如何调用声明到控制器中的函数，并需要将其调用到app.run block中?

Question

我已经在控制器中编写了一个pageChanged()函数。我必须将这个函数调用到 app.run 块中。我提到参数为$rootScope、$scope等。 它给了我错误作为类型错误。 当我尝试在 app.run 块中实现浏览器后退按钮的逻辑时，它给了我错误。 错误行在我的代码中通过注释提到。 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);
$location.path('/dashboard');
} else if (response.success == -1) {
console.log("Password Not Matched");
} else {
console.log("Sorry there is some error");
}
/*console.log('$scope.dynamic1: %j', $scope);*/
console.log("response success: %j",response)
}).
error(function(response){
console.log("response error:",response);
});
};
userModel.getAuthStatus = function(){
var status = $cookies.get('user_name');
console.log('status: %j', status);
if(status){
return true;
}
else{
return false;
}
};
console.log('userModel.getAuthStatus'+userModel.getAuthStatus());
userModel.doUserLogout = function(){
$cookies.remove('user_name');
$cookies.remove('token');
}
console.log("userModel: %j",userModel);
return userModel;
});


app.filter('startFrom',function(){
return function(data,start){
if(data != null) {
//console.log("data fetched");
//console.log('data: %j',data);
return data.slice(start);
}
else if(data == null){ console.log("data is null"); }

如果我正确理解您的问题，我能想到的一种方法是您将 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注入到 app 中的 app.run 块中.js并将 pageChanged 函数调用为 $rootScope.pageChanged((

但是，除非您共享代码片段，否则很难知道这是否是您所要求的，或者这是否是导致您提到的错误的原因。
