I was trying to get PJAX working with my PHP site, this is the code I am using for it:

<script src="js/jquery.js"></script> 
<script src="js/jquery.pjax.js"></script>
    <script type="text/javascript">
        $(function(){
            // pjax
            $('ul a').pjax('section')
        })
    </script>

I am just using the code they used on the PJAX demo page, but replacing the container they used (#main) with the one for my site, which was the section tag. There are no errors on the console or on the page, but it doesn't work either! Before I was using

$(function() { $('ul a').pjax('section') }); and

$('document').ready(function(){
   $('ul a').pjax('section')
});

But when I don't use either of those and just use $('ul a').pjax('section') I see this error in the console:

Uncaught no pjax container for section in jquery.pjax.js (line: 353)

Could I get some help with this? Thanks
