help with JS

[dugindog]

Can someone familiar with JS please help me with something that I think will be simple.

I want to be able to pass 1 extra parm ie: catagory=widgits
into the data passed to the ajax.php, once its there I'm ready just don't know how to pass the extra variable.

thanks in advance.

<script src="js/prototype.js"></script>
	<script src="js/scriptaculous.js"></script>
	<script>
		Event.observe(window,'load',init,false);
		function init() {
			Sortable.create('listContainer',{tag:'div',onUpdate:updateList});
		}
		function updateList(container) {
			var url = 'ajax.php';
			var params = Sortable.serialize(container.id);
			var ajax = new Ajax.Request(url,{
				method: 'post',
				parameters: params,
				onLoading: function(){$('workingMsg').show()},
				onLoaded: function(){$('workingMsg').hide()}
			});
		}
	</script>

Not being familiar with prototype I'd take a guess at parameters being the data member that carries post information.

As such

parameters: params + "&catagory=widgits",

I'd also advice that you double check that string for spelling errors, as I'd have written those words "category" and "widgets" respetively.
