获取错误在laravel中找不到控制器方法

I have a problem with routes in laravel. Do you have any idea? This is my code.

My jquery to send variable:

$('.del').click(function(event){
        event.preventDefault();
        if (confirm("Are you sure?")) {
            var id = $(this).attr('id');
            var actor = $('#actor').val();
            var url = "{{Asset('lesson/delete-chapter')}}";
            var url_dir ="{{Asset('lesson/view')}}"+actor;  //this just url to direct after del
            $.get(url,{id:id},function(data){   
                alert(data);
                $(location).attr("href",url_dir);
            });
        }
        return false;
});

This is my routes:

Route::get('lesson/delete-chapter','LessonController@postDeleteChapter');

This is my controller:

 public function postDeleteChapter(){
        $id = Input::get('id');

        $less = Lesson::where('chapter_id','=',$id);
        if(count($less)>0){
            $data['re'] = "Please delete lessons in this chapter!";
        }
        else{
            $chapter = Chapter::find($id);
            $less->delete();
            $data['re'] = "Deleted!";
        }
        echo json_decode($data);
    }

It's get error with routes delete, I dont know why, can you help me? Thanks you very much.

Use url function instead of asset.

$('.del').click(function(event){
        event.preventDefault();
        if (confirm("Are you sure?")) {
            var id = $(this).attr('id');
            var actor = $('#actor').val();
            var url = "{{url('lesson/delete-chapter')}}";
            var url_dir ="{{url('lesson/view')}}"+actor;  //this just url to direct after del
            $.get(url,{id:id},function(data){   
                alert(data);
                $(location).attr("href",url_dir);
            });
        }
        return false;
});
