python - Selenium / Python：使用键盘输入

Question

问题：无法选择元素，然后执行向下箭头的键盘输入。

情况：我正在打开一个页面，进行了一些选择，并且在每个选择都由 .click() 事件执行后，我想模拟向下箭头的键盘输入。我收到异常错误，并尝试了不同的方法，但没有成功。

错误：WebDriverException: Message: u'unknown error: cannot focus element\n (Session info: chrome=30.0.1599.69)\n (Driver info: chromedriver=2.3,platform=Mac OS X 10.8.4 x86_64)'

def test_00_validation_test(self):
        driver = self.driver
        driver.set_window_position(0,0)
        driver.maximize_window()
        driver.get(self.base_url)
        driver.find_element_by_id("open").click()
        driver.find_element_by_id("screen_name").send_keys("user")
        driver.find_element_by_id("password").send_keys("pwd")
        driver.find_element_by_id("login_submit").click()
        driver.find_element_by_id("card5").click()
        driver.find_element_by_id("make_picks").click()
        driver.find_element_by_id("team3").click()
        driver.find_element_by_id("team3").send_keys("\25")
        driver.find_element_by_id("team2").click()
        driver.find_element_by_id("team2").send_keys("\25")
        driver.find_element_by_id("submit_picks").click()
        self.assertEqual("Picks Saved", self.close_alert_and_get_its_text())

Answer 1

 switch_to_alert()
    Switches focus to an alert on the page.

文档

您必须专注于open_popup在该弹出窗口中发送密钥

Answer 2

找到了一个可行的解决方案。使用driver.execute_script("window.scrollTo(0,0);")
