<p>This example uses the HTML DOM to assign an "onmousemove" event to a div element.</p>
<div id="myDIV"></div>
<p>Mouse over the rectangle above, and get the coordinates of your mouse pointer.</p>
<p id="demo"></p>

document.getElementById("myDIV").onmousemove = function() {myFunction(event)};
function myFunction(e) {
var x = e.clientX;
var y = e.clientY;
var coor = "Coordinates: (" + x + "," + y + ")";
document.getElementById("demo").innerHTML = coor;
