jQuery UI使用计数机制自动完成类别

我正在基于文档中的类别示例实现jQuery UI自动完成.我想将结果数添加到Categories标题中,因此不显示“Products”而是显示“Products(3)”.我知道_renderMenu函数需要从示例中修改,但我无法理解如何修改它.任何帮助我开始正确的道路将非常感激.

以下是jQuery UI Autocomplete Categories演示的示例代码：

<script>
    $.widget( "custom.catcomplete",$.ui.autocomplete,{
        _renderMenu: function( ul,items ) {
            var self = this,currentCategory = "";
            $.each( items,function( index,item ) {
                if ( item.category != currentCategory ) {
                    ul.append( "<li class='ui-autocomplete-category'>" + item.category + "</li>" );
                    currentCategory = item.category;
                }
                self._renderItem( ul,item );
            });
        }
    });
    </script>
    <script>
    $(function() {
        var data = [
            { label: "anders",category: "" },{ label: "andreas",{ label: "antal",{ label: "Annhhx10",category: "Products" },{ label: "Annk K12",{ label: "Annttop C13",{ label: "anders ande@L_489_9@on",category: "People" },{ label: "andreas ande@L_489_9@on",{ label: "andreas johnson",category: "People" }
        ];

        $( "#search" ).catcomplete({
            delay: 0,source: data
        });
    });
    </script>



<div class="demo">
    <label for="search">Search: </label>
    <input id="search" />
</div>

{ "Products": ["Annhhx10","Annk K12",/*etc*/],"People": ["anders ande@L_489_9@on","andreas ande@L_489_9@on",/*etc*/]
}

$.widget("custom.catcomplete",{
    _renderMenu: function(ul,items) {
        var self = this,categories = { };

        /* Build a Dictionary/hash where keys are categories and values are 
         * arrays of items with that category 
         */
        $.each(items,function (index,item) {
            if (!categories.hasOwnProperty(item.category)) {
                 categories[item.category] = [item];
            } else {
                categories[item.category].push(item);
            }
        });

        /* Iterate over the hash we just built and display a category followed by its
         * items.
         */
        $.each(categories,function(category,items) {
            if (category) {
                ul.append("<li class='ui-autocomplete-category'>" + category + " (" + items.length + ")</li>");
            }
            $.each(items,item) {
                self._renderItem(ul,item);
            });
        });
    }
});
