create a new class using a string name in typescript [duplicate]

Question

I am writing an XML loader/parser (and new to typescript), I can load the XML fine, however I'm trying to dynamically parse the XML data back into a class/object. The problem is, I would like to create a class using a string variable; ie var classNameString:String = "className";

var newClass:any = new class(classNameString)

from my many searches of the internet it doesn't appear possible, and I'm going to have to hardcode the class names. Any help would be greatly appreciated.

Answer 1

If you have a specific namespace, for all the class you want to create, you can do this:

var newClass: any = new (<any>MyNamespace)[classNameString](parametersIfAny);

and if they are in the default namespace you can simply use window:

var newClass: any = new (<any>window)[classNameString](parametersIfAny);

Update

You now need to have the <any> cast with latest TypeScript or you get an Error TS7017 Build:Element implicitly has an 'any' type because type '{}' has no index signature.
