ajax - open ajax page from within an ajax page

Question

We have done a site, that loads content into a div, using ajax. My question is, within that ajax page, can I initiate a new page to load onclick in the existing pages place.

So as it stands on my index page I have:

<section id="mycontent">

</section>

Onclick of a element my content gets loaded into the above section. Like so:

<span class="link_wrap" data-link="prices"><span class="link_title">Our Prices</span</span>

So on click of the above, our js pulls in the relevant page: prices.php

In the JS I have:

case 'prices' :

     myFunctionAjax('prices.php', function () {

         _self._focustitle();

     });

break;

So what I would like to do is, in say the prices.php page have a link to say deals.php

That onclick, similar to above, loads IN PLACE of prices.php content the new content from deals.php.

Any suggestions ?
