BBQ
in Using jQuery Plugins

Thank your for your last reply Jay Blanchard.
I have since downloaded an example of Ben Alman's BBQ "basic hashchange". It works as expected, but I am having trouble integrating it with my project (so what else is new?).
I've stripped the example-code down a little (see code below) and think I have grasped the basic idea.
To clarify my problem : I need to manipulate several other elements on the main-page (index-page), for example to change the content of a div (let's say #backgroundPict) each time an AJAX call is made (either from scratch or from cache).
So the question is : Whereabouts in the example-code can I experiment with this? I've tried justabout everywhere!
Example code:
$(document).ready(function() {
$(function (){
// Keep a mapping of url-to-container for caching purposes.
var cache = {
// If url is '' (no fragment), display this div's content.
'': $('.bbq-default')
};
// Bind an event to window.onhashchange that, when the history state changes,
// gets the url from the hash and displays either our cached content or fetches
// new content to be displayed.
$(window).bind( 'hashchange', function(e) {
// Get the hash (fragment) as a string, with any leading # removed. Note that
// in jQuery 1.4, you should use e.fragment instead of $.param.fragment().
var url = $.param.fragment();
// Remove .bbq-current class from any previously "current" link(s).
$( 'a.bbq-current' ).removeClass( 'bbq-current' );
// Hide any visible ajax content.
$( '.bbq-content' ).children( ':visible' ).hide();
// Add .bbq-current class to "current" nav link(s), only if url isn't empty.
url && $( 'a[href="#' + url + '"]' ).addClass( 'bbq-current' );
if ( cache[ url ] ) {
// Since the element is already in the cache, it doesn't need to be
// created, so instead of creating it again, let's just show it!
cache[ url ].show();
} else {
// Create container for this url's content and store a reference to it in
// the cache.
cache[ url ] = $( '<div class="bbq-item"/>' )
// Append the content container to the parent container.
.appendTo( '.bbq-content' )
// Load external content via AJAX. Note that in order to keep this
// example streamlined, only the content in .infobox is shown. You'll
// want to change this based on your needs.
.load( url, function(){
});
}
})
// Since the event is only triggered when the hash changes, we need to trigger
// the event now, to handle the hash the page may have loaded with.
// $(window).trigger( 'hashchange' );
});
});
