Python & Selenium：元素当前不可交互且可能无法操作

Question

我对 Selenium 有点陌生，所以在尝试登录 Quora 网站后：

# gets email and password from json
    with open('config.json') as f:
        login_data = json.load(f)
    email = login_data['email']
    password = login_data['pass']

    email_field_xpath = "//input[@name='email']"
    password_field_xpath = "//input[@name='password']"
    login_button_xpath = "//input[@value='Login']"

    # webdriver's going to wait max 10 seconds for email's field, password field, login button to display
    email_field_element = WebDriverWait(driver, 10).until(
        lambda driver: driver.find_element_by_xpath(email_field_xpath))
    password_field_element = WebDriverWait(driver, 10).until(
        lambda driver: driver.find_element_by_xpath(password_field_xpath))

    email_field_element.clear()
    email_field_element.send_keys(email)
    password_field_element.clear()
    password_field_element.send_keys(password)

    # wait till element is visible before interaction
    login_button_element = WebDriverWait(driver, 10).until(
        EC.presence_of_element_located((By.XPATH, login_button_xpath)))
    login_button_element.click()

我遇到了这个错误：

Answer 1

有两个input元素带有name="email"属性（你可以用len(driver.find_elements_by_xpath(email_field_xpath))查看）

尝试通过索引定位所需的（第二个）元素

driver.find_elements_by_xpath(email_field_xpath)[1].clear()

或者使用更具体的XPath：

email_field_xpath = '//div[@class="form_column"]/input[@name="email"]'
