selenium python中的send（）函数不起作用

所有程序运行正常，但“ActionChains（driver）、key_down（Keys.ALT）、send_Keys（F”、“A”）、key_up（Keys.ALT）、send_Keys（Keys.HOME）”不工作。如何解决

我刚加入selenium python。请指导我

您需要在末尾添加

.perform（）

        Final_Path = suni + str(t_row) + ashu + pansing
        driver.find_element_by_xpath(Final_Path).click()
        handles = driver.window_handles
        size = len(handles)

            ActionChains(driver).key_down(Keys.ALT).send_keys("F", "A").key_up(Keys.ALT).send_keys(Keys.HOME)
            driver.close()
        driver.switch_to.window(parent_handle)

从文件中：

在ActionChains对象上调用动作的方法时，动作存储在ActionChains对象的队列中。调用perform（）时，将按照事件排队的顺序触发事件

动作链（驱动程序）。键向下（Keys.ALT）。发送键（“F”）。发送键（“A”）。键向上（Keys.ALT）。发送键（Keys.HOME）。执行（）但不工作哪种类型的问题浏览器或其他类型。请解决我的问题

ActionChains(driver).key_down(Keys.ALT).send_keys("F", "A").key_up(Keys.ALT).send_keys(Keys.HOME).perform()
