jquery infinitescroll

A demo page is currently here

Usage

<script src="<some_path>/jquery.min.js"></script>
<script src="<some_path>/jquery.infinitescroll.js"></script>
<script>
    $('.row').infinitescroll({
        itemSelector: '.col',
        nextSelector: '.next-page',
        bufferPx: 40,
    });
</script>

An Ajax call takes place when the first element matching the nextSelector comes closer to the window bottom than the pixels defined in bufferPx during scrolling.

The Ajax call fetches that page which is defined in the href of the first link matching nextSelector.

The elements of the fetched page matching itemSelector are appended to the jQuery collection.

If the next page has an element matching nextSelector as well, the whole procedure repeats.
