#go to eat24, type in zip code 10007, choose pickup and click search

#scroll up and down on page to load more of 'infinity' list

for i in range(0,3):
    driver.execute_script("window.scrollTo(0, 
document.body.scrollHeight);")
    driver.execute_script("window.scrollTo(0,0);")
    time.sleep(1)

#find menu buttons

menus_elements = driver.find_elements_by_xpath('//*[@title="View Menu"]')
#menus_element = driver.find_element_by_xpath('//*[@title="View Menu"]')
#menus_element.click()

#Problem area: Trying to iterate over menu buttons and collect menu items + prices from each. It goes to the first menu and pulls the prices/menu items, but then when it goes back to first page it says 'stale element reference' and doesn't click the next menu item


for i in range(0, len(menus_elements)):
    if menus_elements[i].is_displayed():
        menus_elements[i].click()
 #find menu items
    menu_items = driver.find_elements_by_class_name("cpa")
    menus = [x.text for x in menu_items]
#find menu prices
    menu_prices = driver.find_elements_by_class_name('item_price')
    menu_prices = [x.text for x in menu_prices]
        #pair menu items and prices
    for menu, menu_price in zip(menus, menu_prices):
        print(menu + ': ' + menu_price)
    driver.execute_script("window.history.go(-1)")
    driver.implicitly_wait(20) 

问题是在这里的最后,它进入第一个菜单并获取项目/价格,但当它返回页面时,它不会选择第二个菜单并执行相同的操作。为什么?谢谢你的建议!!!
