Laravel 5.5 ajax success function returns empty array

Question

This question has been asked before but non of the solutions work for me. This my code

<meta name="csrf-token" content="{{csrf_token()}}">

and the script

<script type="text/javascript">
    $(document).ready(function () {
        $(".comment-rate-wrapper a img").on('click', function (e) {
            e.preventDefault();
            var item_id = 1;
            var url = "{{route('like.voteHandler', ':id')}}";
            url = url.replace(':id', item_id);
            //alert(url); I am sure thr url is correct and it outputs correctly
            $.ajaxSetup({
                headers: {
                    'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
                }
            });
            $.ajax({
                method: 'POST', // Type of response and matches what we said in the route
                url: url, // This is the url we gave in the route
                data: {
                    'item_id': item_id
                },
                success: function (result) { // What to do if we succeed
                    console.log(result);
                },
                error: function (jqXHR, textStatus, errorThrown) { // What to do if we fail
                    console.log(JSON.stringify(jqXHR));
                    console.log("AJAX error: " + textStatus + ' : ' + errorThrown);
                }
            });
        })
    })
</script>

and this is the controller function

    public function voteHandler($item_id)
    {
        echo "sas";
        return "hi";
    }

But it always returns an empty array and I have no idea why it is not working.

Thanks

try this = return response(['msg' => $message, 'status' => 'success']); — Jigs1212

@Jigs1212 I changed the controller function to both return result(['msg' => "hello", 'status' => 'success']); and return response(['msg' => "hello", 'status' => 'success']); but it doesn't work — M a m a D

Try this out in your controller

public function voteHandler(Request $request)
{
    return response()->json(["item_id" => $request->item_id]);
}

Edit: This was actually an error with the request method, change your route declaration to match your ajax request method POST

$router->post('{item_id}/voteHandler', 'LikeController@voteHandler')->name('like.voteHandler');

or change your ajax method to GET

I tried return response()->json(["item_id" => 12]); and the js success to success: function (response) { console.log(response);} still not working

Try to add dd($request); before the return to see if it reaches that function

When I visit the url in the browser directly, it outputs the dd result, but in ajax request it doesn't

This is route declaration $router->get('{item_id}/voteHandler', 'LikeController@voteHandler')->name('like.voteHandler');

If you can reach it by url it means it is a GETroute, change either the route or the method in your ajax post

You can check Your Ajax request like below way.You should try to below way.

public function voteHandler(Request $request) {
 if(Request::ajax()){
        return response()->json(['status'=>'Ajax request']);
    }
    return response()->json(['status'=>'Http request']);
}

Change the Parameter and print the inputs

public function voteHandler(Request $request)
{
    print_r($request->all());
}

Make sure it reaches this method. Use firebug to debug the same.
