JavaScript, running in a browser, under normal security conditions, cannot access the user's file system.

You need to have ajax or something else that can write to the server with the right permissions to write to a log file on the server. The JavaScript itself can not write a log file to the server or the client as it is executed off the server and it does not have access to the clients computer (Image getting viruses through JavaScript if this was true)....Unless you give explicit write access which is very unsafe and very complicated to do.
