This can be done fairly simply using an oop approach.
With out going into to much detail. You can create a single instance of a
storage class that gets/sets the data that you are looking for.
Here is a really basic example:
package com.login{
// do some imports
public class myLogin{
private var username:string = new String();
private var email:string = new String();
public function myLogin(){
// do some constructor stuff here
}
public function getUsername():String{
return username;
}
public function getEmail():String{
return email;
}
public function setUsername(username:string):void{
// set your username
}
public function setEmail(email:string):void{
// set your email
}
}
}
So when you first instantiate your class you set the username/email. Then all
you will need to do is use getUsername/getEmail to retrieve the data that you
are looking for.
One last point make sure you that only instantiate the myLogin class once.
