How to call global function having its name?

[szimek]

Hi!

In an app which I'm trying to fix to work with FF there's a lot of
code like eval("function_name();"). I remember that there's some way
to call global functions using window object, but I can't get it to
work. Here's what I tried (in Firebug console):

function a() {alert("a called")};
a(); // works
eval("a();"); // works
window["a"](); // doesn't work
TypeError: window.a is not a function

window.b = function() {alert("b called");}
window["b"](); // works

So how can I call global functions in other way than using eval?

Thanks in advance

Running this code in the firebug console is not the same as running it
in the browser window.

Try creating a local file with your code and opening it in FF and
you'll see that it works fine.

?? that works with my Firefox


function b() { alert('yes ? who calls me ?'); };
window['b']();

So how can I call global functions in other way than using eval?

/* this bellow also works for me */

var a = function() { alert('yes ?'); };

window['a'](); // works



to call a function (global) :

<a href="#" onclick="a(); return false;">test</a>

Why to want more ?
