for x, y in param:
                center_x = int(x) - div_size['width'] / 2
                center_y = int(y) - div_size['height'] / 2
                logging.info("click at (%.2f, %.2f)" % (center_x, center_y))
                action_chains.move_to_element_with_offset(element, center_x,
center_y).click().perform()
                time.sleep(random.randint(0, 10) / 10)

按文档说move_to_element_with_offset是Move the mouse by an offset of the
specified element. Offsets are relative to the top-left corner of the element.

但是我这里必须以element中心为原点才能成功呢？
