<script type="text/javascript">

$('.remove_button').click(function(event) {
    event.preventDefault();
    var myurl = $(this).attr('href');
    var jqxhr = $.ajax({
     url:myurl,
     type:'POST',
    }).done(function() {
      var response = JSON.parse(jqxhr.responseText);
      var element = $("[cid='"+(response.cat_id)+"']");
      $(element).removeClass('cat_sec');

    }).fail(function() {
      alert("Failure! "+jqxhr.responseText);
    });
  });



</script>
@stop

and for controller,

public function ajax_remove_cat(Request $request, $inf_id, $cat_id) {
    $user = Auth::user();
    $agent = $user->getTypeModel();
    $influencer = $this->influencer->findBYId($inf_id);

    DB::table('categories_influencers')->where('categories_id', $cat_id)->delete();

    if($request->ajax()) {

        return response()->json(array('responsecode'=>'1','action'=>'delete','cat_id'=>$request->route('cat_id')));
 }

}

i am newbie to laravel, really have no idea where is the problem is , please help me get through this.

The reason you get 500 Error is that by default Laravel uses its HTTP Middleware to protect against CSRF attacks. You need to include a _token containing your csrf_token() value. Don't just resort to get if it is better to use post. For example, what happens if you actually navigate to that route?
