我想选择自动完成框项目列表。但它不工作。我已经编写了这段代码来获取该项目。每当我使用 self._renderItemData = function (ul, item)此功能自定义方式选择停止时，当我评论此功能时，我的代码工作正常。请帮助我知道我错在哪里。我使用 jquery ui 1.9 来编写代码。

$(document).ready(function () {
    var term = "";
    var type = "";
    var key = "";
    $("#searchTextBox").autocomplete({
        minLength: 2,
        autoFocus: true,
        source: function (request, response) {
            $.ajax({
                url: "../CustomHandlers/SearchHandler.ashx",
                dataType: "json",
                contentType: 'application/json; charset=utf-8',
                data: { term: request.term },
                success: function (data) {
                    if (!data || data.length == 0) {
                        response([{
                            label: "noMatched",                               
                            hcount:0,
                            type: "noResult",
                            key: "noResult"                             
                        }]);                            
                    }
                    else {
                        response($.map(data, function(item) {
                            return {
                                label: item.label,                                   
                                hcount:item.record,
                                type: item.type,
                                key: item.key
                            }
                        }))
                    }                    
                }                   
            });

            $.ui.autocomplete.prototype._renderMenu=function (ul, items) {
                var self = this;
                currentType = "";
                $.each(items, function (index, item) {
                    if (item.type != currentType) {
                        ul.append("<li class='ui-autocomplete-type'>" + item.type + "</li>");
                        currentType = item.type;
                    }

                    self._renderItemData(ul, item);

                });
                self._renderItemData = function (ul, item) {
                    var searchhtml = "<a class='autocomplitList'>" + item.label + "<span>" + "(" + item.hcount + ") " + "</span>" + "</a>";
                    return $("<li></li>")
                            .data("item.autocomplete", item)
                            .append(searchhtml)
                            .appendTo(ul);
                };
            }

        }

        , select: function (event, ui)

试试这个

$(document).ready(function() {

    var type = "";
    var key = "";

    $.ui.autocomplete.prototype._renderMenu = function(ul, items) {
