无法在内部模拟onclick javascript<；span>；使用SeleniumWebDriver、python标记

我试图在下面的标记处模拟onclick事件

span class=“taLnk hvrIE6 tr165579546 moreLink ulBlueLinks”onclick=“ta.util.cookie.setPIDCookie（2247）；ta.call（'ta.servlet.Reviews.expandReviews'，事件，this，'review_165579546'，1'，2247）”> 更多

这用于查看此链接下的更多文本。我正在使用SeleniumWebDriver和python为此网页自动模拟此事件 这个网页

---

任何人都可以共享一段代码片段来激活此javascript事件，以便页面加载，我可以自动查看该链接下的全部文本…我尝试使用selenium webdriver的click（）选项，但无效。

这为我提供了窍门：

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()

---

您可以从以下想法开始：

• 迭代页面上的所有评论（id为

  id

  的div元素以

  review\uu

  开头）
• 对于每次审阅，如果存在

  More

  链接，请单击该链接（span with

  moreLink

  类名）
• 稍作延迟后，获得完整的复习文本

以下是实现：

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 "----"

打印（输出包含每个评论中的所有文本，包括用户名和日期）：

希望这能让你更清楚

“Horrible”
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..
