Use string to access object in Javascript

Question

I have a variable containing a string "Y.Plugin.abcd" and I would like to access an object with the same name...I'm using YUI 3 and attempted the Y.namespace method with no luck.

var nm = "Y.Plugin.abcd";

Y.log(Y.Plugin.abcd); //outputs the correct object

Y.log(Y.namespace(nm)); //outputs an empty object

I'm pretty much looking for any method, YUI or not, to be able to do what is a rather simple task in PHP.

In plain JavaScript, you could probably split your string and then use the subscript notation, as follows:

var nm = "Y.Plugin.abcd";
var nm_array = nm.split('.');    // split the nm string
var obj = window;                // set our reference to the global object

for (var i = 0; i < nm_array.length; i++) {
   obj = obj[nm_array[i]];       // walk through all the namespaces
}

Y.log(obj);                      // obj will hold a reference to Y.Plugin.abcd
