userService在根级别注册。
我想在's中获得getUserLogin可观察的价值。当用户单击按钮时，将值从.SharedModuleUserComponentHomeComponentHomeModule
UserService在根级别：
userLogin = new Subject<string>();
constructor() { }
sendUserLogin(user: string) {
console.log("value received at user service ", user);
this.userLogin.next(user);
}
getUserLogin(): Observable<string> {
return this.userLogin.asObservable();
}
HomeComponent在HomeModule：
export class HomeComponent implements OnInit {
constructor(private userService: UserService) {
}
ngOnInit() {
}
onClick() {
console.log("value is send from home component", "Nilesh")
this.userService.sendUserLogin("Nilesh");
}
}
UserComponent在SharedModule：
export class UserComponent implements OnInit {
constructor(private userService: UserService) { }
ngOnInit() {
this.userService.getUserLogin().subscribe(res => {
/// here it should receive but not able to get it
console.log("user component should get value here ", res);
});
}
}
