selenium webdriver可以通过获取页面标题，再跟据标题去切换浏览器窗口，代码如下：
#encoding=utf-8 import unittest import time import chardet from selenium import webdriver class VisitSogouByIE(unittest.TestCase): def setUp(self): # 启动chrome浏览器 self.driver = webdriver.Chrome(executable_path = "e:\chromedriver") def test_operateWindowHandle(self): url = "http://www.baidu.com" self.driver.get(url) # 获取当前窗口句柄 now_handle = self.driver.current_window_handle # 打印当前获取的窗口句柄 print now_handle # 百度搜索输入框中输入“selenium” self.driver.find_element_by_id("kw").send_keys("w3cschool") # 点击搜索按钮 self.driver.find_element_by_id("su").click() # 导入time包 import time # 等待3秒，以便网页加载完成 time.sleep(3) # 点击w3school在线教育链接 self.driver.find_element_by_xpath('//div[@id="1"]//a[text()="w3"]').click() time.sleep(5) # 获取所有窗口句柄 all_handles = self.driver.window_handles # 循环遍历所有新打开的窗口句柄，也就是说不包括主窗口 for handle in all_handles: self.driver.switch_to.window(handle) print type(self.driver.title) print self.driver.title if self.driver.title == u"w3school 在线教程": # 点击HTML5链接 self.driver.find_element_by_link_text('HTML5').click() time.sleep(3) if self.driver.title == u"w3cschool_百度搜索": time.sleep(2) self.driver.find_element_by_id("kw").clear() self.driver.find_element_by_id("kw").send_keys(u"光荣之路自动化测试培训") self.driver.find_element_by_id("su").click() time.sleep(5) def tearDown(self): # 退出IE浏览器 self.driver.quit() if __name__ == '__main__': unittest.main()
