Refresh periodico di una div - Mootools

[Arry_blu]

niente risolto così:

	     <script type="text/javascript">
	window.addEvent('domready', function() {
	    var periodical;
	    var url = 'http://www.ninjaadventure.netsons.org/chatview.php?id=<?= $id ?>&last=<?= $ultimavista ?>';
		var ajax = new Ajax(url, {
			update: $('chat_view'),
			evalScripts: true
		});
		function myPeriodical(){ ajax.request(); };
               myPeriodical.periodical(15000);
	});
</script>
