Download html in python?

I am trying to load the html of a page requested using javascript when I click a link in a browser. I can load the first page because it has a common URL:

http://www.locationary.com/stats/hotzone.jsp?hz=1

But there are links at the bottom of the page that are numbers (1 to 10). Therefore, if you click on one, it will be, for example, on page 2:

http://www.locationary.com/stats/hotzone.jsp?ACTION_TOKEN=hotzone_jsp$JspView$NumericAction&inPageNumber=2

When I put this URL in my program and try to download html, it gives me the html of another page on the website, and I think this is the main page.

How can I get the html of this url that uses javascript and when there is no specific url?

Thank.

the code:

import urllib
import urllib2
import cookielib
import re

URL = ''

def load(url):

    data = urllib.urlencode({"inUserName":"email", "inUserPass":"password"})
    jar = cookielib.FileCookieJar("cookies")
    opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(jar))
    opener.addheaders.append(('User-agent', 'Mozilla/5.0 (Windows NT 6.1; rv:13.0) Gecko/20100101 Firefox/13.0.1'))
    opener.addheaders.append(('Referer', 'http://www.locationary.com/'))
    opener.addheaders.append(('Cookie','site_version=REGULAR'))
    request = urllib2.Request("https://www.locationary.com/index.jsp?ACTION_TOKEN=tile_loginBar_jsp$JspView$LoginAction", data)
    response = opener.open(request)
    page = opener.open("https://www.locationary.com/index.jsp?ACTION_TOKEN=tile_loginBar_jsp$JspView$LoginAction").read()

    h = response.info().headers
    jsid = re.findall(r'Set-Cookie: (.*);', str(h[5]))
    data = urllib.urlencode({"inUserName":"email", "inUserPass":"password"})
    jar = cookielib.FileCookieJar("cookies")
    opener = urllib2.build_opener(urllib2.HTTPCookieProcessor(jar))
    opener.addheaders.append(('User-agent', 'Mozilla/5.0 (Windows NT 6.1; rv:13.0) Gecko/20100101 Firefox/13.0.1'))
    opener.addheaders.append(('Referer', 'http://www.locationary.com/'))
    opener.addheaders.append(('Cookie','site_version=REGULAR; ' + str(jsid[0])))
    request = urllib2.Request("https://www.locationary.com/index.jsp?ACTION_TOKEN=tile_loginBar_jsp$JspView$LoginAction", data)
    response = opener.open(request)
    page = opener.open(url).read()
    print page

load(URL)
