的Python和硒：元素目前相互作用，不得操纵

我有点新硒，所以尝试后登录到Quora的网站：的Python和硒：元素目前相互作用，不得操纵

# 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()

我得到这个错误：

Traceback (most recent call last): ...

File "quora.py", line 39, in log_in email_field_element.clear()

File "/home/annieshlepak/work/QuoraAutomatization/env/lib/python3.5/site-packages/selenium/webdriver/remote/webelement.py", line 92, in clear self._execute(Command.CLEAR_ELEMENT) ...

没有与name="email"属性的两个input元素（你可以用len(driver.find_elements_by_xpath(email_field_xpath))检查）

尝试通过索引

来定位需要的（第二个）元件

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"]'

谢谢！指定XPath解决了问题！ –

@AnnieShlepak注意'driver.find_element_by'和'EC.presence_of_element_located'并不意味着元素是可见的，只是它存在于DOM中。您需要使用'visibility_of' [预期条件]（https://seleniumhq.github.io/selenium/docs/api/py/webdriver_support/selenium.webdriver.support.expected_conditions.html）或'is_displayed（）'功能。 – Guy
