配合 AJAX

$(document).ready(function() {

    $("#select").autocomplete({
        source: function(req, add) {
                var v=$('#select');
                if(v.val().length){
                $.ajax({
                url: 'ajax/select_ajax.php',
                data: {'v':v.val()},
                type:"POST",
                dataType:'json', // PHP傳JSON問題，請參考"AJAX JSON 空白"篇

                success: function(msg){
                    var list = [];
                    $.each(msg, function(i, val) {
                        list.push({
                            label: val['name'],
                            txt: val['id']
                        });
                    });
                    add(list);
                },
            });
            }
        },
        select: function(event, list) {
            $('#txt').val(list.item.txt);
        }
    });
});
