【ActionChains方法列表】:

move_to_element(to_element)     ——鼠标移动到某个元素
click(on_element=None)          ——单击鼠标左键
click_and_hold(on_element=None) ——点击鼠标左键，不松开
double_click(on_element=None)   ——双击鼠标左键
context_click(on_element=None)  ——点击鼠标右键

drag_and_drop(source, target)                               ——拖拽到某个元素然后松开
drag_and_drop_by_offset(source, xoffset, yoffset)           ——拖拽到某个坐标然后松开
move_by_offset(xoffset, yoffset)                            ——鼠标从当前位置移动到某个坐标
move_to_element_with_offset(to_element, xoffset, yoffset)   ——移动到距某个元素（左上角坐标）多少距离的位置

key_down(value, element=None)                ——按下某个键盘上的键
key_up(value, element=None)                  ——松开某个键
send_keys_to_element(element, *keys_to_send) ——发送某个键到指定元素
send_keys(*keys_to_send)                     ——发送某个键到当前焦点的元素
