排序箭头，升序，降序简单实现

css不好实现的效果，通过背景图片来弥补。

css

    <style>
        .sortedASC{
            background: url({sh::PUB}img/icon-table-sort-asc.png) no-repeat 80% 5px #eee;
        }
        .sorted
        {
            background: url({sh::PUB}img/icon-table-sort.png) no-repeat 80% 9px #eee ;
        }

        .sortedDESC{
            background: url({sh::PUB}img/icon-table-sort-desc.png) no-repeat 80% 11px #eee;
        }
    </style>

html

            <tr role="row">
                <th role="columnheader" tabindex="0" aria-controls="sample-table-2" rowspan="1" colspan="1" aria-label="Domain: activate to sort column ascending">默认</th>
                <th class="sort sortedASC" role="columnheader" tabindex="0" aria-controls="sample-table-2" rowspan="1" colspan="1" aria-label="Price: activate to sort column ascending">销量</th>
                <th class="sort sortedDESC" role="columnheader" tabindex="0" aria-controls="sample-table-2" rowspan="1" colspan="1" aria-label="Price: activate to sort column ascending">新品</th>
                <th class="sort sorted" role="columnheader" tabindex="0" aria-controls="sample-table-2" rowspan="1" colspan="1" aria-label="Update: activate to sort column ascending">
                    <i class="ace-icon fa fa-clock-o bigger-110 hidden-480"></i> 价格
                </th>
            </tr>

效果有了，剩下的就是通过js逻辑和程序逻辑来实现排序了。

实现功能

html改造

<th class="sort" data-type="default" role="columnheader" tabindex="0" aria-controls="sample-table-2" rowspan="1" colspan="1" aria-label="Domain: activate to sort column ascending">默认</th>
<th class="sort <if condition='$sale eq 1'>sortedASC<elseif condition='$sale eq -1'/>sortedDESC<else />sorted</if>" data-type="sale" role="columnheader" tabindex="0" aria-controls="sample-table-2" rowspan="1" colspan="1" aria-label="Price: activate to sort column ascending">销量</th>
<th class="sort <if condition='$new eq 1'>sortedASC<elseif condition='$new eq -1'/>sortedDESC<else />sorted</if>" data-type="new" role="columnheader" tabindex="0" aria-controls="sample-table-2" rowspan="1" colspan="1" aria-label="Price: activate to sort column ascending">新品</th>
<th class="sort <if condition='$price eq 1'>sortedASC<elseif condition='$price eq -1'/>sortedDESC<else />sorted</if>" data-type="price" role="columnheader" tabindex="0" aria-controls="sample-table-2" rowspan="1" colspan="1" aria-label="Update: activate to sort column ascending">
    <i class="ace-icon fa fa-clock-o bigger-110 hidden-480"></i> 价格
</th>

增加date-type，统一的class 'sort'。

js事件

$('.sort').click(function() {
    var type = $(this).data('type');
    var category_id = '{sh:$category_id}';
    var sort;
    if ($(this).hasClass('sorted')) { // 降序
        $(this).removeClass('sorted').addClass('sortedDESC');
        sort = '-1';
    }else if ($(this).hasClass('sortedASC')) { // 降序
        $(this).removeClass('sortedASC').addClass('sortedDESC');
        sort = '-1';
    }else if ($(this).hasClass('sortedDESC')) { // 升序
        $(this).removeClass('sortedDESC').addClass('sortedASC');
        sort = '1';
    }
    if (type =='default') {
        location.href="{sh::U('Store/Home/goodslist',array('category_id'=>'"+category_id+"'))}";
    } else {
        location.href="{sh::U('Store/Home/goodslist',array('category_id'=>'"+category_id+"','"+type+"'=>'"+sort+"'))}";
    }

    
});

后台处理

if ($sale = $this->_request('sale')) {
    if ($sale == '-1') {
        $order = '(salecount+fakemembercount) desc';
    }

    if ($sale == '1') {
        $order = '(salecount+fakemembercount) asc';
    }
    $this->assign('sale',$sale);
}

if ($price = $this->_request('price')) {
    if ($price == '-1') {
        $order = 'oprice desc';
    }

    if ($price == '1') {
        $order = 'oprice asc';
    }
    $this->assign('price',$price);
}

if ($new = $this->_request('new')) {
    if ($new == '-1') {
        $order = 'addtime desc';
    }

    if ($new == '1') {
        $order = 'addtime asc';
    }
    $this->assign('new',$new);
}

tips:这里是大概的思路，具体需要你们根据实际情况去实现，可以优化成异步加载。
