六、第一个webdriver示例

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.Chrome()

# 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()
