JavaScript running in the browser does not have any commands for reading or writing files. JavaScript is a client-side language; modern browsers can read files on the server using an Ajax call, but otherwise JavaScript has no capability to read from, write to or delete a file (except a cookie), communicate with the server, access a database, the client's operating system or the Windows registry, or alter the default behaviour of the browser.

MSIE can write to files ON THE USER'S COMPUTER (only), but only if the user marks your site as being a "safe" site and only if he/she agrees to let your page run an "unsafe for scripting" ActiveX control.

So to write data to a file you will need to use server-side scripting.
