• Patrick Q: @Cerbrus The answer in the question of which you marked this a duplicate is what the OP says he can do already. So while this is a very poor question (OP should have at least tried the obvious), I don't think it's a duplicate of the question that you selected, as that question (and its marked answer) do not address passing parameters.

Answer 1

You can pass arguments to your function where you call window[aa]() like so:

function myfunction(text){
 alert(text);
} 
var aa= "myfunction"; 
window[aa]("Hello Again..."); // just put any arguments in the parentheses.

Answer 2

Just pass it in:

window[aa](param)

• Inspector Squirrel: He only has 48k @Cerbrus, why would you think he'd know better? :/

Answer 3

Can you just put the parameter between the parentheses when you call the function?

window[aa]("Hello, world");

Answer 4

use this:

 function myfunction(param){
 alert(param);
 }
 var aa= "myfunction"; 
 window[aa]('mk');
