selenium 显示等待wait.until 常用封装 及下拉框的选择操作等

from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait as wwait
from selenium.webdriver.support import expected_conditions as EC

def wait_until(bc,locator,type=1):

    '''bc=driver,类似locator=(By.ID,'kw'),type{1:visible,2:clickable,3:frame switch}'''

    wait=wwait(bc,10,0.2)
　　
　　#等待页面元素可见，返回该页面元素

    if type==1:
        return wait.until(EC.visibility_of_element_located(locator))
　　
　　#等待页面元素可点击，返回该元素

    elif type==2:
        return wait.until(EC.element_to_be_clickable(locator))
    
　　#通过定位frame 切换到这个frame
    elif type=3:
        wait.until(EC.frame_to_be_available_and_switch_to_it(locator))

　　#切换回最外层  bc.switch_to.default_content()

from selenium.webdriver import ActionChains as AC

from selenium.webdriver.support.ui import Select
from selenium.webdriver.common.keys import Keys

#找到下拉框
select_element=Select(bc.find_element_by_xpath("//select"))

#下拉框选项的多选
select_element.select_by_index(1)
select_element.select_by_visible_text('荔枝')
select_element.select_by_value('juzi')

#取消选择
select_element.deselect_by_index(1)
select_element.deselect_by_visible_text('荔枝')
select_element.deselect_by_value('juzi')

#文本下拉框
from selenium.webdriver.common.keys import Keys
bc.find_element_by_id('select').send_keys('c')
#箭头向下选
bc.find_element_by_id('select').send_keys(Keys.ARROW_DOWN)
#回车选中
bc.find_element_by_id('select').send_keys(Keys.ENTER)

#操作单选框
berry_redio=bc.find_element_by_xpath("//input[@value='berryradio']")
berry_redio.click()
if berry_redio.selected():
 watermelonradio=bc.find_element_by_xpath("//input[@value='watermelonradio']")
 watermelonradio.click()

#复选框
先找到复选框
berry_checkbox=bc.find_element_by_xpath("//input[@value='berry']")
berry_checkbox.click()
if berry_checkbox.is_selected():
 berry_checkbox.click()  #取消选择


check_boxlist=bc.find_elements_by_xpath("//input[@name='fruit']")
for  i in check_boxlist:
 if not i.is_selected():
  i.click()
