另一方面，使用操作通道如果需要场景一致的操作，则需要操作通道模块。
二、动作通道的使用方法和原理分析动作通道可用于模拟一系列的鼠标操作、鼠标移动、鼠标按钮操作、按钮操作、上下文操作； 鼠标点击、双击、右击、拖动等。
官方网站使用示例：
# actionchainscanbeusedinachainpattern :链式标记menu=driver.find _ element _ by _ CSS _ selector (.nav ' ) )。 hidden _ submenu=driver.find _ element _ by _ CSS _ selector (.nav # submenu1' ) actionchains (驱动器).move or ara then performed.分步书写方法menu=driver.find _ element _ by _ CSS _ selector (.nav ' ) hidden _ su submenu=drremend to_element ) menu ) actions.click(hidden_submenu ) actions.Perrions ) )。操作进入self._actions (类型为list )队列，返回self实例本身，并使用perform方法依次执行3358www.Sina.com/的操作因此，可以继续单击类中的其他操作方法来配置chains，并在perform ()中依次运行。
