Replace content with ajax content

I would like to have something like this work

`<div id=”ajaxID”>

<?php the_content();?> <!– display this onload, but replace this with ajax content when link is clicked–>

</div><!–endofAjaxID–>

When I try to do this now, when I click the link on the home page that leads to this I only get the section of the page within the id of ajaxID when I reload the page the rest of the page loads and works as i would like it to.

Is there a way to have the ajax content replace other content when activated?

Thanks,

Zach
