I am new to Ionic and was wondering if there is a way to dynamically set a global variable and then have it for the rest of the app.
I have an app where on home page I ask user for Phone number and then verify their identity. Once verified I need to store/remember/retrieve for the rest of the app.
Is there a way I can do that rather than passing around it as a parameter?
You can use localStorage to save the phone number :
$window.localStorage.setItem("phoneNumber",phoneNumber);
$window.localStorage.getItem("phoneNumber");
You should be managing your state in a service (ionic calls them providers, generate one with 'ionic generate provider').
The official tutorial 'Tour of Heroes' covers this. You can find the appropriate section here https://angular.io/docs/ts/latest/tutorial/toh-pt4.html.
basically you create a service:
@Injectable()
export class MyService{
public phoneNumber;
}
and use it from all your components like this:
export class MyComponent{
constructor(private myService: MyService){}
setPhone(number: number){
if(validateNumber(number)){
this.myService.phoneNumber = number;
}
}
}
