Laravel 5 how to get controller display simple message box or alert?

Question

Cannot find solution to this simple problem, i just do some voting app, and if users votes I would like to show simple alert like "Thanks" , but I cannot find the way to do it from the controller? I have tried the simple jQuery code like this but it's not working.

echo "<script>alert('You have already voted');</script>";

Any simple solutions?

public function voting()
{
    $ip=$_SERVER['REMOTE_ADDR'];
    $id = Input::get('msg_id');
    $vote = Input::get('vote');
    $count = Voting::wheremes_id_fk($id)->whereip_add($ip)->count();

    if($count==0)
    {
        if($vote == "up")
        {
            Project::whereid($id)->increment('up');

            Voting::insert(
                array('mes_id_fk' => $id, 'ip_add' => $ip )
            );
        }
        else if ($vote=="down") {

            Project::whereid($id)->decrement('down');

            Voting::insert(
                array('mes_id_fk' => $id, 'ip_add' => $ip )
            );
        }
    } 
    else {
        // How to popup "thanks" alert??
    }
}

If you are using ajax to do the vote, return a json response and use JavaScript to respond to the json response.

example:

public function vote()
{
  //your voting code
  return Response::json(['success'=>true]);
}

and in your JavaScript, check the json

$.post('/vote/', { id: 123   }, function(data){
    if(data.success== true)
    {
      alert('Thanks for voting);
    }
}

If you are not using ajax, simply use the Session flash.

i.e., from your controller,

public function vote()
{
  //your voting code
  Session::flash('msg', 'Thanks for voting');
 return Redirect::back();
}

and from View,

@if(Session::has('msg'))
  {{Session::get('msg')}}
@endif
