Get page generated with Javascript in Python

Question

I’d like to download web page generated by Javascript and store it to string variable in Python code. The page is generated when you click on button.

If I would know the resulting URL I would use urllib2 but this is not the case.

thank you

You could use Selenium Webdriver:

#!/usr/bin/env python
from contextlib import closing
from selenium.webdriver import Firefox # pip install selenium
from selenium.webdriver.support.ui import WebDriverWait

# use firefox to get page with javascript generated content
with closing(Firefox()) as browser:
     browser.get(url)
     button = browser.find_element_by_name('button')
     button.click()
     # wait for the page to load
     WebDriverWait(browser, timeout=10).until(
         lambda x: x.find_element_by_id('someId_that_must_be_on_new_page'))
     # store it to string variable
     page_source = browser.page_source
print(page_source)
