Example

This example uses the onmousemove event to monitor the location of the mouse cursor on the screen. When the mouse cursor moves over the div object, a span object is updated with the clientX and clientY property values. The clientX and clientY properties are exposed by the event object.
<SCRIPT>
function fnTrackMouse(){
oNotice.innerText="Coords: (" + event.clientX + ",
" + event.clientY + ")";
}
</SCRIPT>
<DIV ID="oScratch" onmousemove="fnTrackMouse()">
<SPAN ID="oNotice"></SPAN>
</DIV>
