selenium除了使用firefox driver可使用chrome drvier、IE driver、Opera driver、android driver和ios driver(只用過chrome和Ie,其餘沒實踐過) 如下是官方給出的一個例子:android
from selenium import webdriver from selenium.common.exceptions 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.Firefox() # go to the google home page driver.get("http://www.google.com") # 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()ios
