The basics of our module are going to be mostly the same as in our previous
module. In fact, I've prepared a basic module installation with only the basic
files. You can find it in the code bundle, and it is called
mod_tinynews.tar.gz.
As always, our first step will be to install this file. But before continuing, and just to make sure we don't forget about it, we will go to the administrator screen, navigate to Extensions | Plugin Manager and open System - SC jQuery plugin.
Make sure that the plugin is also enabled for the backend, as we can see in the following screenshot:
We have been using this plugin in the book, mostly for the frontend of our site. However, we can also use it in the backend for our module's admin zone. Enabling the plugin for the backend will let us use the power of jQuery on the administrator screen.
