我的错误是类型错误。 当我试图在app.run块中实现浏览器后退按钮的逻辑时，它给了我一个错误。 我的代码中通过注释提到了错误行。 我的代码在这里：

var app=angular.module('myApp', ['ngRoute','ngCookies','ui.bootstrap','ui.router','ngStorage']);
    console.log("in appnew.js")

    app.config(function($routeProvider,$locationProvider,$httpProvider) {
        $locationProvider.html5Mode(true);
        $routeProvider
        .when('/',{
            templateUrl:  'login_admin.html'

        })

        .when('/add',{
            templateUrl: 'add_brands.html',
            controller: 'dashCtrl',
            authenticated: true,
            reloadOnSearch: false

        })



        .otherwise({
            redirectTo: "/"
        });
    });


    app.factory('userModel', function($http,$cookies,$location){
        var userModel={};

        userModel.login= function(loginfrm){
          console.log("loginfrm"+loginfrm.user_name);
          $http.post("http://.............../admin_login",loginfrm).
          success(function(response){
            if (response.success == 1) {
                console.log("Password Matched");
                $cookies.put('user_name',loginfrm.user_name);
                $cookies.put('token',response.token);
                $location.path('/dashboard');
            } else if (response.success == -1) {
                console.log("Password Not Matched");
            } else {

            }

           console.log("response success: %j",response)

          });

          }
          else{
            return false;
          }
        };
        console.log('userModel.getAuthStatus'+userModel.getAuthStatus());
        userModel.doUserLogout = function(){

如果我正确理解了您的问题，我可以想到的一种方法是将pageChanged函数附加到控制器中的$rootScope，如下所示

angular.module('app')
    .controller('AppController', function ($rootScope){
        $rootScope.pageChanged = function(){
            <your_code> 
        }  
});

然后将$rootScope注入app.js中的app.run块，并将pageChanged函数调用为$rootScope.pageChanged

但是，除非您共享一个代码片段，否则很难知道这是您要求的还是导致您提到的错误的原因。

共享代码会很有帮助如果在应用程序运行时创建控制器，为什么不在创建控制器时调用该函数呢？@JEETADHIKARI是对的，你们需要在我的代码中发布你们的代码。当我按下浏览器返回按钮时，我无法调用pageChanged方法。我能有什么解决办法吗。。！你好@ami91我已经添加了我的代码。请看一看。在我的代码中，当我按下浏览器后退按钮时，我无法调用pageChanged方法。我能有什么解决办法吗@sumitkumar您是否尝试将“dashCtrl”控制器中的pageChanged函数附加到$rootScope而不是我在回答中提到的$scope？我看到您已将该函数附加到控制器中的$scope，但您正在使用$rootScope从app.run调用它。这将不起作用，您将看到类似UncaughtTypeError的内容：$rootScope.pageChanged不是函数。这就是你看到的错误吗？
