这是我关注http://selenium-python.readthedocs.io/waits.html
的文档抛出异常:
driver = webdriver.Chrome(CHROME_DRIVER_PATH)
iframe_xpath = "//*[@id='targetForCaptcha1']/div/div/iframe"
captcha_iframe = driver.find_element_by_xpath(iframe_xpath)
driver.switch_to_frame(captcha_iframe)
checkBox = WebDriverWait(driver, 10).until(EC.presence_of_element_located((By.XPATH, iframe_xpath)))
checkBox.click()
raise TimeoutException(message, screen, stacktrace) selenium.common.exceptions.TimeoutException: Message:
然而这有效:
driver = webdriver.Chrome(CHROME_DRIVER_PATH)
iframe_xpath = "//*[@id='targetForCaptcha1']/div/div/iframe"
captcha_iframe = driver.find_element_by_xpath(iframe_xpath)
action=ActionChains(driver)
action.move_to_element(captcha_iframe)
action.click().perform()
以上两个是从头开始运行python脚本的独立会话。
为什么以前的工作似乎不是更标准的做法呢?
答案 0 :(得分:1)
iframe是主DOM的节点。致电driver.switch_to_frame(captcha_iframe)
后,您切换到了iframe&#39; <{1}}所在的DOM和节点不再可访问。
因此,如果要跳过By.XPATH, iframe_xpath
行
