For a start there's http://video.derekallard.com/. Then you might want to check out some of sample applications - quite a few of those have ajax functionality.

In my personal opinion however, you shouldn't learn ajax on codeigniter, it just adds another layer of complexity. The way I learned was just a simple one page script such as this:

Code:
&lt;?php

// This is our 'backend'

if(isset($_POST['ajax'])) {

    echo 'ajax works :D';

    exit;

}

?&gt;

&lt;html&gt;

    &lt;head&gt;

        &lt;title&gt;Ajax Test&lt;/title&gt;

        &lt;script src="/prototype.js" type="text/javascript" charset="utf-8">&lt;/script&gt;

        &lt;script type="text/javascript" charset="utf-8"&gt;

        &lt;!--

            init = function() {

                $('callthatsucker').observe('click', ajaxify);

            }

            ajaxify = function(event) {

                event.stop();

                var url = '';    //Self submit

                new Ajax.Request(url, {

                    method: 'post',

                    parameters: {ajax: 'true'},

                    onSuccess: function(transport) {

                        $('content').update(transport.responseText);

                    }

                });

            }

            document.observe('dom:loaded', init);

        //--&gt;

        &lt;/script&gt;

    &lt;/head&gt;

    &lt;body&gt;

        <div id='content'>Ajax not called yet :(</div>

        <a href='www.google.com' id='callthatsucker'>Ajaxify me</a>

        <div>If that link goes to google, something went wrong</div>

    &lt;/body&gt;

&lt;/html&gt;

Basically all your ajax calls self submit, that way you have your backend right there and don't go switching files looking for stupid little bugs. In fact, I still develop my javascript this way and plug it into the application when I know it works.

Make sure to get a decent grounding in javascript and it's screwed up syntax before attempting ajax stuff, it'll make your life easier in the long run.
