selenium - webdriver 多窗口切换 switch_to.window()

页面操作中,点击某个链接会打开新的窗口,定位新窗口中的元素,需要跳转到新窗口操作(即使已经打开新的窗口,你的句柄和title还是前面窗口的),可以使用以下方法:

  • current_window_handle
  • window_handles
  • switch_to.window(handle)

例子:

1. 打开百度首页,点击登录按钮,点击立即注册按钮,打开新的窗口

2. 跳转到注册窗口,在注册窗口进行操作

3. 跳回到百度首页,点击登录弹出框的关闭按钮,在百度首页进行操作

 1 from selenium import webdriver
 2 import time
 3 
 4 driver = webdriver.Chrome()
 5 driver.maximize_window()
 6 driver.get('http://www.baidu.com')
 7 
 8 search_window = driver.current_window_handle           # 获取当前窗口句柄
 9 time.sleep(3)
10 driver.find_element_by_link_text('登录').click()
11 time.sleep(3)
12 driver.find_element_by_link_text('立即注册').click()
13 
14 all_window_handles = driver.window_handles             # 获取当前所有打开窗口的句柄
15 
16 for handle in all_window_handles:
17     if handle != search_window:
18         driver.switch_to.window(handle)    # 跳转到注册窗口
19         driver.find_element_by_id('TANGRAM__PSP_4__userName').send_keys('jda')
20         driver.find_element_by_id('TANGRAM__PSP_4__phone').send_keys('13100000000')
21         driver.find_element_by_id('TANGRAM__PSP_4__password').send_keys('fda')
22         time.sleep(3)
23 
24 for handle in all_window_handles:
25     if handle == search_window:
26         driver.switch_to.window(handle)    # 跳转到百度首页窗口
27         driver.find_element_by_id('TANGRAM__PSP_4__closeBtn').click()
28         driver.find_element_by_id('kw').send_keys('zhangyang')
29         driver.find_element_by_id('su').click()
30         time.sleep(3)
31 
32 driver.quit()

 

使用js,打开新的tab页面

js1 = 'window.open("https://163.com")'
driver.execute_script(js1)
js = 'window.open("{}")'.format("http://www.baidu.com")
js = f'window.open("{"http://www.163.com"}")'

 

 

例子:循环打开三个页面,并打印handle和title

from selenium import webdriver
import time


driver = webdriver.Chrome()
driver.maximize_window()
driver.implicitly_wait(10)

urls = ['https://www.baidu.com', 'http://www.163.com', 'http://www.qq.com']

for url in urls:
    js = 'window.open("{}")'.format(url)
    driver.execute_script(js)

    driver.switch_to.window(driver.window_handles[-1])
    print(driver.window_handles)
    print(driver.current_window_handle)
    print(driver.title)


time.sleep(3)
driver.quit()
