无法使用打字稿访问在一个控制器中声明的$ rootscope属性在另一个控制器中声明的角度 [英] unable to access $rootscope property declared in one controller in other in angular using typescript

问题描述

我已经在如下所示的ts文件中声明了rootscope自定义属性

I have declared a rootscope custom property in a ts file like below

module MyApp.Entity{

    export interface IRootScope extends ng.IRootScopeService {
        userData: any;
        clientData: any;
    }
} 

在我的一个服务文件中，我已分配了值

In one of my service file I have assigned value

    export class Service1 {

            constructor(private apiService: MyApp.Common.Services.apiService, private notificationService: MyApp.Common.Services.notificationService,
                 private $base64: JQueryBase64Static, private $cookieStore: ng.cookies.ICookieStoreService, private $rootScope: MyApp.Entity.IRootScope) {
            }

    saveData(){
    this.$rootScope.clientData = clientData; // Data got assigned 


    }
}

现在在其他Controller文件中，我正尝试访问该rootscope属性

Now in other Controller file I was trying to access this rootscope property

class controller2{
Clients: any;
constructor(private service1: MyApp.Service.Service1, private $rootScope: MyApp.Entity.IRootScope){
this.Clients = this.$rootScope.clientData; // clientData is Undefined i.e here //it is creating new rootscope again I guess ..so How to access a single global //rootscope
}
  }

推荐答案

您正在使用this.$rootScope，它是$ rootScope的另一个实例，因为只有删除this.后，它才在当前作用域中定义

You are using this.$rootScope which is a different instance of $rootScope since it is only defined in your current scope if you remove the this. it should work
