Accessing Global Function Pointer from its Name

[anoop.kn]

Is there anyway to access Global Function Pointer from its name ?
I want to call the function at runtime during a script execution.
PS: eval() works, I looking for a more efficient way of doing the
same !

Ex:

function testfunction ( msg )
{
alert( msg );
}

function onclickCallback( )
{
var fname = "testfunction";
/*
I want to call the function testfunction here by having access to its
name
without the use of eval. Is it possible ?
*/
}

Since global functions are properties of the global object, and the
global object is "window" (at least in browsers),
window[functionname](); should work.

That leaves us with the question of why you'd need the name at all since
you can refer to functions directly (which /should/ be more efficient):

function Bla() {
alert();
}

var f = Bla;

f();

window[fname]("hello world");
