javascript - Loading content with ajax while scrolling

Question

I'm using jQuery Tools Plugin as image slider (image here), but due to large amount of images I need to load them few at a time. Since it's javascript coded, I can't have the scroll position as far as I know. I want to load them as soon as the last image shows up or something like that. I have no idea where I put and event listener neither anything.

Here is my code http://jsfiddle.net/PxGTJ/

Give me some light, please!

Answer 1

I just had to use jQuery Tools' API, the onSeek parameter within the scrollable() method.

It was something like that

$(".scrollable").scrollable({
    vertical: true,
    onSeek: function() {
        row = this.getIndex();
        // Check if it's worth to load more content
        if(row%4 == 0 && row != 0) {
            var id = this.getItems().find('img').filter(':last').attr('id');
            id = parseInt(id);
            $.get('galeria.items.php?id='+id, null, function(html) {
                $('.items').append(html);
            });
        }
    }
});
