1.用新学的Select类方法实现，选择抖音，但是要判断，如果抖音没被选择，才会去选择

from selenium import webdriver
from time import sleep
from selenium.webdriver.support.select import Select

driver = webdriver.Chrome()
url = ‘file://C:/select.htm‘
driver.get(url)
driver.maximize_window()
sleep(2)

下拉框_loc = ‘//select’
下拉框 = driver.find_element_by_xpath(下拉框_loc)
print(Select(下拉框).first_selected_option.text)

if Select(下拉框).first_selected_option.text == ‘抖音’:
print(‘抖音本身已被选择’)
else:
Select(下拉框).select_by_visible_text(‘抖音’)

sleep(2)
driver.quit()

2.用鼠标键盘模拟事件，去完成今日头条的选择

from selenium import webdriver
from time import sleep
from selenium.webdriver import ActionChains
from selenium.webdriver.common.keys import Keys

driver = webdriver.Chrome()
url = ‘file://C:/select.htm‘
driver.get(url)
driver.maximize_window()
sleep(2)

xia_la_kuang_loc = ‘//select’
xia_la_kuang = driver.find_element_by_xpath(xia_la_kuang_loc)
xia_la_kuang.click()
# ActionChains(driver).key_down(Keys.DOWN).key_up(Keys.DOWN).perform()
ActionChains(driver).send_keys(Keys.DOWN).send_keys(Keys.ENTER).perform()

sleep(2)
driver.quit()

3.百度高级搜索里，【时间：限定要搜索的网页的时间是】选择最近一年

from selenium import webdriver
#driver=webdriver.Chrome()
##__隐式等待
#driver.implicitly_wait(10)
#driver.maximize_window()
#driver.get(‘https://www.juhe.cn/‘)
##智能等待，显式等待
#__from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.support import expectedconditions as EC
#from selenium.webdriver.support.expectedconditionsimportvisibility_of_element_located
_#from selenium.webdriver.support.expectedconditionsimportframe_to_be_available_and_switch_to_it
##WebDriverWait()有两个参数：1、你目前所使用的driver；2、智能等待的设置时间
##.until(条件句)配合WebDriverWait的使用
##定义元组形式的定位器，如果使用xpath表达元素，就写By.XPATH
#__from selenium.webdriver.common.by import By
#弹出的窗口_frame_loc=（By.XPATH,’//iframe[@id=”layui-layer-iframe1”]’）

##frame_to_be_available_and_switch_to_it()这个条件方法，参数填写你要等待和切入的frame元素
#wait=WebDriverWait(driver,20)
Wait.until(frame_to_be_available_and_switch_to_it(弹出的窗口_frame_loc))

##visibility_of_element_located()这个条件方法，参数填写你要智能等待的元素的“元组类型”的定位器表达式,
##如果在设置的时间内，等待到元素，则返回元素，反之，Python会抛出“等待超时”这个异常
#__wait=WebDriverWait(driver,20)

#手机号码_loc=(By.XPATH,’//input[@id=”mobilephone”]’)
##直接在visibility_of_element_located()方法后面放入“元组形态”的定位器表达式
##等待成功，则返回元素
#手机号码=wait.until(visibility_of_element_located(手机号码_loc))
#print(‘元素长这样：{}’.format(手机号码))
#手机号码.send_keys(‘13812345678’)
