FastAdmin表格添加统计信息

如上图，在列表顶部添加订单统计信息，统计符合当前筛选条件的记录。

列表页html中：

    <div class="panel-body">
        <div id="myTabContent" class="tab-content">
            <div class="tab-pane fade active in" id="one">
                <div class="widget-body no-padding">
                    <div id="toolbar" class="toolbar">
                        <a href="javascript:;" class="btn btn-primary btn-refresh" title="{:__('Refresh')}" ><i class="fa fa-refresh">i> a>
 
                    
                        <a href="javascript:;" class="btn btn-default" style="font-size:14px;color:dodgerblue;">
                            <span class="extend">
                                订单金额: <span id="price">0span> 订金金额: <span id="dingjin_price">0span> 订单数量: <span id="count">0span>
                            span>
                        a>
                    
                    div>
                    <table id="table" class="table table-striped table-bordered table-hover table-nowrap"
                           data-operate-edit="{:$auth->check('order/edit')}"
                           data-operate-del="{:$auth->check('order/del')}"
                           width="100%">
                    table>
                div>
            div>
 
        div>
    div>
div>

对应的js文件，index方法最后：

            table.on('load-success.bs.table', function (e, data){
                    $("#price").text(data.extend.price);
                    $("#dingjin_price").text(data.extend.dingjin_price);
                    $("#count").text(data.extend.count);
            });
            // 为表格绑定事件
            Table.api.bindevent(table);

php控制器

            $price = $this->model
                ->with(['user'])
                ->where($where)
                ->sum('price');
            $dingjin_price = $this->model
                ->with(['user'])
                ->where($where)
                ->sum('dingjin_price');
            $count = $this->model
                ->with(['user'])
                ->where($where)
                ->count();
            $result = array("total" => $list->total(), "rows" => $list->items(),"extend" => compact(  'price', 'dingjin_price','count'));
