Selenium 无法获取 select 结果

Question

我是 selenium 的新手，正在尝试从站点（代码中的 link）获取 select 标签的值，但每当我尝试获取 select 标签时它 returns 一个空字段。

我的代码


from selenium import webdriver
from selenium.webdriver.support.ui import Select

driver = webdriver.Chrome('chromedriver',chrome_options=chrome_options)

url = 'https://lifeinsurance.adityabirlacapital.com/about-us/public-disclosure'
driver.get(url)

select = Select(driver.find_element_by_id("select-public-year"))

print([option.text for option in select.options])
# Output: ['']

当我查看页面源代码时，它显示了以下内容：

<select Name="selectPublicYear" class="demo-default select selectized selectPublicYear" id="select-public-year" name="SelectedYear">
  <option value="2020-2021">2020-2021</option>
  <option value="2019-2020">2019-2020</option>
  <option value="2018-2019">2018-2019</option>
  <option value="2017-2018">2017-2018</option>
  <option value="2016-2017">2016-2017</option>
  <option value="2015-2016">2015-2016</option>
  <option value="2014-2015">2014-2015</option>
  <option value="2013-2014">2013-2014</option>
  <option value="2012-2013">2012-2013</option>
  <option value="2011-2012">2011-2012</option>
  <option value="2010-2011">2010-2011</option>
  <option value="2009-2010">2009-2010</option>
  <option value="2008-2009">2008-2009</option>
  <option value="2007-2008">2007-2008</option>
  <option value="2006-2007">2006-2007</option>
  <option value="2005-2006">2005-2006</option>
</select>

任何提示或帮助将不胜感激。

Answer 1

这似乎是同步问题。我建议使用 WebDriverWait() 并等待 element_to_be_clickable()

select = Select(WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.ID,"select-public-year"))))

print([option.text for option in select.options])

您需要导入以下库

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

使用 java 测试快照，因为我的工作机器中没有 python。

Answer 2

<select> 标签具有 style="display: none;" 属性，因此这不是您想要的元素。

提取文本，例如2020-2021，来自所有 <class="option"> 使用 and python you have to induce for visibility_of_all_elements_located() and you can use either of the following :

使用CSS_SELECTOR:

driver.get('https://lifeinsurance.adityabirlacapital.com/about-us/public-disclosure')
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.CSS_SELECTOR, "div.selectize-input.items.full.has-options.has-items"))).click()
print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.CSS_SELECTOR, "div.selectize-dropdown-content div.option")))])

使用XPATH:

driver.get('https://lifeinsurance.adityabirlacapital.com/about-us/public-disclosure')
WebDriverWait(driver, 20).until(EC.element_to_be_clickable((By.XPATH, "//div[@class='selectize-input items full has-options has-items']"))).click()
print([my_elem.text for my_elem in WebDriverWait(driver, 20).until(EC.visibility_of_all_elements_located((By.XPATH, "//div[@class='selectize-dropdown-content']//div[contains(@class, 'option')]")))])

控制台输出：

['2020-2021', '2019-2020', '2018-2019', '2017-2018', '2016-2017', '2015-2016', '2014-2015', '2013-2014', '2012-2013', '2011-2012', '2010-2011', '2009-2010', '2008-2009', '2007-2008', '2006-2007', '2005-2006']

注意：您必须添加以下导入：

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