 driver.get(url)
 try:
     #登录
     driver.find_element_by_name("username").send_keys("admin")
     driver.find_element_by_name("password").send_keys("admin")
     driver.find_element_by_name("login").click()

     test_forum = driver.find_element_by_css_selector("[href='/jforum/forums/show/1.page']")
     print(test_forum.text)
     test_forum.click()

     driver.find_element_by_xpath("//a[@class='icon_new_topic']/img").click()

     """定位一组元素"""
     all = driver.find_elements_by_css_selector("input[type='checkbox']")
     num =
     for checkbox in all:
         num +=
         if num ==  or num == :
             checkbox.click()
         sleep()
     print('循环次数:',num)
     '''取消选择的√'''
