Jquery

You can send more info to the autocomplete script:

		$("#quesfrom").autocomplete({
			source: function(request, response) {
				$.getJSON("../tm/smcompl.php", {
					term: extractLast(request.term),
					course: document.getElementById("numques").value + 'duck'
				}, response);
			//$.getJSON("../tm/smcompl.php", {term: extractLast(request.term)}, response);
			},
