Selenium元素定位-iframe

元素处于iframe中时，直接对其进行定位无效，需要先找到iframe，再进行定位

#打开浏览器

driver = webdriver.Chrome()

driver.get("http://test.abc.com")

driver.maximize_window()

# 找到iframe的xpath

xpath_iframe = '//div[@class="login-pad"]/iframe'

# 获得iframe

iframe = driver.find_element(By.XPATH, xpath_iframe)

# 跳转iframe

driver.switch_to.frame(iframe)

# 定位username输入框

xpath_username = '//input[@placeholder="请输入账号"]'

driver.find_element(By.XPATH,xpath_username).send_keys('zhangsan')

# 定位password输入框

xpath_password = '//input[@placeholder="请输入密码"]'

driver.find_element(By.XPATH, xpath_password).send_keys('password123')

time.sleep(1)

# 定位 login button

xpath_login_button = '//button[@class="login_btn"]'

driver.find_element(By.XPATH, xpath_login_button).click()

time.sleep(3)

# 登陆后首页拍照

driver.get_screenshot_as_file("../temp/screenshot/login.png")
