title: phantomJS how to get answer from JS scripts which starting after the page have loaded
body: <p>I'm looking for a solution for that question.</p>
  
  <p>The site load several JS scripts after page have loaded, it's working well, the page get the response from the scripts and render it to site page. </p>
  
  <p>But the scripts return JSON and I want to get this response in JSON, not from generated page. It's a more faster to use the script's answer than use selectors and cycles for get the information from page. </p>
  
  <p>I try to use <code>page.onResourceReceived()</code> but it's get me only analytics information, filenames stock and response sizes;</p>
  
  <p>How can I get the body of this response ? </p>
