Selenium + Python Warning box handling

This is a few days of learning Webdriver's warning box, specifically using the Switch_to_alert () method to navigate to Alert/confirm/prompt and then using Text/accept/dismiss/send_ Keys and other methods to operate.

But has been stuck in the acceptance warning box This step, in the book is given an example of Baidu homepage Search Settings pop-up window, but after the code runs, always in error:selenium.common.exceptions.NoSuchElementException: Message:unable to locate element: Search settings ("Search Settings" here may be other targeting information). Later think, can Baidu home has something changed, I try to do the same on the search page, the results can be!

Attached code:

From selenium import Webdriver

From Selenium.webdriver.common.action_chains import Actionchains

Import time

Driver = Webdriver. Firefox ()

Driver.implicitly_wait (10)

Driver.get ("http://www.baidu.com")

driver.find_element_by_id ("kw"). Send_keys ("Selenium")

driver.find_element_by_id ("su"). Click ()

#鼠标悬停至 "Settings" link

#setting = Driver.find_element_by_css_selector ('. PF ')

setting = Driver.find_element_by_link_text ("Settings")

Actionchains (Driver). Move_to_element (setting). Perform ()

#打开搜索设置

Driver.find_element_by_link_text ("Search Settings"). Click ()

#driver. Find_element_by_class_name ("Setpref"). Click ()

Time.sleep (2)

# Save Settings

Driver.find_element_by_class_name (' Prefpanelgo '). Click ()

Time.sleep (2)

#接受警告框

Driver.switch_to_alert (). Accept ()

Driver.quit ()
