无法找到元素Selenium WebDriver [英] Unable to locate element selenium webdriver

问题描述

我正在尝试抓取以下网站: https://www.bancosantander.es/es/particulares/prestamos/prestamo-coche/simulador

I'm trying to scrape the following website: https://www.bancosantander.es/es/particulares/prestamos/prestamo-coche/simulador

我要做什么:

通过移动滑块来模拟数量和持续时间.我正在尝试使用网络驱动程序找到它们.

Simulate the amount and duration by moving the slider. I'm trying to locate them with my webdriver.

但是我不能，事实上我已经开始抓取了.

But I can't, in fact I'm starting to scraping.

出现的错误如下:

/usr/local/lib/python3.6/dist-packages/ipykernel_launcher.py:12: DeprecationWarning: use options instead of chrome_options
  if sys.path[0] == '':

webdriver = webdriver.Chrome('chromedriver',chrome_options=chrome_options)
webdriver.maximize_window()
url = "https://www.bancosantander.es/es/particulares/prestamos/prestamo-coche/simulador"
webdriver.get(url)

try:
    webdriver.find_element_by_xpath("//button[@onclick=\"_W034_Cookie_Directive_WAR_W034_Cookie_Directiveportlet_.hidePortlet()\"]").click()
except NoSuchElementException:
    pass
webdriver.save_screenshot('sreenshot0.png')
webdriver.find_element_by_xpath("//*[@class='res r1']")

webdriver.save_screenshot('sreenshot0.png')

推荐答案

您可以尝试以下操作来输入值

You can try the following for entering your values

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
from selenium.webdriver.common.keys import Keys

url = 'https://simuladores.bancosantander.es/SantanderES/loansimulatorweb.aspx?por=webpublica&prv=publico&m=100&cta=1&ls=0#/t0'
driver = webdriver.Chrome()
driver.get(url)

amount =  WebDriverWait(driver,10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "#amount")))
amount.clear()
amount.send_keys(6000)

WebDriverWait(driver, 30).until(lambda driver: driver.execute_script('return jQuery.active') == 0)

term =  WebDriverWait(driver,10).until(EC.presence_of_element_located((By.CSS_SELECTOR, "#term")))
term.clear()
term.send_keys('60 meses')
term.send_keys(Keys.TAB)
currentCuota = driver.find_element_by_css_selector('.r1 span').text
WebDriverWait(driver, 10).until(lambda driver: driver.execute_script('return jQuery.active') == 0)
while driver.find_element_by_css_selector('.r1 span').text == currentCuota:
    continue

print('Tu cuota mensual: ' + driver.find_element_by_css_selector('.r1 span').text)
