Javascript 从具有角度模型的行为主体获取的Getter值

我的服务

        **Assign to data:Group gives error in get function
        Observable<Group>' is missing the following properties from type** 

---

解决了我自己的问题

newGroup = new Group();
  private groupListSource = new BehaviorSubject<Group>(this.newGroup);
  public groupListValue: Observable<Group> = this.groupListSource.asObservable()
  constructor(private storageService: StorageService) { }

  groupItems(data: Group) {
    this.storageService.setLocalStore("groupList", data)
    this.groupListSource.next(Object.assign({}, data));
  }

  get groupList() {
    return this.groupListSource.value;
  }

newGroup=newGroup（）；
private groupListSource=新行为主体（this.newGroup）；
publicGroupListValue:Observable=this.groupListSource.asObservable（）
构造函数（私有存储服务：存储服务）{}
groupItems（数据：组）{
this.storageService.setLocalStore（“groupList”，数据）
this.groupListSource.next（Object.assign（{}，data））；
}
获取组列表（）{
返回此.groupListSource.value；
}

changing data:Group=>data:any解决了我的错误，但需要正确的代码结构，感谢您在初始化

newGroup

属性时忘记了括号，它应该是

newGroup=newGroup（）
    export class Group {
        groupId: string;
        groupName: string;
    }


newGroup = new Group();
  private groupListSource = new BehaviorSubject<Group>(this.newGroup);
  public groupListValue: Observable<Group> = this.groupListSource.asObservable()
  constructor(private storageService: StorageService) { }

  groupItems(data: Group) {
    this.storageService.setLocalStore("groupList", data)
    this.groupListSource.next(Object.assign({}, data));
  }

  get groupList() {
    return this.groupListSource.value;
  }
