chào các bạn dưới đây là class tạo button cố định, giờ mình muốn truyền giá trị theo ý mình như borderRadius=số mình gõ vào, size kích thước button mình cũng gõ số vào. mỗi lần thay đổi giá trị nhập vào button cũng thay đổi theo giá trị đó mà mình không biết khai báo để truyền giá trị vào chỗ nào các bạn hướng dẫn mình với:
