I try to execute a for each in my ngOnInit
method (i use Angular 4+). But it doesn't perform
there is my code :
export class ObjectDetailComponent implements OnInit {
public object$: Object ;
private member$: Object ;
private _sellers = [];
private _seller: string;
constructor(private route: ActivatedRoute, private _cookieService: CookieService,
private _objectService: AuctionedObjectService, private _memberService: MemberService, private _sellerService: SellerService) {
this.route.params.subscribe( params => this.object$ = params.id );
}
ngOnInit() {
this._objectService.getObject(this.object$).subscribe(
data => this.object$ = data);
this._memberService.getMember(Number(this._cookieService.get('login')))
.subscribe(data2 => this.member$ = data2);
this._sellerService.getSellers()
.subscribe(data3 => this._sellers = data3);
this.sellerUser();
}
public sellerUser(){
for(const seller of this._sellers){
if(Number(this._cookieService.get('login')) === seller.idUser){
this._seller = seller.username;
break;
}
}
}
}
The sellerUser()
doesn't work :/
Use your synchronous logic after you are sure you have got the result, use this.sellerUser();
under your Subscripition
. In your current implementation, this.sellerUser();
will get called before your subscription is over(coz subscription is async and will be executed at last after executing all your sync code)
this._sellerService.getSellers()
.subscribe(data3 => {
this._sellers = data3;
this.sellerUser(); // here
});
