How pass window handler from one page to another? (JavaScript)
<p>I have a very strange problem , please don’t ask me why do I need this…
I have a page1. Page1 has a link which opens new window (page2) using  window.open function.
chatWindow is a handler of child window with returns from window.open function.
Now I'm moving from page1 to page3 (by link <code>&lt;a href="...." target="_self"&gt;Some Text&lt;/a&gt;</code>). And I need to check on the page3 if page2 is close or open.
How to pass handler chatWindow from page1 to page3?</p>

<p>Thank you in advance!</p>
