I have in my code several classes defined using prototype.
var Conversation = Class.create({ (methods) });
var Friend = Class.create({ (methods) });
And I have a variable that can hold an instance of either of both
classes.
var A = new Friend();
Is there a way of checking which type it is?
I'm looking for something equivalent to:
If (A Is Friend) { }
elseif (A Is Conversation) { }
or...
If (typeof A Is Friend) { }
Is there something like that?
I can check for the existence of a member. For example, I know
Conversations have a method called "xxx", and Friends do not, so I can
do:
If (typeof A.xxx != 'undefined') { }
But that's bound to be broken when I add an "xxx" method to Friend.
Plus, I have many different classes a variable can hold, so these
tests can get quite long-winded at times.
Any ideas?
Sorry if this has an obvious answer, I haven't been able to find it.
Thanks in advance!
