I used the data service to set the value on a onclick event new tab opens
up and subscribe in the child i.e and pop up tab , However the data service
returning value as in defined.
what is that I am missing, Your response is highly appreciated.
@Injectable()
*export* *class* DataService {
*private* selectedCustomer: Subject<CustomerLoginVo> = *new* BehaviorSubject
<CustomerLoginVo>(*null*);
customerClickedOn = *this*.selectedCustomer.asObservable();
*private* selectedOrders: Subject<OrderItemVo[]> = *new* BehaviorSubject<
OrderItemVo[]>(*null*);
selectedCustomerOrders = *this*.selectedOrders.asObservable();
*constructor*() { }
setSelectedCustomer(customerSelected: CustomerLoginVo) {
*this*.selectedCustomer.next(customerSelected);
}
setOrders(orders: OrderItemVo[]) {
*this*.selectedOrders.next(orders);
}
}
-----------------------------------------------------
This is the parent component setting the value
*this*.dataService.setOrders(*this*.orders);
-------------------------------------------------------------
This is in the pop up component
ngOnInit() {
console.log ('On Init in Print is called');
*this*.getOrders();
console.log ('On init Print is called'*+t**his*.orders);
}
ngOnChanges() {
console.log ('On Changes in Print is called');
*this*.getOrders();
console.log ('On Changes in Print is called'*+t**his*.orders);
}
getOrders() {
*this*.customerInfoDataService.selectedCustomerOrders.subscribe(customerOrders
=> {
*this*.orders = customerOrders;
console.log ('getOrders is called'*+c*ustomerOrders);
}, err => {
console.log(err);
});
}
-----------------------------------------------------
Please let me know you response.
