string as function ?

[Pier25]

Hello!

I have an XML for the items on a menu. I'd like each item call a different function, and have the function name written on the xml.

How would you approach this? Something like (my_str as function) or maybe using eval??

Regards

Pier

After investigating a bit I've found that eval no longer exists in AS3... so for now I'll have to do an ugly switch/case... :S

If anybody knows a better way, please tell me!

You can always call functions by names like this: functionOwnerObject["functionName"](function arguments).
There's also a Deval library for AS3 here: http://riaone.com/products/deval/index.html
But for the task like the one you have you'd hardly need it

Isn't this a perfect match for namespaces ?

var call:String='publicFunction';
var param1:int=3;
var param2:int=6;
this[call](param1,param2);

Thank you for your help guys, this is exactly what I needed

You think so?

[Pier25]

omg I thought that would be easy...

Tried it but this is what I get

ReferenceError: Error #1069: Property abre_contacto not found on master and there is no default value.

abre_contacto being the function I want to call, and master the name of the document class.

var nombre_funcion:String = "abre_contacto";		
this[nombre_funcion]();

edited: sorry, I mismatched the name of the function..... I need some more cofee... thanks anyway!

the object prior to [] (you're using this now) is the reference used to find the function you want to call. If abre_contacto is defined in 'this' then the above code is correct. Otherwise you need a reference to where abre_contacto really is.

Yes, the code was right but the function name was wrong... thx anyway
