使用 Selenium 我正在尝试读取包含在“a”标签中的 href 链接的内容，这是 Quora 上的“View Upvoter”按钮（给你 upvoters 用户名列表），我在 selenium 中使用这个 python 代码，但我得到的结果总是空的，有什么建议吗？这是python代码：

inputElement = browser.find_element_by_class_name("VoterListModalLink")
inputElement.send_keys("\n") #send enter for links, bttons
print(inputElement.text)

这是 quora 按钮 html ：

 <a class="AnswerVoterListModalLink VoterListModalLink"
   href="/api /mobile_expanded_voter_list?key=zDDQQihxghH&amp;type=answer" 
   id="__w2_iXtwcOw_modal_link" target="_blank">View Upvoters
 </ a>

您与我们共享的链接中 有 5 个View Upvoters链接。

要从 DOM 中检索 href 属性，您可以先将 5 个 web 元素存储在一个 list 中，然后使用 for each 循环来提取所需的属性。

代码： 

driver.get("https://www.quora.com/Can-you-cash-out-bitcoins")

upvoter_list = driver.find_elements_by_link_text('View Upvoters')
print(len(upvoter_list))

for voter in upvoter_list:
  print(voter.get_attribute('href'))

更新 1： 

driver.maximize_window()
driver.get("https://www.quora.com/Can-you-cash-out-bitcoins")

wait = WebDriverWait(driver, 10)  

upvoter_list = driver.find_elements_by_link_text('View Upvoters')
print(len(upvoter_list))

#Clicking on first upvoter list
upvoter_list[0].click()

time.sleep(10)

#Now we will get all the names from newly opened pop up 
wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, 'div.modal_content.modal_body'))) 

upvoter_name = wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, 'span.feed_item_answer_user'))) 

print(len(upvoter_name))
for names in upvoter_name:
 print(names.text)
