Ionic Angular Passing data between views-CodePudding

I want to create 3 Pages where ;

In page A there's a formgroup, after it fills and click submit btn, then it will go to the Page B.

In Page B there's only a confirmation statement. so user only have to choose Agree or Disagree.

If user choose Agree on Page B then goes to Page C and shown all information/data from Page A.

My question is, is it possible to pass the data(name,email,id) from page A directly to C while the flow of the views must be A > B > C.

Can i achieve this with ionic angular?

You can save the data in a subject inside a service in page A, and subscribe to the subject in page C to receive the data. Same thing can be achieved with ngrx or any other state management library.

Simple example:

data.service.ts

// the service that has the subject that keeps the data
private data$ = new BehaviorSubject<any>(null);

setData(data: any){
  this.data$.next(data);
}

getData(){
  return this.data$.asObservable();
}

page-a.component.ts

submitForm(){
  //...
  this.dataService.setData(this.form.value);
}

page-c.component.ts

ngOnInit(){
  //...
  this.dataService.getData().subscribe(data => {
    // do whatever you want with the data
  }
}

You can create a Static Class to pass your data.

ionic g service globaldata

which you can share data.

inside your page A:

import {GlobalDataServe} from 'GlobaldataServer.ts'

gotoPageB(){
  GlobalDataServe.yourDataVariable = yourDataOnPageA;
  this.route.navigate('yourPageB');
}

Nothing to do on page B;

on page C import same class and get data

import {GlobalDataServe} from 'GlobaldataServer.ts

ionViewWilLEnter(){
 this.yourData = GlobalDataServe.yourDataVariable;
}
