My site content is called from external AJAX files and I need to be able to use jquery is some of these external files. index.php: <script type="text/javascript"> ajax_loadContent('news3','external/home.php'); </script> Code (markup): and in 'home.php' I have (for example) the html for a jquery script, BUT, the jquery code is still in the index.php <head> portion, so nothing gets called. such as this: <link href="css/galleria.css" rel="stylesheet" type="text/css" media="screen"> <script type="text/javascript" src="js/jquery.galleria.js"></script> <script type="text/javascript"> jQuery(function($) { $('ul.gallery').galleria(); }); </script> Code (markup): How can I mix these two languages?
