Event Object Properties

Although event handlers in the DHTML Object Model do not receive parameters directly, the handler can query the event object for data.

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.

Sample Code

<SCRIPT>
function fnTrackMouse(){
   oNotice.innerText="Coords: (" + event.clientX + ", 
      " + event.clientY + ")";
}
</SCRIPT>

<DIV ID="oScratch" onmousemove="fnTrackMouse()">
<SPAN ID="oNotice"></SPAN>

</DIV>
