title: Catch the window.open from javascript
body: <p>I have a web page into a html iframe, the web page has a javascript function to open links, that function use the window.open method to open a new window.</p>
  
  <p>I cannot modify the javascript function (the page is made with mapguide), so I want to catch that call outside of the iframe to put the content of the new window into an ajax modal frame, instead of open a new window, is this possible?</p>
