无法模拟< span>内的onclick javascript.使用Selenium Webdriver标记，python

问题描述

我正在尝试在以下标记处模拟onclick事件

I am trying to simulate onclick event at the following tag

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

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

此链接用于查看此链接下的更多文本.我正在使用selenium webdriver和python为该网页自动模拟此事件 http://www.tripadvisor.in/Hotel_Review-g297586-d1154547 -Reviews-Rainbow_International_Hotel-Hyderabad_Telangana.html 此网页.

This is used to see more text under this link.I am using selenium webdriver and python for simulating this event automatically for this webpage http://www.tripadvisor.in/Hotel_Review-g297586-d1154547-Reviews-Rainbow_International_Hotel-Hyderabad_Telangana.html this webpage.

任何人都可以共享一个代码段以激活此javascript事件，以便页面加载，并且我可以自动看到该链接下的全文...我尝试使用Selenium Webdriver的click()选项，但它不起作用

could anyone pls share a code snippet inorder to actiavet this javascript event so that page loads up and I can see whole text under that link automatically...I tried using click() option of selenium webdriver but it doesn't work.

推荐答案

以下是您可能以以下内容开头的想法:

Here's the idea that you may start with:

• 遍历页面上的所有评论(以id开头的id的div元素)
• 对于每个评论，单击More链接(如果存在)(跨度为moreLink类名)
• 稍作延迟后，获得完整的评论文字

• iterate over all reviews on the page (div elements with id starting with review_)
• for every review, click on the More link if it is present (span with moreLink class name)
• after a small delay, get the full review text

这是实现:

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):

Prints (the output contains all text inside each review including username and date):

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..
