How to find out mouse coordinates (setTimeout issue)?

Here's the code that explains it all:

$('#elem123').mouseenter(function () {
 s开发者_高级运维etTimeout(function () {
   //what are mouse coords?
 }, 650);           
});

Mouse coordinates after the 650 ms have elapsed, and relative to the element, I am guessing? (Adapted from http://docs.jquery.com/Tutorials:Mouse_Position)

See a working demo

var mouseX = 0, mouseY = 0;

$(document).mousemove(function(event) {
    mouseX = event.pageX;
    mouseY = event.pageY;
});

$('#elem123').mouseenter(function () {
    var t = this;
    setTimeout(function () {
        var localMouseX = mouseX - t.offsetLeft;
        var localMouseY = mouseY - t.offsetTop;
    }, 650);
});

Why use mousemove and offsetLeft? The reason is that the mouse position is only available to us when such an event happens (and only relative to the entire page). jQuery does not provide a more direct way to obtain it.

Read Mouse Position

Try

$('#elem123').mouseover(function (e) {
    var xPos = e.pageX;
    var yPos = e.pageY;
    setTimeout(function () {
       alert(xPos);
       alert(yPos);
    }, 650);           
});
