Find window previously opened by window.open

javascript window.open

We've got the following situation, running from a single domain:

Page A uses window.open() to open a named window (a popup player). window.open() gives page A a reference to the window.

User now reloads page A. The reference to the named window is lost. Using window.open() to "find" the window has the unfortunate side effect of reloading it (undesirable). Is there any other way to get a reference to this window?

Try this:

var playerUrl = 'http://my.player...';
var popupPlayer= window.open('', 'popupPlayer', 'width=150,height=100') ;
if(popupPlayer.location.href == 'about:blank' ){
    popupPlayer.location = playerUrl ;
}
popupPlayer.focus();

It will open a blank window with a unique name. Since the url is blank, the content of the window will not be reloaded.
