def scroll_by(delta_x, delta_y, device: nil)

Returns:
  • (Selenium::WebDriver::WheelActions) - A self reference.

Parameters:
  • delta_y (Integer) -- Distance along Y axis to scroll using the wheel. A negative value scrolls up.
  • delta_x (Integer) -- Distance along X axis to scroll using the wheel. A negative value scrolls left.

Other tags:
    Example: Scroll viewport by a specified amount - 
def scroll_by(delta_x, delta_y, device: nil)
  scroll(delta_x: delta_x, delta_y: delta_y, device: device)
end

def scroll_from(scroll_origin, delta_x, delta_y, device: nil)

Raises:
  • (Error::MoveTargetOutOfBoundsError) - If the origin with offset is outside the viewport.

Returns:
  • (Selenium::WebDriver::WheelActions) - A self reference.

Parameters:
  • delta_y (Integer) -- Distance along Y axis to scroll using the wheel. A negative value scrolls up.
  • delta_x (Integer) -- Distance along X axis to scroll using the wheel. A negative value scrolls left.
  • scroll_origin (ScrollOrigin) -- Where scroll originates (viewport or element center) plus provided offsets.

Other tags:
    Example: Scroll viewport by a specified amount with an offset -
    Example: Scroll from element by a specified amount with an offset -
    Example: Scroll from element by a specified amount -

end

def scroll_to(element, device: nil)

Returns:
  • (Selenium::WebDriver::WheelActions) - A self reference.

Parameters:
  • device (Object) -- Which device to use to scroll
  • element (Object) -- Which element to scroll into the viewport.

Other tags:
    Example: Scroll to element - 
def scroll_to(element, device: nil)
  scroll(origin: element, device: device)
