2019-03-27 下拉菜单元素定位

案例：在携程网页面选择指定的房间数和酒店级别。

1. 根据选项元素标签定位

from selenium import webdriver

from time import sleep

driver = webdriver.Firefox()

driver.get("https://www.ctrip.com/")

sleep(4)

# 根据option标签来定位（7间三星级/舒适）

# driver.find_elements_by_tag_name('option')[6].click()

driver.find_elements_by_css_selector("[value='7']")[0].click()

sleep(2)

driver.quit()

2. 使用select类定位

fromselenium import webdriver

from time import sleep

from selenium.webdriver.support.ui import Select

driver = webdriver.Firefox()

driver.get("https://www.ctrip.com/")

sleep(4)

# 利用Select类来定位（7间三星级/舒适）roomCount=Select(driver.find_element_by_css_selector("#J_roomCountList"))

# roomCount.select_by_index(6)

# roomCount.select_by_visible_text("7间")

roomCount.select_by_value("7")

star = Select(driver.find_element_by_css_selector("[name='Star']"))

# star.select_by_index(3)

# star.select_by_visible_text("三星级/舒适")

star.select_by_value("3")

sleep(2)

driver.quit()
