无法模拟内部使用Selenium webdriver的<span>标签，蟒蛇

问题描述：

我想在下面的标签无法模拟内部使用Selenium webdriver的<span>标签，蟒蛇

跨度类= “taLnk hvrIE6 tr165579546 moreLink ulBlueLinks” 的onclick =“ta.util.cookie模拟onclick事件的onclick的JavaScript。 setPIDCookie（2247）; ta.call（'ta.servlet.Reviews.expandReviews'，event，this，'review_165579546'，'1'，2247）“> 更多

这是用来在这个下面看到更多的文字link.I使用硒webdriver和python模拟这个事件自动为这个网页 http://www.tripadvisor.in/Hotel_Review-g297586-d1154547-Reviews-Rainbow_International_Hotel-Hyderabad_Telangana.html这个网页。

任何人都可以共享一个代码片段，以actiavet此JavaScript事件，以便页面加载，我可以看到整个文本下的链接自动...我尝试使用selenium webdriver的点击（）选项，但它没有工作。

答

这并获得成功对我来说：

from selenium import webdriver 

url = 'http://www.tripadvisor.in/Hotel_Review-g297586-d1154547-Reviews-Rainbow_International_Hotel-Hyderabad_Telangana.html' 

browser = webdriver.Firefox() 
browser.get(url) 
li = browser.find_element_by_css_selector('#PERSISTENT_TAB_HR .tabs_pers_content li:nth-child(2)') 
li.click()

答

这里，你可能会开始的想法：

遍历网页上的所有评论（div元素与id开始review_）
对于每个评论，点击More链接如果它存在（范围与moreLink类名称）
小的延迟之后，得到充分的评论文章

这里的实现：

import time 
from selenium import webdriver 
from selenium.common.exceptions import NoSuchElementException, TimeoutException 
from selenium.webdriver.common.by import By 
from selenium.webdriver.support.ui import WebDriverWait 
from selenium.webdriver.support import expected_conditions as EC 

driver = webdriver.Firefox() 
driver.get("http://www.tripadvisor.com/Hotel_Review-g297586-d1154547-Reviews-Rainbow_International_Hotel-Hyderabad_Telangana.html") 

for review in driver.find_elements_by_xpath('//div[starts-with(@id, "review_")]'): 
    try: 
     more = WebDriverWait(review, 3).until(EC.presence_of_element_located((By.CLASS_NAME, 'moreLink'))) 
     if more.is_displayed(): 
      more.click() 
      time.sleep(1) 
    except (NoSuchElementException, TimeoutException): 
     pass 

    full_review = review.find_element_by_class_name('dyn_full_review') 
    print full_review.text 
    print "----"

Reviewed August 15, 2014 
I checked on price was high but cracked a deal 
Poor hygiene in corridor & so in rooms. Washroom pipes were leaking. AC water dripping in washroom. 
First I was given a room to which my surprise found window pane was missing after complaining room got changed. 
They are cheating ppl only good thing abt hotel is the spot & is damn opposite Nilofer cafe which serves delicious tea,coffee & bakery products. 
There is a guy named khwaja who was very helpful. Front @ reception guy was stupid..in one midnight , power went off & to my surprise they don't have power back up..
