I have a dilemma in Angular where I need to work with two objects of the same type.
public addressFinalData: AddressMailingData;
mailingArchive: AddressMailingData[] = [];
Is there a way to subscribe to data objects of the same type within one component?
I would like for mailingArchive[2] to continuously update its value to match that of addressFinalData. In other words, whenever addressFinalData changes, I want MailingArchive to store that updated value in index 2 of the array.
If you want to manipulate the AddressMailingData, you can use observables and update the value in the subscription.
public addressFinalData = new Subject<AddressMailingData>();
mailingArchive: AddressMailingData[] = [];
ngOnInit() {
this.addressFinalData.subscribe(
(val: any) => {
this.mailingArchive[2] = val;
}
)
}
To update the value of addressFinalData, make sure to emit the data using the next method.
this.addressFinalData.next({newData});
