Need php script but in javascript.

[tanaxis]

i give a code i made with php and js in one to give you a idea of what i want :

if(isset($_GET['page'])) {
switch(strtolower($_GET['page'])){

case (url='?page=home'): myMenu.expandMenu(myMenu.submenus[0]); document.title='Lazysoldiers - Home'; break;
case (url='?page=Joining'): myMenu.expandMenu(myMenu.submenus[0]); document.title='Lazysoldiers - joining'; break;
case (url='?page=rules'): myMenu.expandMenu(myMenu.submenus[1]); document.title='Lazysoldiers - rules'; break;
case (url='?page=members'): myMenu.expandMenu(myMenu.submenus[1]); document.title='Lazysoldiers -members; break;
case (url='?page=servers'): myMenu.expandMenu(myMenu.submenus[1]); document.title='Lazysoldiers - Home'; break;
case (url='?page=etc'): myMenu.expandMenu(myMenu.submenus[etc]); document.title='Lazysoldiers - etc'; break;
default: myMenu.expandMenu(myMenu.submenus[0]); document.title='Lazysoldiers - Error'; break;
        }
        }
else 
{
myMenu.expandMenu(myMenu.submenus[0]); document.title='Lazysoldiers - Error'; break;
}

So let me explain
if url is http://mydomain.info?page=home
then the mymenu expands "submenu 0" and changes document title to "lazysoldiers - Home"
and so on for the rest, the codei gave was me puttign some php and javascript codes to gether i know that isnt posible but didnt find any options on the internet. Uh it needs to be javascript since mymenu is a javascript script.
