例: from selenium import webdriver b = webdriver.Firefox() b.get("http://edu.51cto.com/courselist/index.html") ele = b.find_element_by_link_text("找课程") #定位找课程元素
from selenium.webdriver.common.actiton_chains import ActionChains
ActionChains(b).move_to_element(ele).perform() #模拟鼠标停在"找课程"上 出现下拉菜单 ele1 = b.find_element_by_link_text("人工智能") #在下拉菜单中定位"人工智能" ele1.click()
