Return the x and y coordinates of the new window relative to the screen:

var myWindow = window.open("", "myWin");

myWindow.document.write("<br>ScreenX: " + myWindow.screenX);
myWindow.document.write("<br>ScreenY: " + myWindow.screenY + "</p>");

More "Try it Yourself" examples below.


Definition and Usage

The screenX and screenY properties returns the x (horizontal) and y (vertical) coordinates of the window relative to the screen.


Browser Support

The numbers in the table specify the first browser version that fully supports the property.

Property
screenX Yes 9.0 Yes Yes Yes
screenY Yes 9.0 Yes Yes Yes

Tip: For IE8 and earlier, you can use "window.screenLeft" and "window.screenTop" instead (See "More Examples").


Syntax

window.screenX
window.screenY


Technical Details

Return Value: A Number, representing the horizontal and/or vertical distance of the window relative to the screen, in pixels

More Examples

Example

Open a new window with a specified left and top position, and return its coordinates:

var myWindow = window.open("", "myWin", "left=700, top=350, width=200, height=100");
myWindow.document.write("<p>This is 'myWin'");
myWindow.document.write("<br>ScreenX: " + myWindow.screenX);
myWindow.document.write("<br>ScreenY: " + myWindow.screenY + "</p>");

Example

Cross browser solution (using screenLeft and screenTop for IE8 and earlier):

// Open a new window with a specified left and top position
var myWindow = window.open("", "myWin", "left=700, top=350, width=200, height=100");

/*
If the browser does not support screenX and screen Y,
use screenLeft and screenTop instead (and vice versa)
*/
var winLeft = myWindow.screenLeft ? myWindow.screenLeft : myWindow.screenX;
var winTop = myWindow.screenTop ? myWindow.screenTop : myWindow.screenY;

// Write the new window's x and y coordinates relative to the screen
myWindow.document.write("<p>This is 'myWin'");
myWindow.document.write("<br>Horizontal: " + winLeft);
myWindow.document.write("<br>Vertical: " + winTop + "</p>");
