找到并移动一些bouton webdriver python
找到并移动一些bouton webdriver python
提问于 2019-03-05 05:59:06
我的问题是：我想找到某些元素，并填写诸如Cuántodineronecesitas和Encuántosmesesquieres devolverlo这样的价值观。我尝试了一切，但我根本做不到。
实际上，我想模拟值，并检索像TIN这样的信息。
我的网站是：https：//www.bancosantander.es/es/particulares/prestamos/prestamo-coche/simulador
我的代码：
from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
import time
chrome_options = webdriver.ChromeOptions()
chrome_options.add_argument('--headless')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument('--disable-dev-shm-usage')
chrome_options.add_argument('--start-maximized')
chrome_options.add_argument('window-size=4400x2200')
webdriver = webdriver.Chrome('chromedriver',chrome_options=chrome_options)
url = "https://www.bancosantander.es/es/particulares/prestamos/prestamo-coche/simulador"
webdriver.get(url)
webdriver.find_element_by_xpath("//button[@onclick=\"_W034_Cookie_Directive_WAR_W034_Cookie_Directiveportlet_.hidePortlet()\"]").click()
webdriver.find_element_by_xpath("//*[@class='input ng-isolate-scope ng-valid ng-dirty']")
webdriver.save_screenshot('sreenshot0.png')
我收到以下错误：
/usr/local/lib/python3.6/dist-packages/ipykernel_launcher.py:12: DeprecationWarning: use options instead of chrome_options
if sys.path[0] == '':

从我所看到的，这个元素并不总是存在。您可以使用try exceptblock 包装命令
try:
webdriver.find_element_by_xpath("//button[@onclick=\"_W034_Cookie_Directive_WAR_W034_Cookie_Directiveportlet_.hidePortlet()\"]").click()
except NoSuchElementException:
pass
或者使用find_elements并检查按钮是否存在
elements = webdriver.find_elements_by_xpath("//button[@onclick=\"_W034_Cookie_Directive_WAR_W034_Cookie_Directiveportlet_.hidePortlet()\"]")
if elements:
elements[0].click()
您还可以在此处添加显式等待，页面加载需要一些时间
try:
WebDriverWait(driver, 10).until(EC.visibility_of_element_located((By.XPATH, "//button[@onclick=\"_W034_Cookie_Directive_WAR_W034_Cookie_Directiveportlet_.hidePortlet()\"]")).click()
except TimeoutException:
pass
