title: Get page generated with Javascript in Python
body: <p>I'd like to download web page generated by <code>Javascript</code> and store it to string variable in <code>Python</code> code. The page is generated when you click on button.</p>
  
  <p>If I would know the resulting URL I would use <code>urllib2</code> but this is not the case.</p>
  
  <p>thank you</p>
