Dynamics load content using jQuery plugin

[eluser]Unknown[/eluser]
Hi,
I have an idea for dynamic loading content using jQuery plugin, because I have many clients and websites where I'm using loading content to page elements using Ajax (jQuery).

I can write jQuery plugin for loading pages in CodeIgniter, but I can't write any class (plugin) to the CodeIgniter.

My idea:

1) First step will be an uploading jQuery plugin to js folder (or any other folder name) placed in root.
2) Loading plugin in controller class using code like:

Code:

$this->jquery->load('js/jQuery.load.js');

3) And with <a href="#">...</a> links use the syntax like

Code:

onclick="<? $this->jquery->load('<? echo base_url(); ?>index.php/some_controller','#pageContent'); ?>"

or

Code:

rel="jQuery.load,<? echo base_url(); ?>index.php/some_controller,#pageContent"

Where first (second) parameter will be a page URL to load and second parameter will be HTML element to load content page. And some other parameters like effect while loading etc.

My question is a how can I write any CodeIgniter class for using this plugin?

Thanks a lot for answers...

... sorry for my english ;-) ...
