提交后，您可以通过重定向

you can redirect after submission by doing this

return redirect()->to('career/confirmation/'.$id); //pass your dynamic id

或通过这样做

return redirect()->route('confirmationMsg',['id'=>$id]); //pass your dynamic id

这样做，$id = $applicant->id;

替换此行

return redirect(route('confirmationMsg'));与此

return redirect()->route('confirmationMsg',['id'=>$id]); //pass your dynamic id
