selenium2切换窗口失败

Question

#conding=utf-8
from selenium import webdriver
import time

driver=webdriver.Chrome()
driver.implicitly_wait(10)
driver.get("http://www.baidu.com")

search_windows=driver.current_window_handle

driver.find_element_by_link_text(u'登录').click()
driver.find_element_by_link_text(u'立即注册').click()

all_handles=driver.window_handles

#进入注册窗口
for handle in all_handles:
    if handle !=search_windows:
       driver.switch_to.window(search_windows)
       print ('now registerwindow!')
       driver.find_element_by_name("account").send_keys('username')
       driver.find_element_by_name('password').send_keys('password')
       time.sleep(2)
#进入搜索窗口
for handle in all_handles:
    if handle ==search_windows:
       driver.switch_to.window(search_windows)
       print ('now sreachwindow!')
       driver.find_element_by_id('TANGRAM__PSP_2__closeBtn').click()
       driver.find_element_by_id("kw").send_keys("selenium")
       driver.find_element_by_id("su").click()
       time.sleep(2)

driver.quit()

控制台信息：

now registerwindow!

整体思路是对的，用法也比较高级；
但是代码有写错哦:
1.既然你的逻辑是如果当前handle不是搜索页面，那就跳转到注册页面，那么此处代码应改为：

#进入注册窗口
for handle in all_handles:
    if handle !=search_windows:
       driver.switch_to.window(handle)
       print ('now register window!')

2.既然你在注册页面输入，那么就应该获取注册页面的元素，而不是登录页面：

for handle in all_handles:
    if handle !=search_windows:
       driver.switch_to.window(handle)
       print ('now registerwindow!')
       driver.find_element_by_name("userName").send_keys('username')
       driver.find_element_by_name('phone').send_keys('password')
       ……
       time.sleep(2)

帮你修改了一下：

#conding=utf-8
from selenium import webdriver
import time

driver=webdriver.Chrome()
driver.implicitly_wait(10)
driver.get("http://www.baidu.com")

search_windows=driver.current_window_handle

driver.find_element_by_link_text(u'登录').click()
driver.find_element_by_link_text(u'立即注册').click()

all_handles=driver.window_handles

#进入注册窗口
for handle in all_handles:
    if handle !=search_windows:
       driver.switch_to.window(handle)
       print ('now registerwindow!')
       driver.find_element_by_name("userName").send_keys('username')
       driver.find_element_by_name('phone').send_keys('password')
       time.sleep(2)
#进入搜索窗口
for handle in all_handles:
    if handle ==search_windows:
       driver.switch_to.window(search_windows)
       print ('now sreachwindow!')
       driver.find_element_by_id('TANGRAM__PSP_2__closeBtn').click()
       driver.find_element_by_id("kw").send_keys("selenium")
       driver.find_element_by_id("su").click()
       time.sleep(2)

driver.quit()
