Ruby on Rails file containing both Ruby code and JavaScript; similar to a .RHTML page, but allows Ruby code to be embedded within JavaScript functions; requires a Ruby engine on a Web server to be parsed correctly.
RJS files can be viewed in a Web browser, but the Ruby code is parsed on the Web server before the page is sent to the client. Therefore, the user only sees the HTML and JavaScript code.
Custom skin or theme for the RealJukebox media player; can be applied to the player to alter the look and feel of the interface.
NOTE: There is a known security issue with RJS files that may allow a script to be run when the file is opened. Therefore, do not open an unknown RJS file.
