上面是普通的窗口切换，下面是iframe切换
写个简单的有iframe的页面
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>py44</title> </head> <body> <h2 id="hello">hello</h2> <iframe id="i" name="f" src="http://www.testingpai.com" width="800px" height="600px"></iframe> </body> </html>
切换到iframe
import time from selenium import webdriver from selenium.webdriver import ChromeOptions from selenium.webdriver.chrome.service import Service from selenium.webdriver.common.by import By from selenium.webdriver.support.wait import WebDriverWait from selenium.webdriver.support import expected_conditions as when class TestDemo: def test_01(self): service = Service(executable_path='chromedriver_95.exe') with webdriver.Chrome(service=service) as browser: browser.implicitly_wait(5) browser.get("file:///D:/vip%E7%8F%AD%E7%BA%A7/py44/day36_%E7%AD%89%E5%BE%85%E5%92%8C%E5%88%87%E6%8D%A2/iframe_web.html") browser.find_element(By.ID, 'hello') # 必须要切换到iframe当中 iframe = browser.find_element(By.ID, 'i') browser.switch_to.frame(iframe) # iframe browser.find_element(By.XPATH, '//span[contains(text(), "排行榜")]')
## iframe
```python
iframe = driver.find_element()
driver.switch_to.frame(iframe)
# 子页面的子页面
sub_iframe = driver.find_element()
driver.switch_to.frame(sub_iframe)
# 切回主页面
page.switch_to.default_content()
# 退回到父级iframe
page.switch_to.parent_frame()
假如需要等待，iframe需要使用显性等待
