Fastadmin的搜索下拉列表框动态

 {field: 'lablegroup.id', title:'栏目ID',visible: false, searchList:$.getJSON('lable/group/source')},

后端代码如下

public function source(){
        // $json = cache('source');
        $json =false;
        if ($json===false){
            $list = $this->model->select();
            foreach ($list as $key=>$val){
                $val['name'] = $val['name'].'---'. $val['remark'];   
            }
            $json = json($list);
            // cache('source',$json);
        }
        return $json;
    }
