Question

使用硒我正在尝试读取包含在a标记中的href链接的内容，该标记是Quora上的“查看Upvoter”按钮（为您提供upvoters用户名列表），我正在selenium中使用此python代码，但是我得到的结果始终是空的，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)

这里是“ 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>

链接到网站：https://www.quora.com/Can-you-cash-out-bitcoins

Answer 1

您与我们共享的链接中有5个查看支持者链接。

要从DOM检索href属性，您可以先在列表中存储5个Web元素，然后对每个循环使用a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)
