from selenium import webdriverfrom selenium.webdriver.common.by import Byfrom selenium.webdriver.support.ui import WebDriverWaitfrom selenium.webdriver.support import expected_conditions as EC
driver = webdriver.Chrome()driver.get("http://somedomain/url_that_delays_loading")try:    element = WebDriverWait(driver, 10).until(        EC.presence_of_element_located((By.ID, "myDynamicElement"))    )finally:    driver.quit()

from selenium import webdriver
driver = webdriver.Chrome()driver.implicitly_wait(10) # secondsdriver.get("http://somedomain/url_that_delays_loading")myDynamicElement = driver.find_element_by_id("myDynamicElement")

方法1: 获取后循环  element = driver.find_element_by_xpath("//select[@name='name']")  all_options = element.find_elements_by_tag_name("option")  for option in all_options:    print("Value is: %s" % option.get_attribute("value"))    option.click()

方法2: Select直接选择  from selenium.webdriver.support.ui import Select  select = Select(driver.find_element_by_name('name'))  select.select_by_index(index)  select.select_by_visible_text("text")  select.select_by_value(value)

取消：select = Select(driver.find_element_by_id('id'))select.deselect_all()

driver.find_element_by_id("submit").click()

您可以使用拖放，无论是移动一个元素，或放到另一个元素内:  element = driver.find_element_by_name("source")  target = driver.find_element_by_name("target")
  from selenium.webdriver import ActionChains  action_chains = ActionChains(driver)  action_chains.drag_and_drop(element, target).perform()

<a href="somewhere.html" target="windowName">Click here to open a new window</a>

web应用来说，没有任何frames或者只包含一个window窗口是比较罕见的。 WebDriver 支持在不同的窗口之间移动，只需要调用``switch_to_window``方法即可:
driver.switch_to_window("windowName")

Selenium WebDriver 内置了对处理弹出对话框的支持。 在你的某些动作之后可能会触发弹出对话框，你可以像下面这样访问对话框:
alert = driver.switch_to_alert()

driver.get("http://www.example.com")driver.forward()driver.back()

打开一个页面 driver.get(“http://www.example.com”)
现在设置Cookies，这个cookie在域名根目录下（”/”）生效 cookie = {‘name’ : ‘foo’, ‘value’ : ‘bar’} driver.add_cookie(cookie)
现在获取所有当前URL下可获得的Cookies driver.get_cookies()
