How to find the center of the browser window using JQuery

How can I find out the coordinates of the center of the br开发者_如何学JAVAowser using jquery?

Why use jQuery? This can be done with simple enough plain JavaScript:

var horizontalCenter = Math.floor(window.innerWidth/2);
var verticalCener = Math.floor(window.innerHeight/2);

To use these, you may also have to append the units, px to the variables.

Untested, but this makes sense:

var intWidth = $(window).innerWidth();
var intHeight = $(window).innerHeight();

var xCenter = intWidth / 2;
var yCenter = intHeight / 2;

alert("The center of the window is: " + xCenter + "x " + yCenter + "y");
