I'm trying to show/hide <DIV> tags in a javascript. The problem is that the tags that are hidden isn't correct. I guess it may be due to the child/parent relationship.

To replicate
Click on node1
Node 1 should hide Node1.1 but hides itself too!

Any ideas whats wrong?

<HTML>
<BODY>
<SCRIPT LANGUAGE="JavaScript">
function Hide(node)
{
var oVDiv=document.getElementById(node);
if (oVDiv.style.display == 'none')
{
oVDiv.style.display = '';
}
else
{
oVDiv.style.display = 'none';
}
}
</SCRIPT>

<div id="Main"><Span style="WIDTH:200px;BORDER-TOP-STYLE: outset; BORDER-RIGHT-STYLE: outset; BORDER-LEFT-STYLE: outset; BACKGROUND-COLOR: #ccff66; BORDER-BOTTOM-STYLE: outset"> Top </Span>
<div ID='Root' onClick="Hide('X')">Root
<div id='X' onClick="Hide('Y')" style='LEFT:10px;position:relative'>Node 1
<div id='Y' style='LEFT:20px;position:relative'>Node 1.1</div>
</div>
</div>
</div>
</BODY>
</HTML>

When you click on node 1, the onclick event fires (hiding node 1.1) but then the onclick event of root fires as well (as it should do, since node 1 is a child of root), which hides node 1. You may be able to prevent the firing of the second onclick event by returning false from the first.

Thanks adam. Sorry to be a muppet, but as you can probably tell, I'm not a java developer. Any idea how I may able to stop the parent event from firing?
Is it possible to tell which is the user fired event for instance?
