[kad333r]

$( document ).ready(function() {

	$('.mountakhab .load-section').jscroll({
			debug : true,
		    nextSelector: '.mountakhab-link a',
		    contentSelector: '.category-articles-list'
	});


	$('.botola-pro .load-section').jscroll({
			debug : true,
		    nextSelector: '.botola-pro-link a',
		    contentSelector: '.category-articles-list'
	});
});
