Is there a way to make a variable classname in javascript. In php the next is allowed:
$classname = "klasse";
$class = new $classname();

If you want to play with globals, then just remember they are all properties of the window object.
… but don't play with globals.
Your particular example:
var $classname = "klasse";
var $class = new window[$classname]();
(Obviously, the usual conventions for only using $ in machine generated code should apply too)

Bear in mind that "eval is evil", but if you are aware of this, then:
var classname= "klasse";
eval( "var obj = new " + classname + "();");

@David (author of a deleted comment that stated that
eval shouldn't be used), that's why I added the disclaimer. However, the question sounds more theoretical than soon to be put to practical use.If you want to call something like
new acme.tools.Hammer();
Then do
var $toolName = "Hammer";
var myObject = new window['acme']['tools'][$toolName]();
