1、iframe切换方式一
- 首先先确定定位元素在iframe元素中，打开网页https://ke.qq.com/点击登录按钮，按F12,定位账户密码登录元素
- 切换到指定的iframe元素中，如下
1 from selenium import webdriver 2 from selenium.webdriver.support.wait import WebDriverWait 3 from selenium.webdriver.support import expected_conditions as EC 4 from selenium.webdriver.common.by import By 5 import time 6 7 driver=webdriver.Chrome() 8 # 访问一个网页 9 driver.get("https://ke.qq.com/") 10 driver.maximize_window() 11 driver.find_element_by_id('js_login').click() 12 # 等待//div[@class='ptlogin-wrap']//i[@class='icon-font i-qq']元素出现 13 WebDriverWait(driver,20).until(EC.visibility_of_element_located((By.XPATH,"//div[@class='ptlogin-wrap']//i[@class='icon-font i-qq']"))) 14 # 点击//div[@class='ptlogin-wrap']//i[@class='icon-font i-qq']元素 15 driver.find_element_by_xpath("//div[@class='ptlogin-wrap']//i[@class='icon-font i-qq']").click() 16 # 等待iframe元素出现 17 WebDriverWait(driver,20).until(EC.visibility_of_element_located((By.NAME,"login_frame_qq"))) 18 # 切换iframe 19 driver.switch_to.frame('login_frame_qq') #name属性方式定位 20 time.sleep(0.5)#切换到iframe元素过程等待0.5秒 21 # 等待id为switcher_plogin的元素出现 22 WebDriverWait(driver,10).until(EC.visibility_of_element_located((By.ID,'switcher_plogin'))) 23 driver.find_element_by_id('switcher_plogin').click() 24 # Switches focus to the specified frame, by index, name, or webelement. 25 ''' 26 :Usage: 27 driver.switch_to.frame('frame_name')#通过name属性 28 driver.switch_to.frame(1)#通过index 从1开始 29 driver.switch_to.frame(driver.find_elements_by_tag_name("iframe")[0])#通过其他元素定位方式切换iframe find_elements_by_tag_name 30 ''' 31 # driver.switch_to.frame(1)#index方式定位 32 # driver.switch_to.frame(driver.find_element_by_xpath('//iframe[@name="login_frame_qq"]'))#其他定位元素的方式，xpath方式定位
2、iframe切换方式二
# iframe方式二切换,#直接在WebDriverWait中使用函数frame_to_be_available_and_switch_to_it，切换到iframe中 WebDriverWait(driver,20).until(EC.frame_to_be_available_and_switch_to_it('login_frame_qq'))
#等待0.5秒 time.sleep(0.5)
3、从iframe当中回到默认的页面当中 driver.switch_to.default_content()
1 from selenium import webdriver 2 from selenium.webdriver.support.wait import WebDriverWait 3 from selenium.webdriver.support import expected_conditions as EC 4 from selenium.webdriver.common.by import By 5 import time 6 7 driver=webdriver.Chrome() 8 # 访问一个网页 9 driver.get("https://ke.qq.com/") 10 driver.maximize_window() 11 driver.find_element_by_id('js_login').click() 12 # 等待//div[@class='ptlogin-wrap']//i[@class='icon-font i-qq']元素出现 13 WebDriverWait(driver,20).until(EC.visibility_of_element_located((By.XPATH,"//div[@class='ptlogin-wrap']//i[@class='icon-font i-qq']"))) 14 # 点击//div[@class='ptlogin-wrap']//i[@class='icon-font i-qq']元素 15 driver.find_element_by_xpath("//div[@class='ptlogin-wrap']//i[@class='icon-font i-qq']").click() 16 # 等待iframe元素出现 17 WebDriverWait(driver,20).until(EC.visibility_of_element_located((By.NAME,"login_frame_qq"))) 18 # # 切换iframe 19 driver.switch_to.frame('login_frame_qq') #name属性方式定位 20 time.sleep(0.5)#切换到iframe元素过程等待0.5秒 21 # 等待id为switcher_plogin的元素出现 22 WebDriverWait(driver,10).until(EC.visibility_of_element_located((By.ID,'switcher_plogin'))) 23 driver.find_element_by_id('switcher_plogin').click() 24 # Switches focus to the specified frame, by index, name, or webelement. 25 ''' 26 :Usage: 27 driver.switch_to.frame('frame_name')#通过name属性 28 driver.switch_to.frame(1)#通过index 从1开始 29 driver.switch_to.frame(driver.find_elements_by_tag_name("iframe")[0])#通过其他元素定位方式切换iframe find_elements_by_tag_name 30 ''' 31 32 # driver.switch_to.frame(1)#index方式定位 33 # driver.switch_to.frame(driver.find_element_by_xpath('//iframe[@name="login_frame_qq"]'))#其他定位元素的方式，xpath方式定位 34 35 # iframe方式二切换,#直接在WebDriverWait中使用函数frame_to_be_available_and_switch_to_it，切换到iframe中 36 # WebDriverWait(driver,20).until(EC.frame_to_be_available_and_switch_to_it('login_frame_qq')) 37 # time.sleep(0.5) 38 39 # 从iframe当中回到默认的页面当中 40 driver.switch_to.default_content() 41 time.sleep(1) 42 driver.find_element_by_xpath("//a[@id='login_close']//i[@class='icon-font i-close']").click() 43 driver.find_element_by_id('js_login').click()
备注：iframe只能一层一层的切进去，不能跳级切换
# 跳到上一级的iframe中，使用以下方法
driver.switch_to.parent_frame()
