【问题描述】：

我想在hotelstars.eu 上自动搜索斯图加特（德国）附近的五星级酒店，并用selenium 框架编写了一个python 脚本。我寻找了类似的问题，但没有任何效果。

这是我在单独文件 (browserDriver.py) 中的浏览器驱动程序代码：

#-*-coding:utf-8-*-
import os

from selenium import webdriver


options = webdriver.ChromeOptions()
options.add_argument('--ignore-certificate-errors')
options.add_argument('--incognito') 

chromedriver = r"\Users\simon\Documents\chromedriver_win32\chromedriver"
os.environ["webdriver.chrome.driver"] = chromedriver
driver = webdriver.Chrome(chromedriver)

还有searchAutomattecally_hotelstars_eu.py - 文件：

from selenium.webdriver.common.by import By
from selenium.webdriver.support.select import Select

import browserDriver as bd
import time

val_land = 'Germany'
val_city = 'Stuttgart'
val_radius = '100'
val_stars = '5'



bd.driver.get('https://www.hotelstars.eu/de/deutschland/service/hotelsuche/')


bd.driver.implicitly_wait(10)

# accept Cookies
bd.driver.find_element(By.ID, '564').click()

print('- - - Status: Cookies accepted')

element_land =bd.driver.find_element(By.NAME, 'country')
print(element_land.text)

all_options = element_land.find_elements(By.TAG_NAME, 'option')
for option in all_options:
    if option == val_land:
        select_land = Select(option)
        print('- - - Status: Geeeeeeeeeht')
print('- - - Status: if-Bedingung beendet')



select_land.select(By.Value, val_land)
print('- - - Status: ', select_land)


element_stadt = bd.driver.find_element(By.ID, 'city') 
element_stadt.send_keys(val_city)

element_radius = bd.driver.find_element(By.ID, 'radius') 
select_radius = Select(bd.driver.find_element_by_name('radius'))
select_radius.select_by_value(val_radius)


element_stars = bd.driver.find_element(By.ID, 'stars') 
select_stars = Select(bd.driver.find_element(By.NAME, 'stars'))
select_stars.select_by_value(val_stars)

bd.driver.find_element_by_id("sendbtn").click()

网站链接hotelstars.eu

这里是错误信息：

有人可以帮忙吗？

标签： python selenium selenium-webdriver selenium-chromedriver

【解决方案1】：

因为所需的元素在这个 iframe 中：

<iframe id="searchIframe" scrolling="no" src="/fileadmin/bsdist/theme/modules/hotelstars_search/?L=1" width="100%" height="200px" frameborder="0" style="border: 0px; height: 250px;" allowfullscreen=""></iframe>

所以你必须先切换到这个 iframe，然后才能与所需的元素进行交互。

bd.switch_to.frame(bd.find_element_by_xpath("//iframe[@id='searchIframe']"))

然后像这样与国家/地区下拉菜单互动：-

element_land = bd.driver.find_element(By.NAME, 'country')
