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

# 等待元素可见
wait = WebDriverWait(driver, 10)
element = wait.until(EC.visibility_of_element_located((By.ID, 'element_id')))

element = driver.find_element_by_id('element_id')
driver.execute_script("arguments[0].scrollIntoView(true);", element)

# 切换到iframe
driver.switch_to.frame('iframe_id')

# 查找元素
element = driver.find_element_by_id('element_id')

# 切回主文档
driver.switch_to.default_content()
