How to change a class's content using jQuery
<p>Here is the div element on my page:</p>

<p></p>

<p>How can I change a class's content?</p>

<p>So from existing which is: class="jcarousel-next jcarousel-next-horizontal"</p>

<p>to class="jcarousel-next jcarousel-next-horizontal jcarousel-next-
disabled jcarousel-next-disabled-horizontal"</p>

<p>Do I need to completely remove it by using removeClass and then re-add?</p>
