jQuery Infinite Scroll Plugin

JQuery plugin for ajax-enabled infinite page scroll. There are a lot of jQuery plugins for infinite page scrolling function. However none of them matched my needs when I faced the problem. So this is a very simple plugin which makes ajax call to load more data on the page and gives some basic callbacks like data loading started or data did loaded.

##Usage sample

CoffeScript:

$ ->
	$('#tasks').infiniteScroll
		itemSelector: 'tr.task'
		dataPath: '/tasks/load_more_tasks'

HTML part:

<table id='tasks'>
	<thead>
		<th>ID</th>
		<th>Name</th>
	</thead>
	<tbody>
		<tr class='task'>
			<td>1</td>
			<td>First</td>
		</tr>
		<tr class='task'>
			<td>2</td>
			<td>Second</td>
		</tr>
		...more rows
	</tbody>
</table>

AJAX part: /tasks/load_more_tasks. This should return plain HTML:

<tr class='task'>
	<td>10</td>
	<td>Tenth</td>
</tr>
<tr class='task'>
	<td>21</td>
	<td>Eleventh</td>
</tr>
...even more rows

Options

dataPath - URL to load more data from
