This is how you find the mouse x, y position with JavaScript using jQuery:
var _mouseX = 0;
var _mouseY = 0;
jQuery(document).ready(function()
{
$().mousemove(function(e)
{
_mouseX = e.pageX;
_mouseY = e.pageY;
});
})The variables _mouseX and _mouseY will at all times have the updated mouse coordinates.
