Python Selenium按钮单击无效

Question

我正在尝试从Seeking Alpha下载文章。由于许多文章仅是订阅者专有的，因此我必须先登录才能查看和下载这些文章。我使用的代码如下。我的问题是click()没有任何作用。手动登录后，效果很好。

# open website
url_lib = 'https://seekingalpha.com'
driver.get(url_lib)

# sign in
sign_in = driver.find_element_by_id('sign-in')
sign_in.click()

# id and pw
sign_id = driver.find_element_by_id('authentication_login_email')
sign_id.send_keys(Email address)
time.sleep(2)

sign_pw = driver.find_element_by_id('authentication_login_password')
sign_pw.send_keys(Password)
time.sleep(2)

# click submit button
submit_button = driver.find_element_by_id('log-btn')
submit_button.click()

任何建议将不胜感激！预先感谢！

所需元素是JavaScript启用的元素，因此您必须为所需element_to_be_clickable引入 WebDriverWait ，并且可以使用以下解决方案：

• 代码块：

  from selenium import webdriver
  from selenium.webdriver.support.ui import WebDriverWait
  from selenium.webdriver.common.by import By
  from selenium.webdriver.support import expected_conditions as EC
  
  options = webdriver.ChromeOptions()
  options.add_argument("start-maximized")
  # options.add_argument("disable-infobars")
  options.add_argument("--disable-extensions")
  driver = webdriver.Chrome(chrome_options=options, executable_path=r'C:\WebDrivers\chromedriver.exe')
  driver.get("https://seekingalpha.com")
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "a#sign-in"))).click()
  WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "input.form-control#authentication_login_email"))).send_keys("AnnieQW")
  driver.find_element_by_css_selector("input.form-control#authentication_login_password").send_keys("AnnieQW")
  driver.find_element_by_css_selector("input.orange-btn[value='Sign in']").click()
