六、第一个webdriver示例
- from selenium import webdriver
- from <span style="box-sizing: inherit;">selenium.common.exceptions</span> import TimeoutException
- from selenium.webdriver.support.ui import WebDriverWait # available since 2.4.0
- from selenium.webdriver.support import expected_conditions as EC # available since 2.26.0
- # Create a new instance of the Firefox driver
- driver = webdriver.Chrome()
- # go to the google home page
- 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>
- # the page is ajaxy so the title is originally this:
- print driver.title
- # find the element that's name attribute is q (the google search box)
- inputElement = driver.find_element_by_name("q")
- # type in the search
- inputElement.send_keys("cheese!")
- # submit the form (although google automatically searches now without submitting)
- inputElement.submit()
- try:
- # we have to wait for the page to refresh, the last thing that seems to be updated is the title
- WebDriverWait(driver, 10).until(EC.title_contains("cheese!"))
- # You should see "cheese! - Google Search"
- print driver.title
- finally:
- driver.quit()
