AngularJS - 无法访问RootScope [英] AngularJS - Cannot access RootScope

问题描述

奇怪的问题，
我无法访问在在CTRLA越来越设置CTRLB变量$ rootScope。

Strange problem, I cannot access the $rootScope in CtrlB variable that is getting set in CtrlA.

HTML

<div role="main" class="container_9" ng-controller="CountryCtrl" ng-init="updateToken('<?php echo $TOKEN; ?>')">  

CTRLA

app.controller('CountryCtrl', function ($scope,$rootScope, $http) {
  $scope.updateToken = function(token) {
        $rootScope.token = token;
  } 
});  

CTRLB

app.controller('DealerListCtrl', function ($scope, $http, $rootScope, dealerService) {
  $scope.dealer = [];
    $http.get('files/framework/dealer/'+ $rootScope.token).success(function(data) {
        $scope.dealerall = data;
    });
  //$scope.dealerall = dealerService.api.get({token: $scope.token});
  $scope.orderProp = 'name';

});  

错误消息：

/framework/dealer/undefined 500 (Internal Server Error)   

我是什么做错了吗？

What am I doing wrong?

推荐答案

它访问 $ rootScope 就好了。如果不是你会得到约$ rootScope JavaScript错误没有被定义的。相反，它的套结不确定到请求的URL的结尾，这意味着 $ rootScope.token 是不确定的。做任何你需要确保 $ rootScope.token 定义。

It's accessing the $rootScope just fine. If it wasn't you'd be getting a javascript error about $rootScope not being defined. Instead, it's tacking "undefined" onto the end of the request URL, meaning $rootScope.token is undefined. Do whatever you need to to make sure $rootScope.token is defined.

我怀疑CTRLB获取调用之前CTRLA，所以 $ rootScope.token 还没有确定呢。

I suspect CtrlB is getting called before CtrlA, and so $rootScope.token hasn't been set yet.
