Persisting data in a component Angular 6












0















I have 2 component which are communicating with a third.
Those 2 component can send datas in the third component through a service.
It works fine until I change the current route and reach another page ...



My first component is exactly the same as the second :



Parent component :



<app-product class="col-xs-6 col-md-3"
*ngFor="let prod of products"
[product] = "prod"
></app-product>


Child component (light version) :



<span *ngFor="let image of product.images">
<img src="assets/{{ image.url }}" alt="product" class="image">
{{ product.name}}
<button routerLink="product/{{ product.id }}">More info</button>
<button (click)="onAddProduct()">Add</button>
</span>
</span>


My component looks like this :



export class ProductComponent implements OnInit {
@Input() private product: Product;

constructor(private basketData: BasketdataService) { }

ngOnInit() {
}
onAddProduct() {
this.basketData.onAddBasket(this.product);
}
}


My product list is like this :



export class ProductlistComponent implements OnInit {
public id: string;
products: Array<Product> = new Array<Product>();

constructor(private productService: ProductsService, private route: ActivatedRoute) {
this.id = this.route.snapshot.paramMap.get('id');
this.productService.getAll(this.id )
.subscribe(
res => {this.products = res }
)
}
ngOnInit() {
this.id = this.route.snapshot.paramMap.get('id');
}
}
