main.window() or what?
I wrote some JS code, but I can´t anything out. I just goes blank. Is it because I don´t have a main functions for my functions?

Test to see if any JavaScript errors are occurring. In some browsers, once a JavaScript error takes place, script execution stops. In fact, I see some errors just by inspecting your code (you call antalAr before it has been declared)
Edit:
In IE, the for(int i=-1; i<13; i++) line is where the first error occurs. (int is not valid in JavaScript). Replacing int with var allows the script to run on my machine.
I'd recommend using IE with script debugging enabled or Firebug during any JavaScript development.
