Thanks techneke, but maybe I have not explained well. :-S

I need create a JavaScript file with a ".js" extension, but with the "views of CodeIgniter" only is possible output a result without extension and executed in own server.

With a CI view now i get:
http://www.domain.com/order

And i want get:
http://www.domain.com/order/js_file_name.js?id=11111 (o similar..) and changing his content by calling to database with this id passed.

For i can to give to users this js file, to embed this in his sites once created. And execute it in navigator of user.

It is better explained now?
