六、第一个webdriver示例

1. from selenium import webdriver
   
2. from <span style="box-sizing: inherit;">selenium.common.exceptions</span> import TimeoutException
   
3. from selenium.webdriver.support.ui import WebDriverWait # available since 2.4.0
   
4. from selenium.webdriver.support import expected_conditions as EC # available since 2.26.0
   
5. # Create a new instance of the Firefox driver
   
6. driver = webdriver.Chrome()
   
7. # go to the google home page
   
8. driv<span style="color: rgb(47, 79, 79);">er.get("</span><span style="color: rgb(47, 79, 79); box-sizing: inherit;">http://www.google.com</span><span style="color: rgb(47, 79, 79);">")</span>
   
9. # the page is ajaxy so the title is originally this:
   
10. print driver.title
    
11. # find the element that's name attribute is q (the google search box)
    
12. inputElement = driver.find_element_by_name("q")
    
13. # type in the search
    
14. inputElement.send_keys("cheese!")
    
15. # submit the form (although google automatically searches now without submitting)
    
16. inputElement.submit()
    
17. try:
    
18. # we have to wait for the page to refresh, the last thing that seems to be updated is the title
    
19. WebDriverWait(driver, 10).until(EC.title_contains("cheese!"))
    
20. # You should see "cheese! - Google Search"
    
21. print driver.title
    
22. finally:
    
23. driver.quit()
