Dual Monitors and window.open(): Part 2

What? There is more?! Of course. Previously I tackled the horizontal setup of dual monitors, now we tackle the vertical!

So just like window.screenLeft versus window.screenX, window.screenTop only works in IE and window.screenY works in everything else. So here is the code I used to setup a window.*property*:

// Find Top Boundary of current Window
function FindTopWindowBoundary()
{
	// In Internet Explorer window.screenTop is the window's top boundry
	if (window.screenTop)
	{
		return window.screenTop;
	}

	// In Firefox window.screenY is the window's top boundry
	if (window.screenY)
		return window.screenY;

	return 0;
}

window.topWindowBoundary  = FindTopWindowBoundary;

Then just like the horizontal setup, I needed to find the Monitor’s Top Border. Like the horizontal counter-part, you need to check the negative y-axis scenario, which left me with this code:

// Find Top Boundary of the Screen/Monitor
function FindTopScreenBoundary()
{
	// Check if the window is off the primary monitor in a positive axis
	// X,Y                 S = Screen, W = Window
	// 0,0     ----------
	//        |          |
	//        |          |
	//        |        S |
	//         ----------
	// X,Y
	// 0,1280  ----------
	//        |  ---     |
	//        | | W |    |
	//        |  ---   S |
	//         ----------
	if (window.topWindowBoundary() > window.screen.height)
	{
		return window.topWindowBoundary() - (window.topWindowBoundary() - window.screen.height);
	}

	// Check if the window is off the primary monitor in a negative axis
	// X,Y                   S = Screen, W = Window
	// 0,-1024   ----------
	//          |  ---     |
	//          | | W |    |
	//          |  ---   S |
	//           ----------
	// X,Y
	// 0,0       ----------
	//          |          |
	//          |          |
	//          |        S |
	//           ----------
	// This only works in Firefox at the moment due to a bug in Internet Explorer opening new windows into a negative axis
	// However, you can move opened windows into a negative axis as a workaround
	if (window.topWindowBoundary() < 0 && window.topWindowBoundary() > (window.screen.height * -1))
	{
		return (window.screen.height * -1);
	}

	// If neither of the above, the monitor is on the primary monitor whose's screen Y should be 0
	return 0;
}

So now that we have the Top and Left boundaries written, we can open a window in any setup (2 monitors to 4 monitors to X monitors) using the following and be guaranteed that the new window will open in the same monitor as the parent window (except for IE where IE will not open windows in a negative axis).

window.open(thePage, 'windowName', 'resizable=1, scrollbars=1, fullscreen=0, height=200, width=650, screenX=' + window.leftScreenBoundary() + ' , left=' + window.leftScreenBoundary() + ',screenY=' + window.topScreenBoundary() + ',top=' + window.topScreenBoundary() + ', toolbar=0, menubar=0, status=1');

And thus the finale of opening a child window in a dual, quad, whatever monitor setup.
