You would want to use the "pageX" and "pageY" methods. For example, let's say that we had a single paragraph tag in our document. If we wanted the paragraph tag's text to dynamically display the coordinates of the user's mouse, we could do the following:
$('p').html("X Axis : " + e.pageX + " | Y Axis " + e.pageY);
This code says the following - When the document is ready to be manipulated, we'll listen for when the user moves his or her mouse (mousemove). When it does, we'll set the html of our paragraph tag to display the coordinates (e.pageX and e.pageY, respectively).
