@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. — Patrick Q

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.

Just pass it in:

window[aa](param)

Really? A answer instead of a close-vote?

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

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

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

use this:

 function myfunction(param){
    alert(param);
 }

    var aa= "myfunction";  
    window[aa]('mk');
