Get X, Y Coordinates of Mouse Within Box
The below code will give you the X, Y coordinates of a mouse click within a given box. Removing all the stuff about the offset, you can easily get the X, Y coordinates of the click relative to the browser window.
$(function() {
$("#demo-box").click(function(e) {
var offset = $(this).offset();
var relativeX = (e.pageX - offset.left);
var relativeY = (e.pageY - offset.top);
alert("X: " + relativeX + " Y: " + relativeY);
});
});
