硒 Python ElementNotVisibleException

Question

我将 Selenium 与 Python 一起使用，我正在尝试填写登录表单，我已经成功完成用户名字段，但无法完成密码。这是 html:

<div class="loginNotVodafone" style="">

        <form id="loginNotVodafone" name="loginNotVodafone" action="https://urlblabla" method="post">      
          <!-- // GDPR select -->

          <fieldset>
          <input type="text" id="userFake2" name="userFake2" value="" autocomplete="off" placeholder="Username">
          <input type="hidden" id="user" name="UserName" class="hiddenTwo" value="">
          </fieldset>

          <fieldset>
          <input id="password" name="Password" value="" type="password" autocomplete="off" placeholder="Password">
          </fieldset>

        </form>
</div>

这是我的代码：

inputuser = driver.find_element_by_id("userFake2")
inputuser.send_keys('email@email.com')
sleep(1);

password = driver.find_element_by_xpath(".//fieldset[.//input[@id='password']]")
password.click()
sleep(1);
password.send_keys('password')

我总是收到错误：

selenium.common.exceptions.ElementNotVisibleException: Message: element not 
visible

回溯：

编辑： 使用此命令，我可以让光标在密码字段中闪烁：

password = driver.find_element_by_xpath("//*@id='loginNotVodafone']/fieldset[2]").click()
password.send_keys('password')

但收到错误消息：

password.send_keys('password')
AttributeError: 'NoneType' object has no attribute 'send_keys'

Answer 1

尝试使用WebDriverWait:

WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "Password")))

注意：你必须添加一些导入：

from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.wait import WebDriverWait
from selenium.webdriver.common.by import By

WebDriverWait 将等待至少 10 秒，直到元素可点击，然后才点击它。整个代码将是这样的：

inputuser = driver.find_element_by_id("userFake2")
inputuser.send_keys('email@email.com')

password = WebDriverWait(driver, 10).until(EC.element_to_be_clickable((By.ID, "Password")))
password.click()
sleep(1); # make sure, that you really need this pause
password.send_keys('password')

编辑： 你也可以尝试使用 JavaScript:

inputuser = driver.find_element_by_id("userFake2")
inputuser.send_keys('email@email.com')

password = driver.find_element_by_id("password")
driver.execute_script("arguments[0].click();", password)
sleep(1); # make sure, that you really need this pause
password.send_keys('password')

Answer 2

xpath 中存在问题，所以我为 Chrome 使用了一个名为 ChroPath 的插件，它为我提供了正确的绝对和相对路径

所以正确的命令是：

password = driver.find_element_by_xpath("/html[1]/body[1]/div[3]/div[1]/div[1]/div[1]/div[4]/form[1]/fieldset[3]/input[1]").send_keys('password')

或相对 Xpath:

password = driver.find_element_by_xpath("//form[@id='loginNotVodafone']//input[@id='password']").send_keys('password')
