[SOLVED] Autocomplete search as you type

I changed the url, to this, still not working. Anyone sample code where AJAX is used the correct way will help…

thanks

$("#autocomplete").autocomplete({
                source: function(request, response) {
                    $.ajax({
                        url: '/fetchdata'
                        type: 'POST',
                        {#dataType: 'json',
                        async:      true,#}
                        data: {
                            search: request.term
                        },
                        success: function(data) {
                            response(data);
                        }
                    });
