setup remote javascript debugging

Hi,

i'm trying to setup a javascript debug configuration for a webapp using an MVC pattern.
The app uses a front controller to route the request to the appropriate controller, using a get parameter.

An example url would be the following:
http://myapp.com/?controller=myController

Smarty templates are used in this app, so there's no real html page, the html code is generated on the fly by Smarty.
The javascript code is attached to these templates.

So since there is no path to specific html page, how do I have to setup the javascript debugger in order to work ?
