python - selenium.common.exceptions.ElementNotVisibleException : Message: Element is not currently visible and so may not be interacted with

Question

目前正在努力使用 Python 登录 Twitter。

Twitter 的登录页面是 here .用户名和密码输入字段的源代码是:

<div class="LoginForm-input LoginForm-username">
<input
  type="text"
  class="text-input email-input js-signin-email"
  name="session[username_or_email]"
  autocomplete="username"
  placeholder="Phone, email or username"
/>
</div>

<div class="LoginForm-input LoginForm-password">
<input type="password" class="text-input" name="session[password]" 
placeholder="Password" autocomplete="current-password">
</div>

因此，当我使用 Selenium 模块在 Python 中编写代码时:

# -*- coding: utf-8 -*-
from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("https://twitter.com/login")
elem = driver.find_element_by_name("session[username_or_email]")
elem.clear()
elem.send_keys(username)
elem = driver.find_element_by_name("session[password]")
elem.clear()
elem.send_keys(password)
elem.send_keys(Keys.RETURN)
sleep(delay)

返回的错误:

selenium.common.exceptions.ElementNotVisibleException: Message: Element is not currently visible and so may not be interacted with

有什么帮助吗？谢谢!我已经阅读了其他类似问题的回答，但没有太大帮助。

您应该尝试使用 WebDriverWait 等待元素可见，然后再与元素交互，如下所示:-

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

wait = WebDriverWait(driver, 10)

user = wait.until(EC.visibility_of_element_located((By.NAME, "session[username_or_email]")))
user.clear()
user.send_keys(username)

pass = wait.until(EC.visibility_of_element_located((By.NAME, "session[password]")))
pass.clear()
pass.send_keys(password)

注意:- 而不是 send_keys(Keys.RETURN) 尝试使用 click() 作为登录按钮元素作为 login_button_element .click() 或在找到这些元素后尝试使用 submit() 作为 form_element.submit() 到表单元素。
