Selenium：获取下一个按钮点击内容

Question

在Quora网站上，我试图通过点击“查看upvoters”获得每个答案的upvoters名称，但我没有得到正确的结果。例如，在this Quora问题链接上你有两个答案，第一个有5个upvoters，第二个有2个。我从下面的代码得到的结果是5,5。

all_upvotes= browser.find_elements_by_class_name('ExpandedVoterListItem')
for p in all_upvotes:
    p.click()
    time.sleep(10)

    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'))) 

    time.sleep(10)
    print ('number of upvoters found for this answer %d' % len(upvoter_name)) 
    # print upvoters names
    for line in upvoter_name:
           print(line.text)

Answer 1

您似乎每次都不选择“查看Upvoters”链接，至少在您提供的脚本中是这样。而是使用以下操作顺序：

all_upvotes= browser.find_elements_by_link_text('View Upvoters') # Finds all "View Upvoters" buttons (they are links actually)
for p in all_upvotes:

    p.click() # Opens list of upvoters

    # No need to sleep or wait for anything else, just wait for items you want, namely the name of upvoter (which is again a link):
    upvoter_name = wait.until(EC.presence_of_all_elements_located((By.CSS_SELECTOR, 'a.user')))

    print ('number of upvoters found for this answer %d' % len(upvoter_name)) 

    # print upvoters names
    for line in upvoter_name:
        print(line.text)

    # Now we need to close list of upvoters, to open the next one on next iteration of the loop:
    close_button = wait.until(EC.visibility_of_element_located((By.CSS_SELECTOR, 'span.modal_close'))) 
    close_button.click()
