from selenium import webdriver
from selenium.webdriver.support.ui import WebDriverWait
import time

browser = webdriver.Chrome()
browser.set_window_size(900, 900) # 根据桌面分辨率来定

打开淘宝页面

browser.get("https://www.taobao.com/")

获取淘宝页面的 title和handle信息

taobaoWindowHandle = browser.current_window_handle
taobaoTitle = browser.title
print(f"1. taobaoTitle = {taobaoTitle}, taobaoWindowHandle = {taobaoWindowHandle}")

打开路由器配置页面 http://172.16.0.1

js = 'window.open("http://172.16.0.1");'
browser.execute_script(js)
time.sleep(2)

如果没有switch做窗口切换的话，即使有打开新的窗口，浏览器还是会focus在原来的窗口

print(f"2. routing Configure Page had been opened, currentTitle = {browser.title}, currentHandle = {browser.current_window_handle}")

拿到所有的窗口

allHandles = browser.window_handles
print(f"3. allHandles = {allHandles}")

第一种思路：按照handle，从淘宝窗口切换到路由器配置窗口

routeWindowHandle = 0
routeTitle = 'None'
for handle in allHandles:
if handle != browser.current_window_handle:
browser.switch_to_window(handle)
routeWindowHandle = browser.current_window_handle
routeTitle = browser.title
break
print(f"4. switch to routeWindow, routeWindowHandle = {routeWindowHandle}, routeTitle = {routeTitle}, currentHandle = {browser.current_window_handle}, currentTitle = {browser.title}")

第二种思路：当然还有一种方法是根据窗口的title进行切换

从路由器配置窗口，切换回淘宝窗口

for handle in allHandles:
if browser.title.find("淘宝网") == -1:
browser.switch_to_window(handle)
print(f"5. switch to taobaoWindow, taobaoWindowHandle = {taobaoWindowHandle}, taobaoTitle = {taobaoTitle}, currentHandle = {browser.current_window_handle}, currentTitle = {browser.title}")

time.sleep(30)

第三种思路：按照windowHandle切换，切换到taobao窗口

browser.switch_to_window(taobaoWindowHandle)
print(f"6. switch back to taobao window, currentHandle = {browser.current_window_handle}, taobaoWindowHandle = {taobaoWindowHandle}, routeWindowHandle = {routeWindowHandle}")

time.sleep(10)
browser.quit()
