Question

我正在根据文件中的分类例子,执行“平等倡议”。我愿向地主增加成果数目,而不是展示“成果(3)”。我知道,需要从这个例子中修改_____Menu的功能,但我对如何修改这一功能有疑虑。任何帮助我走上正确道路都将受到高度赞赏。

Here is the example code from jQuery UI Autocomplete Categories demo:

    <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", category: "" },
            { label: "antal", category: "" },
            { label: "annhhx10", category: "Products" },
            { label: "annk K12", category: "Products" },
            { label: "annttop C13", category: "Products" },
            { label: "anders andersson", category: "People" },
            { label: "andreas andersson", category: "People" },
            { label: "andreas johnson", category: "People" }
        ];

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



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

一个很好的战略是制造一个物品/现金,储存各类物品,作为与这一类价值相匹配的关键和系列物品。换言之,你们想要建设这样的东西:

{ "Products": ["annhhx10", "annk K12", /*etc*/],
  "People": ["anders andersson", "andreas andersson", /*etc*/]
}

一旦你建立,你就可以通过它来挖掘,并按其价值逐个产出。这样做的好处是,要获得项目数目,就必须花在与目前类别相对应的阵列中。类似:

$.widget("custom.catcomplete", $.ui.autocomplete, {
    _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, function (index, item) {
                self._renderItem(ul, item);
            });
        });
    }
});

$.widget("custom.catcomplete", $.ui.autocomplete, {
            _renderMenu: function (ul, items) {
                var self = this,
                currentCategory = "", itemCount = 0, itemsLength = items.length - 1;
                $.each(items, function (index, item) {
                    if (item.category != currentCategory) {
                        ul.find( .ui-autocomplete-category:last ).text(function () { return $(this).text() +     + itemCount });
                        ul.append("<li class= ui-autocomplete-category >" + item.category + "</li>");
                        currentCategory = item.category;
                        itemCount = 1;
                    }
                    else {
                        itemCount++;
                    }

                    if (index === itemsLength) {
                        ul.find( .ui-autocomplete-category:last ).text(function () { return $(this).text() +     + itemCount });
                    }

                    self._renderItem(ul, item);
                });
            }
        });
