How to get html with javascript rendered sourcecode by using selenium

I run a query on one web page, then I get a result URL. If I right-click see HTML source, I can see the HTML code generated by JS. If I simply use urllib, python cannot get the JS code. So I see some solutions using selenium. Here's my code:

from selenium import webdriver

url = 'http://www.archives.com/member/Default.aspx?_act=VitalSearchResult&lastName=Smith&state=UT&country=US&deathYear=2004&deathYearSpan=10&location=UT&activityID=9b79d578-b2a7-4665-9021-b104999cf031&RecordType=2'

driver = webdriver.PhantomJS(executable_path='C:\python27\scripts\phantomjs.exe')

driver.get(url)

print driver.page_source

>>> <html><head></head><body></body></html>        

Obviously, It's not right!!

Here's the source code I need in right-click windows, (I want the INFORMATION part)

</script></div><div class="searchColRight"><div id="topActions" class="clearfix 

noPrint"><div id="breadcrumbs" class="left"><a title="Results Summary"

href="Default.aspx?    _act=VitalSearchR ...... <<INFORMATION I NEED>> ... 

to view the entire record.</p></div><script xmlns:msxsl="urn:schemas-microsoft-com:xslt">

        jQuery(document).ready(function() {

            jQuery(".ancestry-information-tooltip").actooltip({

href: "#AncestryInformationTooltip", orientation: "bottomleft"});

        });

=========== So my question is =============== How to get the information generated by JS?

I have had the same problem and I solved it using the below code:

  1. First, execute_script

driver=webdriver.Chrome()

driver.get(urls)

innerHTML = driver.execute_script("return document.body")

#print(driver.page_source)

2. Second, parse HTML using beautifulsoup(You can Downloaded beautifulsoup by pip command)

 import bs4    #import beautifulsoup

 import re

 from time import sleep

 sleep(1)      #wait one second 

 root=bs4.BeautifulSoup(innerHTML,"lxml") #parse HTML using beautifulsoup

 viewcount=root.find_all("span",attrs={'class':'short-view-count style-scope yt-view-count-renderer'})   #find the value which you need.

3. Third, print out the value you need

 for span in viewcount:

    print(span.string) 

Complete code

from selenium import webdriver

import lxml

urls="http://www.archives.com/member/Default.aspx?_act=VitalSearchResult&lastName=Smith&state=UT&country=US&deathYear=2004&deathYearSpan=10&location=UT&activityID=9b79d578-b2a7-4665-9021-b104999cf031&RecordType=2"

driver = webdriver.PhantomJS()

##driver=webdriver.Chrome()

driver.get(urls)

innerHTML = driver.execute_script("return document.body")

##print(driver.page_source)

import bs4

import re

from time import sleep

sleep(1)

root=bs4.BeautifulSoup(innerHTML,"lxml")

viewcount=root.find_all("span",attrs={'class':'short-view-count style-scope yt-view-count-renderer'})

for span in viewcount:

print(span.string)

driver.quit()

I hope this helps!
