本文介绍了如何设置角服务功能内$ rootScope?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我无法设置$ rootScope为Angularjs。

下面是我的功能

  App.controller('控制',
功能(UtilityService,$ rootScope){VAR setSession =功能(){  $ rootScope.test =是; //< - 我得到这个  UtilityService.getSession()。成功(
  功能(){
    $ rootScope.test =否; //< - 我没有得到这个我如何获得/设置这个值?
  });
};setSession();});

其他信息:

一个可能的工作方式是建立被多个控制器之间的交互服务。是否有人知道如何与服务返回一个http.get JSON对象做到这一点。

我有麻烦在我的控制器动态范围,这是一个服务中被实例化。


解决方案

为了解决我的问题,我不得不

1)通$ rootScope到我的第二控


  

App.controller($ rootScope){


2)设置我的第二个控制器的功能$ rootScope


  

$ rootScope.functionCall =功能(){};


3)设置我的传递价值$ rootScope($ rootScope.orderId)


  $ rootScope.functionCall =功能(){
 Service.getItems($ rootScope.orderId).success(
    功能(结果){
      $ scope.items =结果;
    });
};



4)我的效用控制器,I环通我的结果,解析它们,将它们设置为$ rootScope你可以看到在#3中,我初始化$ rootScope.orderId


  angular.forEach(结果,功能(值,键){
      如果(关键!= NULL){
        $解析(键).assign($ rootScope,价值);
      }
    });


5),我从我的服务调用内再呼叫控制器的功能!这是做什么神奇的,我把我的变量范围


  

$ rootScope.functionCall();


6)我也测试,以查看是否存在功能造成不同页面使用的公用code,但可能不具备的功能来执行


  如果

(typeof运算$ rootScope.functionCall =='功能')


  VAR setSession =功能(){  UtilityService.getSession()。成功(
  功能(结果){    //将范围的rootscope会议
    angular.forEach(结果,功能(值,键){
      如果(关键!= NULL){
        $解析(键).assign($ rootScope,价值);
      }
    });    //不得不绕过范围的问题,因此必须执行这些FNS()
    如果(typeof运算$ rootScope.functionCall =='功能'){
      $ rootScope.functionCall();
    }});};
setSession();

I'm having trouble setting $rootScope for Angularjs.

Below is my function

App.controller('Controller',
function (UtilityService, $rootScope) {

var setSession = function () {

  $rootScope.test = "yes"; // <-- I get this

  UtilityService.getSession().success(
  function () {       
    $rootScope.test = "No"; // <-- I don't get this How do I get/set this value?       
  });      
};

setSession();   

});

Additional Info:

One of the ways that might work is to set up a service that is interacted between multiple controllers. Does anybody know how to do this with the service returning an http.get json object.

I'm having trouble getting a dynamic scope in my controller that is instantiated within a service.

解决方案

In order to address my issue I had to

1) Pass $rootScope into my 2nd controller

App.controller($rootScope) {

2) Set my 2nd controller's function to $rootScope

$rootScope.functionCall = function () {};

3) Set my passed value to $rootScope ($rootScope.orderId)

$rootScope.functionCall = function () {
 Service.getItems($rootScope.orderId).success(
    function(results) {
      $scope.items = results;
    });
};


4) within my utility controller, I loop through my results, parsing them, and setting them to $rootScope as you can see in #3 I am initializing "$rootScope.orderId"

angular.forEach(results, function (value, key) {
      if (key != null) {
        $parse(key).assign($rootScope, value);
      }
    });   

5) I am re-calling the controller's function from within my service call! This is what did the magic for me putting my variable "in scope"

$rootScope.functionCall();

6) I am also testing to see if the function exist cause different pages utilize the utility code but may not have the function to execute

if (typeof $rootScope.functionCall == 'function')

var setSession = function () {

  UtilityService.getSession().success(
  function (results) {             

    // Place the rootscope sessions in scope
    angular.forEach(results, function (value, key) {
      if (key != null) {
        $parse(key).assign($rootScope, value);
      }
    });                

    // Have to bypass "scope" issues and thus have to execute these fns()
    if (typeof $rootScope.functionCall == 'function') {
      $rootScope.functionCall();
    }

});

};
setSession();
