Call namespace Function from Strings

Question

Now I use this method to call functions inside a Namespaces:

eval('Admin.' + section + '.' + action + '()');

But I don't like use eval, I need to call methods in different namespaces creating the call using string given me from JSON, but I think this is not good system, because eval it's dangerous.

Any other form to make this works? Thanks!

You can use the [] operator to do that:

Admin[ section ][ action ]();
