Retrieving Element Event Location

The e object holds a lot of information about the Netscape 6 event. The currentTarget property, for example, reveals the element that caught the event. The following statement prints the currentTarget property value to the status window:

window.status = "Current Target = " + e.currentTarget

The status window is shown on the bottom left corner of Netscape 6 window. Notice that you have to pass the e object as a parameter to those functions which reference it. In the following example, we pass the e object as a parameter to colorItTan():

<DIV ID="demoDiv" STYLE="position:relative; left:100px; top:20px; width:250px; 
height:45px; color:blue; background-color:yellow;">Click me with the left button! 
</DIV>
<SCRIPT LANGUAGE="JavaScript">
<!--
var demoObj;
function init() {
  demoObj = document.getElementById("demoDiv");
  demoObj.addEventListener("click", colorItTan, false);
}
function colorItTan(e) {
  demoObj.style.backgroundColor = "tan";
  window.status = "currentTarget = " + e.currentTarget;
}
onload = init; 
// -->
</SCRIPT>

Get on Netscape 6 browser and play with this demo. Click the left button and observe the current target (DIV element object) in the status window.
