What's going on when undefined appears? Please help.

Question

Answer 1

The user's real-name information filled in is the only proof for prize redemption. If the real-name information filled in is incorrect due to personal reasons and the prize cannot be redeemed, all losses will be borne by the user.

Answer 2

Mine is the same. Later I found that the teacher’s data.message was written incorrectly in the ajax at the front desk. It should be data.result. After I changed this, it became normal.

Answer 3

It should be that the js code variable is not defined

Answer 4

public function checkLogin(Request $request)

{

//Initial return parameters

$status =0;

$result =' ';

          $data = $request ->param();

##                                                     use using ‐                   through using ’’s ’ through     ‐     ‐ ‐ ‐ // $rule =[

                                                                                                >'require|captcha',

// ];

// //Verify

// $result = $this->validate($data,$rule);

return ['status'=>$status,'message'=>$result,'data'=>$data];

}
