from selenium import webdriver
from selenium.webdriver.common.keys import Keys
# 找一個節點
element = driver.find_element_by_id("passwd-id")
element = driver.find_element_by_name("passwd")
element = driver.find_element_by_xpath("//input[@id='passwd-id']")
# 輸入，清除,點擊
element.send_keys()
element.clear()
element.click()
# 拖放
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()
# cookie
driver.get("http://example.com")
cookie = {'name':'foo','value':'bar'}
driver.add_cookie(cookie)
driver.get_cookies()

元素定位

from selenium.webdriver.common.by import By

driver.find_element(By.XPATH,'//button[text()="Some Text"]')
driver.find_elements(By.XPATH,'//button')
# 屬性
ID = "id"
XPATH = "xpath"
LINK_TEXT = "link text"
PARTIAL_LINK_TEXT = "partial link text"
NAME = "name"
TAG_NAME = "tag_name"
CLASS_NAME = "class name"
CSS_SELECTOR = "css selector"

wait

顯示

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC

driver = webdriver.Firefox()
driver.get("http://somedomain/url_that_delay_loading")
try:
    element = WebDriverWait(driver,10).until(
        EC.presence_of_element_located((By.ID,"myDynamicElement"))
    )
finally:
    driver.quit()

隱式

from selenium import webdriver

driver = webdriver.Firefox()
driver.implicitly_wait(10) # seconds
driver.get("http://somedomain/url_that_delays_loading")
myDynamicElement = driver.find_element_by_id('myDynamicElement')

行爲

當你在ActionChains對象上調用行爲方法時，這些行爲會存儲在ActionChains對象的一個隊列裏。調用perform()時，這些動作就以他們隊列的順序來觸發

menu = driver.find_element_by_css_selector(".nav")
hidden_submenu = driver.find_element_by_css_selector(".nav #submenu1")

actions = ActionChains(driver)
actions.move_to_element(menu)
actions.click(hidden_submenu)
action.perform()
