通过ajax返回存储过程输出

Question

我目前有一个工作流程，在我的刀片中进行 ajax 调用，该调用通过控制器进行调用，并且该函数使用 PDO 命中存储过程调用。此调用成功，我的存储过程正确执行/插入，并设置为返回我的输出。我现在唯一的问题是：

如何获取存储过程的输出并将其传递回刀片以获取隐藏输入？没有页面刷新，所以当 AJAX 调用成功时，我想将服务文件的输出放入刀片中的隐藏输入中。我怎样才能正确地做到这一点？

刀片：

$.ajax({

   type:'POST',
   url:'campaigns/createCampaign',
   data:{campaignName:campaignName, attribute:attribute},
    _token: '{{ csrf_token() }}',
   success:function(data){
        intro_modal.hide();
   }
});

控制器：

public function createCampaign(Request $request)
{
    $campaignName = $request->campaignName;
    $attribute = $request->attribute;

    $campaignService = new CampaignService();
    $createCampaign = $campaignService->createCampaign($campaignName, (int) $attribute);

    //return response()->$campaignService;
}

服务：

function createCampaign($campaignName, $attribute){

    $stmt = \DB::connection('odbc')->getPdo()->prepare('CALL PROCEDURES.INSERT_CAMPAIGN(?,?,?)');

    $stmt->bindValue(1,$campaignName, PDO::PARAM_STR);
    $stmt->bindValue(2,$attribute, $attribute==0 ? PDO::PARAM_NULL : PDO::PARAM_INT);
    $stmt->bindParam(3,$out2, PDO::PARAM_INT);

    $stmt->execute();

}

Answer 1

在你的createCampaign

function createCampaign($campaignName, $attribute){

    $stmt = \DB::connection('odbc')->getPdo()->prepare('CALL PROCEDURES.INSERT_CAMPAIGN(?,?,?)');

    $stmt->bindValue(1,$campaignName, PDO::PARAM_STR);
    $stmt->bindValue(2,$attribute, $attribute==0 ? PDO::PARAM_NULL : PDO::PARAM_INT);
    $stmt->bindParam(3,$out2, PDO::PARAM_INT);
    $stmt->execute();

    return $out2;
}

在您的控制器

中

使用这些类：

use Illuminate\Support\Facades\Response;
use Illuminate\Http\Response as HttpResponse;

返回 JSON 响应：

public function createCampaign(Request $request)
{
    $campaignName = $request->campaignName;
    $attribute = $request->attribute;

    $campaignService = new CampaignService();
    $createdCampaignId = $campaignService->createCampaign($campaignName, (int) $attribute);

    return Response::json(["campaign_id" => $createdCampaignId)
            ->setStatusCode(HttpResponse::HTTP_OK);
}

在您的 Blade 模板中

$.ajax({

   type:'POST',
   url:'campaigns/createCampaign',
   data:{campaignName:campaignName, attribute:attribute},
    _token: '{{ csrf_token() }}',
   success:function(data){
        intro_modal.hide();
       // data.campaign_id will contains the new campain id
   }
});

之后，您只需将data.campaign_id 的值插入jQuery 即可。
