cancelBubble	Sets or retrieves whether the current event should bubble up the hierarchy of event handlers.

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>
