无法找到元素selenium webdriver

Question

我正试图刮掉以下网站：https://www.bancosantander.es/es/particulares/prestamos/prestamo-coche/simulador

我正在尝试做什么：

通过移动滑块来模拟量和持续时间。我正试图用我的webdriver找到它们。

但我不能，事实上我开始刮痧了。

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] == '':

Answer 1

您可以尝试以下操作来输入您的值

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)

Answer 2

由于类名中的空格，您的xpath无法正常工作。不确定这是否是唯一的问题但是问题。如果该类名称正确，则以下行应该找到您的元素。

webdriver.find_element_by_css_selector('div.res.r1')
