fastadmin 自定义多级联动

index.html中添加一下代码

对应index.php控制器展示联动下拉内容

public function cxselect(){
	$id = $this->request->get('id');
	$pid              = $this->request->get('id');
	//处理对应的逻辑
    $where['status']  = array('eq','normal');
    $where['pid']     = array('in',$pid);
    $groupList = collection(SourceChannel::where($where)->field('id as value,name')->order('sort asc')->select())->toArray();
    
	$this->success('', null, $groupList);
}

对应index.js文件

{
     field: 'area', title: __('自定义'),titleTooltip:'自定义', searchList: function (column) {
      	 return Template('sourcetpl', {});
     }
}

联动数据展示成功后，再index.php控制器获取相应参数，处理表单逻辑。
