// The window.opener property refers to the page that spawned this popup.
// For example, if I wrote a function named callingPageFunction on my original page, I would call it from the popup like this:

$(window).unload(function() {
    window.opener.callingPageFunction()
});

var wnd = window.open("file.html", "youruniqueid", "width=400, height=300");
wnd.onunload = function(){
    // do something
    wnd.opener.dosomething();
};

//monitor the closing of a popup window
var win = window.open("http://dev.com/index.php?m=social&a=testLinkedIn",'','height=500,width=500');
var winTimer = window.setInterval(function()
{
    if (win.closed !== false)
    {
        // !== is required for compatibility with Opera
        window.clearInterval(winTimer);
        log('win closed...');
    }
}, 200);

example2.js

// using window.opener to access parent window object
// http://wisercoder.com/javascript-jquery-parent-windows/

// Open a new window
var myWindow = window.open("", "myWindow", "width=200, height=100");

// Write some text in the new window
myWindow.document.write("<p>This is 'myWindow'</p>");     

// Write some text in the window that created the new window            
myWindow.opener.document.write("<p>This is the source window!</p>"); 

example3.js

// we want to trigger an event in parent window when child window succeeds

var child = window.open("", "myWindow", "width=200, height=100");

child.opener.trigger('some_event')

// in parent window
$(window).on('some_event', function(){console.log('success!');});
