dcatadmin批量操作时异步请求获取当前选中的id

需求

批量发货时，需要可以修改每个发货单中的收货地址,所以需要点击批量生成后生成一个表单，并获取到选取的ids

遇到的问题

加载form时无法获取ids

解决方法

1. 重写Modal类
   GridBatchModal.php

namespace App\Admin\Actions;

use Dcat\Admin\Widgets\Modal;

class GridBatchModal extends Modal
{
    protected function getRenderableScript() {
        if (!$this->getRenderable()) {
            return;
        }

        $url = $this->renderable->getUrl();

        return <<<JS


target.on('{$this->target}:load', function () {

    var key = Dcat.grid.selected('')

    Dcat.helpers.asyncRender('{$url}&ids='+key, function (html) {
        body.html(html);

        {$this->loadScript}

        target.trigger('{$this->target}:loaded');
    });
});
JS;
    }
}

2. 使用modal
   CommonGridBatchAction.php

namespace App\Admin\Actions\Grid;

use App\Admin\Actions\GridBatchModal;
use App\Admin\Forms\BatchSureSendForm;
use Dcat\Admin\Grid\BatchAction;


class CommonGridBatchAction extends BatchAction
{

    /**
     * @return string
     */
	protected $title = 'Title';
    protected $function;
    public function __construct($title = null,$function = null)
    {
        $this->title = $title;
        $this->function = $function;

    }

    public function render()
    {

        $function = $this->function;
        return $this->$function();
    }

    public function batch_erp_out_order_send(){

        $keys = $this->getKey();
        $form = BatchSureSendForm::make()->payload([ ]);
        $modal = GridBatchModal::make()
            ->xl()
            ->title($this->title)
            ->body($form)
            ->button($this->title);

        return $modal;
    }

}

3. 使用Form
   BatchSureSendForm.php

namespace App\Admin\Forms;

use App\Models\ExpressOrder;
use Dcat\Admin\Contracts\LazyRenderable;
use Dcat\Admin\Traits\LazyWidget;
use Dcat\Admin\Widgets\Form;
use Illuminate\Support\Facades\DB;

class BatchSureSendForm extends Form implements LazyRenderable
{
    use LazyWidget;
    /**
     * Handle the form request.
     *
     * @param array $input
     *
     * @return mixed
     */
    public function handle(array $input)
    {
  
        DB::beginTransaction();
     	//发货流程
        if($res == true){
            DB::commit();
            return $this
                ->response()
                ->success('发货成功')
                ->refresh();
        }else{
            DB::rollBack();
            return $this
                ->response()
                ->error($msg);
        }

    }

    /**
     * Build a form here.
     */
    public function form()
    {
    	//或者$this->payload['ids']
        dump(request('ids'));
    }
