Send data to controller using AJAX

I am new to Ajax and I am using laravel, now i want to have a delete button that will send the id of the item that i want to delete to controller. Here is my code.

Views

      <div class="row">
        @foreach($photos as $photo)
     <div class="col-xs-3 col-md-1">
    <button onclick="removeItem({{$photo->id}}); return false;">Delete</button>   
          </div> 
          @endforeach

        </div>

Here is my script

     <script type="text/javascript">
    function removeItem($myvar) {
  $.ajax({
 type : "POST",
url : "deletephoto",
 );}

   }
    </script>

I want to send this to this route

       Route::post('deletephoto','GamefarmsController@deletephoto');

on my Controller I want to do this just to test if its working

public function deletephoto()
{
    dd($myvar);
}
